Dark blackish brown, end of tube and tarsi somewliat 

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

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

 the following segments ; wings apparently clear, at most 

 lightly tinged (the tips only protrude over the sides of the 

 body in tiie single preparation) ; cilia smoky. 



Nead 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 prominent, finely 

 facetted, occupying about 3 the length of the head ; post- 

 ocular bristles long, 1-5 times as long as an eye. Antennae 

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

 approximately as ft.llows :— 51 : 40 : 35 : 30 : 19 : 14. 



Pronotum about 0*5 as long as the head ; setse well- 

 developed, colourless, tlie outer postero-marginal pair about 

 0'8 and the mid-lateral 05 as long as the median length of 

 ])ronotum; pair at anterior angles shorter. Pterothorax 

 stout, transverse. Wings broad, reaching to sixth abdo- 

 minal segment, with cilia very closely set. Femora irregu- 

 larly spino.?e ; fore-tarsus with tooth. 



Abdomen heavy, broader than pterothorax, gradually 

 narrowing posteriorly. Tube long and slender ; 1*2 times as

 Only three other species are known to me wherein only the 

 third antennal joint is yellow — namely, denlicollis, Bagn., 

 falcatus, Karny, and seychellensis, Bagn.
