CALLOSAMIA nov. gen. 



Front of the head narrow compared with Samm, and not so hairy. 

 Antennae broadly pectinated, in 9 two-thirds as broad as iu % . Man- 

 dibles obsolete. Maxillae very short. Mentum and labrum coalesced, 

 short and rounded in front, bearing the small short depressed cylicdri- 

 cal clavate palpi, which are thinly clothed with long scales. Fore 

 wings more than twice the length of the whole body, falcate. Hind 

 wings much produced at the anal angle. The first median nervule in 

 the primaries subdiv^ides a little beyond its origin. 



I should here state that soon after beginning my studies upon this 

 family, Professor Agassiz indicated t(j me that S. promefhea should 

 f jrm the type of a separate genus from tS(iinia. 



Diifers from Samia in its slighter form, more falcate primaries, in 

 having the hind wings much longer behind, while in the middle of the 

 wings are partially transparent triangular sjiots.
