384 University of California Puhlications [Entomology 



Abdomen sessile, unarmed, the venter fiat, tlie last ventral segment 

 nearly semicircular. Squama forming an acute upturned hook, not 

 fused with the ramus; sagitta of irregular shape, bearing an appar- 

 ently movable oval process, the apical part of which is scarcely chiti- 

 nized and bears a patch of setae ; uncus broad, flat, obtuse, not barbed 

 at base, but with a minute tooth about the middle of either side. 



5. Eyes not so large as in the male, their emarginatious less sharp, 

 the face, between the eyes, much broader than in the male, the bases of 

 the antennae much more distant from the eyes; clypeus less deeply 

 bifid at apex than in the male ; mandibles blunt ; with a tooth on the 

 inner margin before the apex; antennae as in the male, but 12-seg- 

 mented. 



Trochanter, femora and other segments of the legs simple. The 

 middle tibia show sometimes one and sometimes two apical spurs. 



The venter is less flat than in the male. 



The generic identity of Psiloglossa simplicipes with Euparagia was 

 suggested to me by Dr. Bequaert. Acting upon this suggestion, we 

 together established the certainty to our mutual satisfaction. 



Key to the Species of EUPAEAGIA 



Vertex with two prominent smooth tubercles behind the ocelli; vertex and front 

 coarsely, irregularly punctate; pronotum coarsely punctured; mesonotum 

 rugose; posterior face of propodeum with transverse rugae at the angles, 



' almost smooth in the middle, but with a few scattered irregular" large punc- 

 tures, its lateral faces smooth medially, finely punctate below and slightly 

 aeiculate above and behind; clypeus of the female with minute punctuations 

 ■ and scattered coarser punctures maculiceps Cameron. 



Vertex simple without tubercles, vertex and front uniformly granular punctate; 

 pronotum finely punctate; mesonotum evenly, finely granular-punctate; 

 propodeum closely evenly punctulate; clypeus of the female longitudinally 

 aeiculate maculifrons Cresson.
