THE PHALANGIDA OF NEW YORK. By NATHAN BANKS.

The State of New York extending from Lake Erie to the

Atlantic coast lies in parts of several quite different faunal regions;

Viz., the WVestern or Prairie, the Northern or Mountains, and the

Atlantic or Southern region. So it will doubtless appear that the

Phalangid fauna of the state is quite extensive, and this list can

only claim to be preliminary. Most of the species that I give, have, however, never been recorded from the State.

There are two famnilies represented, both belonging to the

Phalangida Plagiostethi (Palpatores). A claw at end of palpus. Phalangidw. No claw to palpus .Nemastomatidee. Of the Nemastomatide we have but one genus and species,

Phlegmacera cavicoleus Pack. This was decribed from the caves of Kentucky but is not a strictly cave form as I have collected it in a gorge at Ithaca, N. Y., and Prof. C. M. Weed records it from

New Hampshire under the name of Sabacon spinosus. The Phalan

gide, the more common forms of the order, and ordinarily called

"daddy-long-legs',, "harvest-men", etc., embrace several genera. Several prominent spines on second joint of palpus 2

Femur I much shorter than body. in females not as large as

I width of body .Leptobunus. 5 Femur I longer than body, or in same females a little shorter

than body .Liobunum.

Of Caddo we have but one species. C. agizlis Banks, found on Long Island. Its enormously large eyes readily separate it from all other Phalangids. It belotngs to the southern fauna as it is known from D. C.

Oligolophus and Lacinius are each represented by a single species, O. pictus Wood and L. ohioensis Weed, both of which occur at Ithaca, N. Y.

MARCH 1894.) BANKS. PHALANGIDA OF NEW YORK. 41

Phalangium has one species P. cinerecum Wood, which doubtless occurs throughout the State, it belongs to the Boreal fauna, but it occurs as far south as Long Island. It is usually found near

buildings. Leptobunus was erected for a Californian species, but two

other species were placed in it, one of which, L. grande Say, I have received from Poughkeepsie, N. Y., cellected by Mr. Van

Ingen. It is a southern form, and this is doubtless as far north as

the species extends on the Atlantic coast. Of Liobunum, I have seen six species from the State. The

males may be separated as follows: A small projectioni on second joint of palpus L. calcar.

No such projection . .2

2 Palpi wholly black, legs black L. nigropalpi. Palpi not wholly black . . . .. . 3

3 Dorsum with a distinct black stripe L. dorsatum.

Dorsum without distinct stripe . . . .4 B Body very small, 3-4 mm. long, legs darker near tips . L. politum.

Body lar-ger, 5-8 m-m. long, legs not darker near tips . . . 5 Dorsum brownish, eyc-tubercle smooth . . . L. ventricosum. Dorsum goldeni, eye-tubercle spinose . . . L. verrucosum.

Liobunum dorsatum Wood.

This is by far the most common species in the northeastern United States. On Long Island the males seem to be more numer ous than the females.

/iobunum ni,ropalpi Wood. This is an uncommon species; it occurs sparingly at Ithaca, N. Y.

Liobunum calcar Wood.

This is a quite rare form, I have one male from Ithaca, N. Y.

Liobunurm ventricosum Wood. This species is common in the State; unlike the other species

of the genus this is adult in early summer. The young were called L, formosum by Wood.

Liobunum verrucosum Wood. This beautiful species is quite rare; I have taken it several

times on Long Island.

Liobunumr poliurm Weed. This is a much smaller species than the other forms. It is

not uncommon on Long Island.
