> I include myops, which has the margin of secondai'ies entire and agrees better with 

 aslylus in others respects. I am of the opinion that Butler is wrong in referring ^'awiaics/jsw of 

 Drury to myops ; as Prof. Lintner has pointed out, it agrees better with ge?ninatus. Paonias 

 is characterized by botli wings being more regularly scolloped, approaching Cressonia and 

 Laothoe. 



2 This genus differs in the shape of primaries and secondaries from Smerinthvs. The 

 branches on primaries are shorter, and the median vein runs close to the subcostal for a third 

 of its length. It includes coecus and kmdermanni.
