 \entral braneli running- along the ventral margin of the stiginal 

 lield. the dorsal branch i)aler, spreading out across the stigmal 

 lield and a|)proaehing its fellow of the opposite side on the 

 middle line; a dense fringe of eonspicnous i-eddish hairs on the 

 tip of the lobe and c(mtinued on the outer doi'sal side for a 

 short distance toward the base. A few dusky brown spots on 

 the stigmal field between the stigmata; two small hairs occn

AnU-nnal sltrallis elongated (])late II, figure F, iilate 111. 

 figure D), the tip of the sheatii lying just before the end of the 

 middle metatarsus, in a few si)ecimens even reaciiing beyond 

 the tip. Cephalic crest (plate IT, E, b) very reduced, scarcely 

 l)rojecting beyond the fi-ont level of the antennap; viewed from 

 beneath (plate Til, J)), it is somewhat ([uadrate, the fore lateral 

 angles produced into small jxjinted lobes bearing a long hair 

 at the apex; viewed from the side (plate II, E, b) it is seen to 

 be notched, there being a second lobe, subequal to the ventral 

 one in size, immediately behind it, this also bearing a lai-ge hair.
