these insects being of very powerful and rapid flight. When at rest the wings are 

 extended horizontally. 



Mr. Watson divides the subfamily into twelve genera, and this division might be 

 carried further. Of the genera now established eight occur within our limits ; the 

 remaining four, which are unrepresented, are Mahotis, Ardaris, Mimoniades, and 

 Microceris— Mimoniades being the only one of any extent as regards the number of its 

 component species.

This genus, as restricted by Mr. Watson, is represented in Mexico and Central 

 America by twelve species belonging to most of the leading forms, including the more 

 typical, such as P. phidias, as well as some of the more aberrant, as P. wsculapius, 

 P. jonas, and P. erythrosticta. 



Pyrrhopyge belongs to the section of the subfamily in which the middle and lower 

 discocellulars of the primaries are very obliquely placed with reference to the axis of 

 the wing, and in this respect it differs from Oxynetra. The club of the antennae is much 

 thickened, the shaft also being stout. The secondaries have no radial nervure, the 

 second median segment of the primaries is about half as long again as the third 

 segment, and the lower discocellular of the secondaries meets the median beyond the 

 origin of the second median branch ; the upper discocellular of the primaries is very 

 short, and meets the subcostal at the origin of the fourth branch ; the second sub- 

 costal segment is longer than the third, and the third than the fourth. The hind 

 tibiae have a distinct fringe or mane of hairs springing from the dorsal edge. This last 

 character at once separates Pyrrhopyge from Mysoria, though not peculiar to Pyrrhopyge 

 alone.
