TELEMIADES. — DYSCOPHELLUS. 319 



The types of this species are said to have come from the West Indies, bat were pro- 

 bably from the northern part of the South- American continent, whence we have a series 

 of specimens agreeing well with Geyer's excellent figure 1 . From these our Mexican 

 and Central-American examples show no tangible differences. Some variation is 

 observable in the hyaline spots of the primaries, the costal spot is occasionally wholly 

 wanting, and the subapical spots are sometimes nearly equal in size instead of the 

 middle one being the smallest. 



The male genitalia resemble those of T. avitus, but the harpes are more rounded and 

 the recurved spine shorter.

This genus was based upon Cramer's Papilio sebaldus, of which P. crameri, Latr., is 

 the female, a South-American insect, the only congeneric species known to us being 

 Dyscophellus doriscus, which occurs in the State of Panama. 



The antennae in Dyscophellus have the terminal attenuated portion of the club not 

 longer than the remaining part of it ; the outer and inner margins of the primaries are 

 subequal ; the cell of the primaries is more than two-thirds the length of the costa, 

 the middle discocellular is shorter than the lower and makes an obtuse angle with it, 

 the second median segment is about three times as long as the third, and there is a 

 recurrent nervule from the distal end of the latter; the discocellulars of the secondaries 

 form a convex curve, and the lower discocellular meets the median a little beyond the 

 second branch, the radial is faintly developed. 



The palpi of this and the two following genera have a short nearly erect terminal 

 joint, which just appears beyond the dense scales of the second joint. All three genera 

 have a costal fold to the primaries of the males.
