BY CARL F. BAKER.

Eutettix pulchella, n. sp.--Size and gen-eral appearance of Eulettt: (Pklbsius)strobi Fh.Male: Face two-thirteenths wider than

long. Clypeus a half longer than broad,sides gently incurved towards the base,broadened beyond to nearly the width at

base, tip truncate. Lorae a fifth longer andthree-fourths the width of the clypeus.Genae broadly evenly emarginate below theeyes. Front a fourth longer than wide, twoand a third times the length of the clypeus.Vertex rather sharply transversely depressedbefore the tip, the lip thus formed not

strong but very obtusely rounded as viewedfrom the side; very obtusely rounded infront, length at middle but little greater thanthat at the eyes, width between the eyes twoand an eighth times the length. Pronotumtwo and one-sixth times wider than long,length nearly twice that of the vertex, cur-vature seven-twelfths of the length. Plateshort, very obtusely angled. Valves some-what attenuate towards the tips, about fourtimes the length of the plate, clothed on theouter edge with numerous long fine hairsand a few short weak spines.

Color: All beneath pale yellow with veryfaint indications of transverse arcs on thefront. Vertex back of groove, pronotumand scutel, even shining brown, the brownbeing thickly covered with small pale dots.The band on vertex may send forward fourshort more or less distinct points which areequidistant from the eyes and each other.Elytra whitish subhyaline, with brown areaswhich are thickly covered with fine palevermiculations. These areas occur as fol-lows: On all of clavus except outer marginof basal two-thirds; from apical third ofclavus a clearly defined band passes to costal

margin of elytra, towards which it becomesnarrower; from the middle of this band asubobsolete band extends to end of elj,tra,terminating in tips of two outer apical ceils.The brown areas on basal half of elytrahave sharply defined rather heavy contours.The nervures in basal half of corium arecolorless, in apical half brownish. Dorsumof abdomen broadly black. Some of the legspines darker. Length 4.5 mm.San Augustine (Ckll., 28, 234, and

z44). have also collected this species atFort Collins, Colorado. The Colorado spe-cimens vary from the typical form in havingthe brown above very dark, almost black, inbeing very much darker below, and in otherminor points. The specimens of this species,with others of seminuda, a western variety of

seninuda, and of 29klejGsius slrobi, form a

most interesting series. Strobi must beplaced in tuteltix, with the species of whichgenus it certainly shows the closest relation-ships. hope the female will soon be ob-tained.Thamnotettix tenella, n. sp.--Size and

general appearence of ThamnolelN caricis,but the vertex is not so produced, and the gen-eral color is pale so’rdid yellowish. Lengthfemale 3.5 mm.

Female Face little more than one-seventhwider than long. Front one-third longerthan wide, little more than two times thelength of the clypeus, sides slightly incurvedat the antennae. Lorae as long and two-thirds as wide as the clypeus. Genae broadbelow the lorae, gently obtusely angled out-

wardly, fi-om this to the angle of the eyestraight. Clypeus gently narrowed at the

base at the extreme tip somewhat narrowedand truncate. Vertex a third longer at themiddle than next the eyes, the length three-

fifths of the width between the eyes. Prono-turn twice wider than long, length once andfour-fifths that of the vertex, curvature one-half of the length, in front with the usualarcuate line. Hind margin of the last ven-

tral segment with a broad deep emargina-lion, the sides of which are strongly sinuate.

Pygofers nearly equalling valves, outer

apical margins slightly concave, and clothedwith long slender hairs.

Color pale sordid yellowish, brightest on

the head, darkest on the pronotum. Elytravery slightly infuscated. Abdomen above,except margins of segments, yellowish, mar-

gins of some of the basal ventral segtfientsblack. Legs with dark dots at bases oftibial

spines.Described from a single female taken at

Las Cruces on Sisymbrium (Ckll., 27).This is the species mentioned on page ooofthe Prelim. List. Hemip. Colo. It appearsto be a Mss. name of Dr. Uhler’s which was

never published. It is a quite common in-

sect in various parts of Colorado, and will

undoubtedly be found widely distributed in

the west. This species could hardly be con-

fused with T. caricis, which is larger, of a

much brighter yellow, and has a nuch more

produced vertex. It also differs in the formof the last ventral segment. Although a

good ThamnotelNx otherwise, yet this speciespossesses but one anteapical cell in the ely-tra. Had this character been correlatedwith the weak form in the definition of Limo-

tettix, I should consider that genus foundedon reasonable grounds, and this species a

good representative of it.

