In the unique type of D. pallida, it was not possible to inter- 

 pret the obscure venation, but apparently there were no cross 

 veins in the subcostal. Mr. Muir has collected a .species at Rew^a 

 which I place here. The venation is somewhat like that of 

 Platymctopius ; there are two discoidals. the medians being nearly 

 twice as long as the exterior and extending beyond it basally and

 subcostal, and 5 apical cells and an appendix. The wing cells 

 are also peculiar.
