is represented by a short "comb;" submesotibial bristle absent; 

 posterior surface of tibia with a single bristle, this on its middle 

 line on distal half (no bristles on this surface near median dorsal 

 ridge). Ventral surface of anterior coxa with two irregular rows 

 of bristles, one at each side: tibia with a single bristle on posterior 

 surface distal to center and on middle line. Chatotaxy. The two 

 posterior pairs of anterior dorsocentrals are scarcely, if at all, 

 weaker than the two anterior pairs of postsuturals, one or two 

 weaker and sometimes inconspicuous pairs anterior to these; ac- 

 rostichals absent; inner presuturals absent: three pairs posterior 

 dorsocentrals, last somewhat the strongest; prescutellar acrosti- 

 chals present; usually four sternopleurals, sometimes two, three 

 or five; subnotopleurals slender, but distinct. 



Abdomen: Outline almost elliptical; nota clothed above with 

 short reclinate bristles, beneath with longer almost erect hair. 

 Vestiture of the three ventral plates practically of same length and 

 not short. Spiracles of nota on each side in a straight line, the 

 rows parallel to longitudinal axis of abdomen and to each other. 

 Fourth segment may or may not be wholly or in part of same color 

 as genital segments. Chcetotaxy. Second segment with weak, 

 inconspicuous, decumbent marginal bristles; third with two, only 

 occasionally with weaker ones between these and laterals, latter 

 become more slender ventrally but extend well toward ventral 

 plate, fourth with complete row ending ventrally at forward turn 

 of margin. 



Genital Segments: Large, protuberanr, filling entire opening 

 of fourth segment and notum fits them closely; dull orange, some- 

 times yellowish pollinose: first, much larger than second; normally 

 with two rows of bristles, first just anterior to line of fusion of 

 sixth and seventh nota, second on posterior margin, either row may 

 be absent, when both are present those of marginal row the weaker; 

 vestiture sparse and only on posterior half of sixth notum, an 

 irregular line of minute bristles anterior to first row of bristles; in 

 profile showing a more or less distinct "hump:" second, in normal 

 position directly beneath first, and appears discoidal (when seg- 

 ments are pulled out is more triangular in profile) ; vestiture sparse, 

 scarcely longer than that at first. Forceps (rarely exposed) ; small, 

 base without upward flap-like extensions, prongs attenuated, tips 

 darkened and bent slightly forward but not approaching each other.
