 and distinct shades and bands in wing maculation. The 

 abdomen is rarely banded, and there are few sober grey 

 forms represented ; on the contrary, particularly in 

 America, some are of a most beautiful and graceful 

 description. Certain genera, as in the Ambulicinae, have 

 the anal segment of the abdomen in the males expanded 

 laterally, an aspect approaching that of Macroglossinae in 

 this respect. 



Sphingina. 



When we turn to the Sphinginae, we find these, as a 

 rule, sober grey or brown, the usually moderately narrow 

 and pointed wings of even outer margin, not sinuate or 

 angulated as in the Chcerocampinse. For the broad 

 shades or bands of the latter, we have here a maculation 

 consisting either of simple, undulated, transverse lines, 

 or of longitudinal, interspacial dashes. Sometimes we
