CALAIDES. 283 



It is brown, with large white blotches on the back, irregularly 

 marked with brown. The pupa is light brown, dotted with 

 blackish. 



[XLIII.] Troilides, Hiibner. The type of this genus is T. tor- 

 quatus (Cramer), a common South American Butterfly, 

 measuring from two and a half to three inches in expanse. In 

 the male the fore-wings are much shorter and broader than in 

 the last genus, and much less pointed, the hind-margin being 

 only slightly oblique. The hind-wings are much more strongly 

 dentated, the tail is shorter and more distinctly spatulate, and 

 the two projections between this and the anal angle are longer 

 than in Heraclides, more like two short tails. There is a very 

 broad pale yellow band running obliquely from the upper 

 median nervule of the fore-wings ; on the hind-wings it extends 

 nearly to the base. There is also a broad oblique sub-apical 

 pale yellow band on the fore-wings, and a row of sub-marginal 

 yellow lunules on the hind-wings ; the incisions are also yellow. 

 On the under side of the hind-wings there are rows of blue 

 lunules and red spots within the yellow lunules. The female is 

 brown, with a large white spot covering the basal half of the 

 lower median nervule. The hind-wings are strongly dentated 

 and tailed, with pink incisions, and a red band on the disc, 

 divided into spots by the nervures. 



[XLIV. B.] CalaidcS) Hiibner. The type is C. androgeus 

 (Cramer), a fine Butterfly common in Tropical America, which 

 measures over five inches in expanse. The fore wings are 

 long, but rounded off at the tip, and the hind-margin is oblique 

 and concave. The hind-wings are strongly dentated, and 

 have a moderately long tail, pointed (not spatulate) at the end 

 of the upper median nervule; and the other nervures on each 

 side of the tail exhibit well-marked, but shorter, projections. 

 A broad yellow band, commencing beyond the cell of the fore- 

 wings, runs obliquely across the wings, and on the hind-wings
