$ . Eighth and ninth joints of the antennae with a minute spine 

 beneath, tenth to twelfth slightly excavated beneath, apical joint 

 longer than the penultimate, distinctly curved and rounded at 

 the apex. Fore tarsi normal, the basal joint with six spines on the 

 outer margin, fore femora not serrate, intermediate femora with one 

 or two small spines beneath near the apex, not distinctly serrate, 

 basal joint of intermediate tarsi normal, intermediate tibiae not 

 produced at the apex. Seventh dorsal segment broad, narrowly 

 truncate at the apex, the sides not sinuate. Second ventral segment 

 with a longitudinal carina which is gradually raised into a rounded 

 tubercle at the apex, the surface of the segment closely and evenly 

 punctured ; sixth ventral segment with a small, low, rounded 

 tubercle in the middle ; seventh ventral segment with three longi- 

 tudinal carinae placed rather far apart. Wings rather short, not 

 reaching when closed much beyond the apex of the third dorsal 

 segment ; cell of the hindwing emitting only one distinct vein from 

 the apex. 



9 . Similar to the male except in the usual sexual characters ; 

 the sixth dorsal segment with a very large yellow apical spot, the

 hindwing, and the carinae of the seventh ventral segment 

 ( $ ) are far apart.

9. Eyes strongly convergent towards the clypeus, separated at 

 the base of the clypeus by a distance scarcely exceeding half the 

 length of the scape ; clypeus very short, the anterior margin dis- 

 tinctly raised. Antennae short, about as long as the thorax without
