8. Ithomia cayana. 



^ . Exp. 2*05 in. Antenna? moderately long, black ; palpi 

 Avhite, hUick anteriorly ; head black, with a white frontal spot ; 

 prothorax black, with a yellow spot on each side ; thorax black, 

 with a yellowish central streak ; abdomen black above, yellow 

 beneath : anterior wings semidiaphanous, brown, cell almost 

 to the end tawny ; an irregular pale yellow spot extends al- 

 most fr(jm the costa over the upper discocellular nervure and 

 the comer of the cell, and thence over the third median branch ; 

 between the first and second median branch is another smaller 

 yellowish spot ; these yellow spots leave an irregular dark 

 band, which crosses the end of the cell to the posterior angle : 

 posterior wings tawny; a semidiaphanous brown band crosses 

 the wing, and another skirts the outer margin : beneath as 

 above ; base of the costa of the fore wing tawny, seven con- 

 spicuous submarginal white spots siuround the outer margin, 

 and show through to the upper surface : on the hind wing 

 there are five similar spots : nem'ation of the hind wing some- 

 what as in Ith. antisao, Bates ; the lower discocellular is 

 straight, middle discocellular bent at the emission of the recur- 

 rent nervule, and then curved outwardly to the subcostal ; 

 upper discocellular absent ; upper radial starts as a branch of 

 the subcostal a little beyond the end of the cell. 



$ . Like the male ; nor does the neuration of the posterior 

 wing differ materially, the only distinction being that the 

 middle discocellular meets the subcostal at a more acute angle 

 and at a shorter distance from the base of the wing.

Obs. This species seems to have been overlooked amongst 

 specimens of Ith. sehnej Cr., to which it bears a great resem- 

 blance. The distinct row of white spots at once distinguishes 

 the species, and a comparison of the neuration shows that the 

 two are perfectly distinct, and do not even belong to the same 

 section of the genus. Ithomia cayana is quite common in 

 cabinets, having been sent in considerable numbers in recent 

 collections from Cayenne. Its nearest structural allies are 

 Ith. antisao, Bates, and its affines which have the upper radial 

 as a branch of the subcostal of the hind wing. 1 he present 

 species, however, differs in that the middle discocellular bears 

 the recurrent nerATilc instead of the lower.
