than broad, finely granulated medially, very finely rugose at the tip, 

 with a fringe of long, light fulvous hairs at the basal margin, and 

 without an apical fringe of hair at the apical margin ; second sternite 

 with scattered, shallow, elongate punctures, the median area occupied 

 by a pit densely filled with fine hairs ; sternites 3-6 punctate, with a 

 fringe at the apical margin consisting of long, black hairs medially 

 and a few light fulvous hairs laterally ; last sternite irregularly punc- 

 tate, the postero-lateral angles rounded. 



Legs black, clothed with black hairs. 



Wings dark fuliginous; veins r-m and R., adjacent on vein r. 



Holotype.—K£i\Q, Cat. No. 40744, U.S.N.M., California. 



This species is quite like cotulla of the fulvoldrta group in general 

 appearance but differs in the following characters: first abdominal 

 segment subnodose, last tergite longer than broad, postero-lateral 

 angles of last sternite rounded, veins r-m and Eg adjacent on vein r. 

 The genitalia of this species are also quite different from those of 

 cotulla as will be seen from the figures.
