behind the lung-slits. Mr. Kincaid, of Washington State, has 

 sent me another Leptonetid, belonging to another genus and 

 agreeing quite well with Ochyrocera, though the inferior spin- 

 nerets are widely separated. 



The genera may be separated by the position of the side-eyes. 



The s. e. form a diverging line and touch by their sides . . . Usofila. 

 The s. e. touch at one point and form a single opening within Ochyrocera.

Psiloderces Simon, Amer. Soc. Ent. Fr., 1892, p. 40. 

 Usofila gracilis Keys. Length 11 mm. — Pale yellow, abdomen whitish; 

 cephalothorax broadlj' rounded, quite high a little behind eyes, smooth ; 

 the s. e. are more than their diameter from the slightly larger m. e. 

 Mandibles quite prominent and diverging ; sternum plainly longer than 

 broad, triangular, legs long, first pair longest, the femora, especially femur i, 

 slightly incrassated, all with scattered hairs ; abdomen globose, with a 

 few scattered hairs, sometimes a white spot above spinnerets. Male pal- 

 pus consists of a pyriform bulb, with a short curved tube, tarsus nearly as 

 long as the bulb, tibia and patellae subequal.

OCHYROCERA Simon. 

 Simon, Proc. Zool. Soc. London, 1891, p. 565. 

 Ochyrocera pacifica nov. sp. — Length 12 mm. Cephalothorax, legs and 

 palpi yellowish ; abdomen above gray, sternum and venter blackish, eyes 

 surrounded with black. Cephalothorax but little longer than broad, 

 truncate behind, slightly arched, highest behind eyes, no median groove 

 and radial furrows extremely faint; clypeusnarrower than length of eye-row; 

 s. e. close to the equal m. e. Mandibles vertical, barely diverging, quite 

 long, with a row of stiff hairs on superior margin; lip full as broad as long; 

 sternum triangular, barely longer than broad in front. Legs slender, first 

 pair longest, third femur longer than cephalothorax, all incrassated toward 

 base, and with scattered hairs. Abdomen globose, with a few hairs above, 

 spinnerets short, the inferior pair longest and quite wide apart at base, 

 disclosing a distinct colulus. Region of epigynum swollen, a pale area 

 containmg a transverse reddish patch. 



One female, Olympia, Washington (Trevor Kincaid). This 

 differs from Ochyrocera in having the inferior spinnerets widely 

 separated, and in the shorter lip ; yet it is much nearer to this 

 genus than to any other, and I dislike, at present, to erect a 

 separate genus for it.
