 lighter. Segment 3 of anteniiEe yellow, with a ring of light 

 brown at base, and the apex dark brown, concolorous with 

 the following segments ; wings apparently clear, at most 

 lightly tinged (the tips oidy protrude over the sides of tlie 

 body in the single preparation) ; cilia smoky. 



Head short and broad, only 1'7 times as long as broad, 

 cheeks faintly incurved behind eyes and then as gently 

 arched, set with a few strong- spines. Eyes prominentj finely 

 facetted, occupying al)out 3 the length of the head ; post- 

 ocular bristles long, 1'5 times as long as an eye. Antennee 

 2'3 times as long as the head, relative lengths of joints 

 a))proximately as follows : — 51 : 40 : 35 : 30 : 19 : 14. 



Pronotum about 0'5 as long as the head ; seise well- 

 developed, colourless, the outer postero-marginal pair about

 falcatus, Karny, and seycliellensis^ Bagn.
