The well-known North-American E. tityrus (Fabr.) is the type of this genus, with 

 which are now associated fourteen or fifteen other species, all of them from the 

 Neotropical region. Two species of wide range in Tropical America occur within our 

 limits ; a third, E. gaumeri (a race of E. exadeus), is found in the island of Ruatan. 



The following characters, according to Mr. Watson, define Epargyreus: — The 

 secondaries have no tail but only a projecting tooth at the end of the submedian 

 nervure ; the antennae are distinctly hooked ; the hind tibiae have two pairs of spurs ; 

 the lower discocellular of the primaries is straight ; no tufts of hair on either wing ; 

 male with a costal fold to the primaries; second median branch of the secondaries 

 emitted some way before the end of the cell. 



Besides these points the following may also be noted : — The palpi are densely scaled, 

 so that the tips of the terminal joints are only just visible ; the upper discocellular is 

 very short, the middle and lower discocellulars are in a straight line and subequal ; 

 the third median segment is long, being considerably more than half the second, and 

 the recurrent nervule starts from nearer its proximal than its distal end.
