Oiiapliosa aiiK^rioaiia uov. sp. — Lentjth 7.7 mm.; ceph. 3.4 mm. long, 

 2.3 mm. wide-. Ccplialoiliorax yellovv-browii, with black on the ends of the radial 

 furrows and just behind the pars ceithalica ; mandibles red-brown; legs, palpi 

 and sternum yellow-brown. Legs darker on the tibiic and metatarsi. Abdomen 

 black, spinnerets brown ; cephalotborax longer than tibia and patella i ; both 

 tibiie i and ii have two spines beneath at tij>, no others; posterior rows of eyes 

 strongly recurved, p. m. e. about their diameter apart, and nearly three times 

 that distance from the larger p. s. e. : sternum plainly longer than broad, trun- 

 cate in front, broadest at coxae ii, pointed behind. Abdomen depressed, truncate 

 at base, with a fringe of stiff hairs, once and a third longer than broad ; the 

 cavity of the epigynum is divided into two parts; the anterior part is once and a 

 fourth longer than broad, truncate iu front and connected behind to the very 

 mucli narrower posterior part, which is about twice as long as wide ; the anterior 

 part contains a large oval body, pointed in front, and, filling the cavity behind, 

 it extends into and fills the posterior cavity; in its middle there is a somewhat 

 triangular mark ; behijid the epigynum there is a parted line as in the other 

 species. 



One specimeu, Ithaca, N. Y. ; its small size and shape of epigy- 

 nnni readilv distinfi'uishes this from the other species of the genus. 



C«iia|»liO»«a parviila nov. sp. — Length .'').4 mm.; ceph. 2.5 mm. long, 1.9 

 mm. wide. Cephalothorax yellow-brown with black marks on radial furrows, 

 and a black V at end of pars cephalica ; mandibles red-brown ; femora, especially 

 the anterior pairs, quite yellow; posterior femora more blackish, rest of legs 

 tinged with red-brown; palpi yellowish; sternum and abdomen black, spinnerets 

 pale; cephalothorax longer than tibia, plus patella i, quite narrow in front; p. m. 

 e. less than their diameter apart, hardly twice their diameter from the larger 

 p. s. e. ; tibiae i and ii without spines ; sternum nearly oval, but truncate at base. 

 Abdomen depressed, truncate at base, one and one-third times longer than broad : 

 the epigynum is nearest to G. hnimaHs, but the middle finger is not pointed at 

 tip. but blunt; it is shorter and divided by a transverse line; there is no basal 

 striate body as in that species, but a rather broad plate containing a small rounded 

 cavity in its posterior margin ; the usual jiarted line behind the epigynum ; the 

 ^ jialpus has a spur on the outer side of tibia, the palpal organ has hard plates 

 at base as in G. brumalis, but the tube is longer, though not so long as in G. coii- 

 spersa, and the hook is stouter even than in the latter si)e(ies. 



A female, Hanover, N. H. (C. M. Weed) ; a male, Franconia, 

 N. H. (Mrs. A. T. Slosson). Its small size, black sternum and 

 peculiar epigynum, distinguish it from the other species. 



Prostliesiiiia floriduna nov. s,i.— Length 9 6.5 mm. ; ceph. 2.3 mm. 

 long. Lri mm. broad, patella, jilus tibia i, 2 mm. long. Cephalothorax yellowish ; 

 legs paler yellowish, except, tibiae, metatarsi and tarsi of anterior paii-s, which are 

 red-brown; mandibles red-brown; sternum yellowish. Abdomen pale whitish 

 gray ; everywhere clothed with fine blackish hair and stouter bri.stles ; cejjhalo- 

 thorax long and low : a. m. e. larger than other eyes, less than one-half their 

 diameter ai)art, and still closer to the a. s. e. ; i)OSterior row slightly longer than 

 tile anterior one, and i)lainly ])rocure(l ; ii. m. e. oval, obliiiiic, about their diam- 

 eter apart, scarcely so far from the j). s. e. ; qua.lranglo of ni. c. fully as long as