Athysanus acuminatus, n. sp, Ratherslender, general color pale fllvous; elytraexceeding abdomen. Length male 4.75mm.Male: Face little less than one-seventh

wider than long. Clypeus once and two-

thirds longer than wide, gradually broaden-ing to the apex, where it is truncate sides

slightly concave near the base, basal suture

curved. Lorae very large, a third longer,

and as wide as the clypeus at base, superiorlyacute. Cheeks broadly, evenly emarginatebelow the eyes, sides below the emarginationslightly sinuate, moderately broad below thelorae, attaining the tip of the clypeus. An-tennae with the six joints following the twobasal very unusually robust and distinct

(thread-like portion of the flagellum wantingin this specimen). Front one-ninth longerthan wide, edges slightly incurved at theantennae, below this straight to the clypeus.Vertex slightly convex, length at eyes five-sevenths of length at middle, the latter three-fourths of the width between the eyes. Pro-notum two and one-third times wider than.long, length a fourth greater than that ofthe vertex, curvature about three-sevenths ofthe length, hind margin straight. Elytraexceeding abdomen by about one millimeter,the outer anteapical cell connected with thecostal margin by two supernumerary cross-veins. Genitalia: Plate subangular posteri-orly, somewhat produced at the apex. Valveslong triangular, outer edges sinuate and fur-nished with long fine hair; apices producedinto long, slender acuminate processes whichform nearly one-third of the total lerlgth.Pygofers a third longer than valves, obtuselybut narrowly rounded at tips, furnished on

apical half of discs with numerous strongbristles in two or three rows.

Color pale fulvous throughout; slightindications of lighter concentric arcs on thefront; indistinct mottlings on anteriorborders of pronotum and vertex, the latterwith a fine dark median line on posteriorone-half. Elytra with one or two smallcircular or oval white spots on the discsof each cell, these spots surrounded andconnected by darker clouding most con-spicuous in the apical cells; veins brown,dark towards the apex.Described fi’om one male taken at Las

Cruces in September 894 (Ckll., 383).This species differs widely from any otherNorth American species of the genus. Itappears to be most nearly related to A.

relativus, but is very distinct fl’om thatspecies in size and other characters.

Agallia bigeloviae, n. sp.-- Form andcolor, nearly, of a small, pale A. sanguino-lenta. The female differs only as follows.More robust. Sculpturing on posterior

three-fourths of pronotum not nearly socoarse. Veins in elytra more prominentlybrown. Two medial brown dashes on pro-notum and vertex. Black spots on vertexlarger. Elytra barely equalling abdomen.Hind margin of last ventral segment thricestrongly notched, the middle notch very deep

and much more obtuse at apex than the latoeral, the two lobes thus formed obtuselyrounded at tips and much shorter than thehind angles of the segment. Length littlemore than 2 ram.

Described from a single female takenon Bigelovia at Albuquerque (Ckll., 46t6).This species is very nearly related to A.sanguinolela, but easily separated by theabove metioned characters, especially theform of the last ventral segment. A largerseries of this insect is much needed forstudy.

XII[. NEv SPECIES OF PROSAPIS.

BY T. D. A. COCKERELL.

The name Prosopis is preoccupied for a

genus of plants, on the flowers of whichthe bees of the genus 19rosopis are some-times found. I have therefore ventured to

write the bee-genus Prosabis (rpo-ar), a

name which accords with the assumed factthat it is one of the most primitive anaongbees.Prosapis bakeri, n. sp. ’, length 5 mm.,

black, with creamy markings, punctures ofhead and thorax fine and close. Head ratherbroad face not much narrowed below, white

below level of antennae, the white extendingas a pointed projection upwards in medianline, and on each side as a club-shaped pro-cess, curved over the antennal socket, and

remote from the orbital margin. The twosides of the median pointed process meet at

an angle of almost 45 Flagellum very dark

brown, paler beneath. Scape swollen, trun-cate, its anterior side white and posterior side

black. Prothorax all dark, except the usual

creamy-white spot on tubercles, which pre-sents no dark dot. Tegulae with a yellowspot. Pubescence all pale. Pleura rather

hairy closely and rather coarsely but not

very deeply punctured. Dorsal wrinkles ofmetathorax rather feeble. Wings grayish-

hyaline, nervures and stigma piceous.Second submarginal narrowed one-half tomarginal. Femora black tarsi yellowish-white with the ends darkened anterior tibiaeyellowish-white in front; middle tibiae withthe basal fourth, and hind tibiae with thebasal two-fifths yellowish-white. Abdomenmoderately shining, very minutely punctured,slightly pubescent at sides, but without anyconspicuous hair-bands or patches.ttab. Colorado seven miles W. of Liver-

more, Larimer Co., July r, r8’94 7000 feet(C. F. Baker).Allied to rudbeckiae, but differs by the

white fitce, the half white scape, and. thewhite frontal process cui’ving over the anten-nae, etc.Prosapis wootoni, n. sp. ( about 5

mm. long, black with pale dull yellowmarkings, head and thorax closely punc-tured. Pubescence pale, including thatof dorsum of mesothorax. Head ratherlarge and broad, face moderately narrowedbelow. Antennae entirely piceous, scapeonly moderately swollen. Face belowantennae pale yellow, the yellow formingonly a rounded projection in the medianline, but at the sides produced upwards
