 of the abdominal segments with a distinct golden yellow pubescence. 



Female. Head very short but slightly broader than the thorax, 

 somewhat arched. Frontal stripe broad, slightly narrowed rather rapidly 

 about the lower one-third though the remaining part is parallel-sided, 

 about three and a half times as long as its broad, with two frontal calli, 

 in which the lower one is larger, roundish, moderately convex, occupying 

 more than the middle three-fifths of the space between the eye-angles, reddish 

 brown but darker above, shining though minutely striolate, while the 

 upper one is rather inconspicuous, long, narrow, and shining black ; 

 these two calli sometimes connected with a ocelligerous tubercle reddish 

 brown, small though distinct and sharply elevated, situated just front 

 the occiput ; frontal stripe black but densely obscured by a yellow or 

 pale yellowish grey dust (leaving all the callosities) and bearing some-

 from the ocelligerous tubercle to the lower callus so that the callosities
