 their diameter apai-t. much closer to a. s. e. ; p. m. e. once and a half thei/ diam- 

 eter apart, scarcely so far from the p. s. e. ; mandibles stout, vertical ; sternum 

 oval; abdomen once and two-thirds longer than broad, densely hairy, tracheal 

 openings a little behind the middle of venter; the epigyuum consists of an area 

 longer than broad, broadest just behind the middle, anterior sides concave, poste-

GayeiiUM luai'iilata nov. sp. — Length 4.4 mm. C'ephalothorax yellow- 

 ish, with a black dentated stripe each side, and a line behind each p. m. e. Ab- 

 domen whitish, with a large black spot each side at base, two converging rows of 

 four very distinct and quite large spots, a large apical spot, and some small, scat- 

 tered .spots black; the sides mostly black ; venter with a few black spots: two 

 black lines on the mandibles. Legs yellowish, with some bands and black spots, 

 sternum pale; similar to A. celer, J3ut the % palpus has the swelling on the tibia 

 larger, and the projection of the tibia has the outer part much smaller, while the 

 inner part is shaped differently, being longer, contracted in the middle and bi- 

 lobed at tip; the tarsus is very similar, the central strip is more slender and 

 recurved at tip, and the tube is longer.

I at first thought this was A. celer Hentz, but Heutz says that the 

 spots on the abdomen are indistinct, which would agree with Key- 

 serling's incerta rather than this species. Moreover, this species is 

 probably (piite rare, while A. mcerta is very common. 



Cliibioiist iiiflCKta nov. sp. — Length 4-6 mm. ; ceph. 2.2 mm. long, 1.7 mm. 

 wide ; patilla, plus tiliia iv, 2 mm. Cephalothorax pale yellowish, growing darker 

 on the head, no )nargiual line ; mandible dark red-brown ; lip and maxillte red- 

 brown ; sternum yellowish ; legs pale ; abdomen reddish or brownish, showing a 

 faint basal si)ear-mark : venter whitish, epigynum black; cephalothorax clothed 

 with white and black hairs and black bri.stles. Head moderately broad ; all eyes 

 about equal; a. m. e. about their diameter apart, barely so far from a. s. e. ; p. m. 

 e. over three times their diameter apart, over twice tueir diameter from p. s. e. ; 

 mandibles large and prominent; sternum oval, truncate in front. Legs mode r- 

 erately stout, only one spine beneath on tibia iii : the epigynum is an area 

 broader behind than in front, the posterior margin sinuate, two large circular 

 cavities about their diameter apart, the portion between them extends behind as 

 a truncated lobe; the male palpus has a large, stout projection on the outer tip 

 of tibia, truncate at the end : the tarsus is oblong, about twice as long as broad, 

 truncate at tip, the tube is bent at a right angle and then curves back on the outer
