Pangoniin&. 

 Dorcalcemus f } gen. nov. 



Agreeing with Pangonia, Latr. (sensu stricto), except that 

 in the wings the fourth as well as the first posterior cell is 

 closed before reaching the margin, and that the wings themselves, 

 instead of tapering to the distal extremity, are more bluntly 

 rounded at the tips, thus having a characteristic shape, which, 

 by comparison with that seen in, e. g., Pangonia rostrata, 

 Linn., is relatively short and broad. Ocelli wanting. Face in 

 both sexes without a shining callus on each side. 



Typical species, Pangonia compacta, Austen (Ann. & Mag.
