that I doubt if A. lophotes will belong to Nycteribosca, but 

 rather to the genus Raymondia. 



I have made some drawings of these specimens from Em- 

 ballonura, and wish to call attention especially to the furcate 

 tip of the antennal arista, and the spines on the tip of the body, 

 and to the chitin rings near the posterior spiracles; these 

 rings bear bristles. These characters figured will serve to 

 distinguish this species from those already known, so I pro- 

 pose to call this species Ascodipteron emballonurce , athough I 

 suspect that when its life-history is known it will be shown 

 to be the same as some species of Streblidse already described 

 from Insulinde.
