MK. A. G. BUTLBE ON THE SPHINGID^. 627 



The abdomen and secondaries of the type are wanting, so that is impossible to decide 

 positively as to its position ; the long whip-like antennae at once distinguish it from 

 Perigonia. 



Doubtful Sphingidj;.

Surinam. 



Allied apparently to nothing else ; it is best placed near the Sphinx australadce of 

 Donovan, so far as I can judge by Cramer's figure. Mr. "Walker suggests its possible 

 affinity to the genus Calliomma ; but the structure of that genus seems quite distinct. 

 It may perhaps be a Corymbia (Noctuidae).

Surinam. 



As I have never seen the species figured by Cramer, and as it differs too much from 



' I would ratherseethisgenus among the Bomiycj'fZfE than in the iSp^in^jrfa;; I believe it has about us much right 

 to be in the latter family as the Geometrine genus (Enochromia, which has even a more Sphingoid appearance ; 

 however, as I am not acquainted with the early stages of Arctonotus, I leave it provisionally at the end of the 

 S^Mngidai.
