The genus ALLOGOSA Banks, 1900. 

 (Proc. Acad. Nat. Sci. Phila., p. 537.) 



Cephalothorax glabrous or nearly so to sparsely pubescent. Anterior 

 tibiffi armed beneath with three pairs of spines, of which the third pair 

 is apical in position and all of which are moderate to minute in size, 

 either armed or unarmed laterally. Anterior row of eyes straight to a 

 little procurved, from longer to shorter than the second row; anterior 

 median eyes larger than the lateral, more or less; clypeus narrow, at 

 most as wide as the diameter of an anterior lateral eye; eyes of second 

 row of moderate size, much less than their diameter apart; quadrangle 

 of posterior eyes trapeziform, wider behind than in front. Labium 

 longer than wide, well attenuated anteriorly; basal excavation short, 

 about one-fourth the total length. Spinnerets very short, anterior and 

 posterior pairs subequal in length, Epigynum simple, presenting no 

 true guide, or but weakly furrowed, the spermatheca opening free 

 posteriorly. Bulb of male palpus bearing a scopus which is exterior 

 in position.

Cephalothorax arched convexly behind, strongly attenuated anteriorly ; 

 pars cephalica narrow and inclined anteriorly, rather low; face with 

 sides convex and sloping outward from above below; posterior eyes 

 seen from above well removed from sides of pars cephalica. General 

 appearance of cephalothorax much like that of a Drassid. In the 

 known species the cephalothorax is entirely without distinct pale 

 stripes, or with a median paler band weakly contrasting. 



Chelicerce rather weak ; lower margin of furrow armed with three 

 teeth, the superior with two. Legs short; posterior tarsi simply setose, 

 and the anterior either entirely setose or with sparse lines of scopular 

 hairs at the sides. 



Excepting as to curvature of the anterior row of eyes, this genus is 

 much like most species of Simon's old genus Tricca, now withdrawn 

 by its author into Lycosa. It has the same form of cephalothorax
