Sub-Generic Character. 



Anterior wings with the outer or exterior margin much shorter than 



the posterior ; inferior wings lengthened horizontally, but short 



and rounded. Antennae slightly pectinated in one sex only : 



palpi pointing vertically. Inhabits Tropical America only. JVob,

Large: anterior wings black, with one basal, and two trans- 

 verse, opaque, deep yelloio hands ; posterior yellow, with a 

 broad black border; margins of both wings dotted with

We now, for the first time, detach from the moth-like, or 

 diurnal Sphinxes, all those large and imposing' species 

 which are found in Tropical America ; and by comparing 

 their characters with those of the Oriental group Helonia, 

 it will be seen how strikingly they differ. During our 

 researches in Brazil, the chief metropolis of this group, 

 great attention was paid to these insects, of which we have 

 a most extensive series. They lly slowly and heavily during 

 the middle of the day, and on the least touch counterfeit 

 death. Most of the species, when handled, discharge from 

 their body a brown liquor, like their prototypes the 

 Helicon id os. 



ANTHO M Y Z A heli collides, 

 Heliconian Burnet. 



Anterior wings black, ivith one basal and two transverse hyaline 

 yellowish white bands : posterior yellowish white, with a 

 broad black border, margins of both wings dotted with white. 



If we were not in possession of both sexes of the foregoing 

 species, we should have suspected that this was a mere 

 sexual difference; but the spots are transparent. The 

 remarkable resemblance between this and some of the 

 Heliconian butterflies, particularly Linus and Psidii, (Cr 

 pi 257.) is truly astonishing. Nature could not have 

 (stamped their analogy stronger.
