BY HARRISON G. DYAR, WASHINGTON, D. C.

Synomila subockrearia Hulst.tgg.-- Elliptical, sides oundedly flat-

tened, truncation rounded, a little oblique,outline in general a little irregular, no enddepression. Reticulations circular-hexago-nal, rounded, raised, the cell areas forminground pits like a thimble all over the sur-

face. Pale yellowish pink, turning darker.Size .6 )< .5 X .4 ram. Laid loose, easily rol-ling around.Stage LmHead rounded, erect, slightly

bilobed, free, dark dull brown width .3 mm.Body moderate, normal, translucent sordid

whitish, marked with sordid vinous brown.

October, 9o PSYCItE. 408

A greenish dorsal line, dotted on the rathernumerous, obscure annulets, grayish in tone,diffuse outwardly with traces of a similar,single, subdorsal line five broad, transverse,vinous, segmentary bands on joints 5; to 9.Anal feet spreading, the abdominal feet allpale. Tubercles and setae minute, incon-spicuous, short, capitate. Thorax dorsallydiffusely shaded in brown.

Stage //.--Head smoky luteous, darkerexcept in two lines from the clypeus on eachlobe width .4 ram. Body normal, moderate,sordid luteous with five broad, transverse,vinous, segmentary bands as before, unitedby numerous fine, evenly spaced, longitudi-nal lines of the same color, fainter at theends, addorsal, subdorsal, lateral, etc. Tuber-cles whitish with short, capitate setae alsowhitish, the enlarged ends looking like dotson the body. Segments finely annulate.

Stage III.-- Head rounded bilobed, brown,pale mottled, a pale curved line on each lobeabove; dotted by the white capitate setaewidth .6 ram. Body whitish with fine red-brown lines, slightly waved, about as wideas the spaces, blotched on the diffuse trans-verse bands of joints 5; to 9. Feet dark.Finely annulate; appears dotted by thewhite capitate setae.

Stage IW.--Head round6d, erect, ratherstrongly bilobed, brown, black on the face,pale, dark mottled on sides and vertex; setae

pale, short, capitate; width .85; mm. Bodymoderately robust, the ends contracted, nor-

mal, segments rather numerously annulateespecially at the ends subventral foldridged, prominent on the posterior edges ofthe segments. Tubercles and ii well sepa-

rated, ii on a slightly prominent annulet.Nearly uniformljz entirely dark brown; seg-ments a little lighter patched dorsally withtraces of a pale, narrow, dorsal line, on eachside of which are rather irregular, faintlytraced, blackish markings intersegmentally,forming a broad, geminate dorsal band.Feet short, dark; setae with pale capitatetips, short. Subventral ridge marked andblotched in pale. After being in this stagetwo weeks the larvae were thick and robust,tapering from joint 5; to the small head.Dark brown, finely annulate, shaded in paleron the back; subventral fold pale andblotched broadly in pale centrally on thesegments. Marks all obscure.Stage V’.--Head rounded bilobed, erect or

with the apex advanced, clypeus depressed.Brown-black, apices of lobes lighter brownmottled; setae short, white, capitate widthmm. Body robust, attenuated somewhat

before, finely annulate. Dark brown-black,variegated with obscure tessellated markingsin lighter brown in dorsal, diamond-shapedpatches, terminated in obscure black X-marksin the incisures and a black subdorsal line.All the markings are clouded, faint and mot-tled. Subventral fold prominent. Setaeshort, pale, capitate. The dorsal tessella-tions are palest on joints 5; and 6, somewhatring shaped on joint I.

Larvae from Golden, Colorado, eggs July7th. The larva grew slowly and died Octo-ber 27th but seems to have been in the laststage. It is remarkable, however, that thecapitate setae should persist so long. Thelarva was fed on Polygonum; natural food-plant not determined.
