26 THE ENTOMOLOGIST. 



species have two large eyes on the under side of the hind 

 wings, one on the middle of the costa and the other near the 

 anal angle. The larvae have generally bifid tails, and are 

 without spines. This subfamily is exclusively Tropical 

 American, and, along with the Morphince, includes the 

 largest of the American butterflies. They are robust insects, 

 and generally fly at twilight. 



The genus Brassolis (which was formerly placed alone in 

 the family Brassolidce, the remaining genera being referred 

 to the Morp/iidce) may be distinguished by its very small 

 palpi; and ihe larvae are destitute of an anal fork. The 

 thorax and abdomen are very robust, and the antennae are 

 also thick, with a gradually formed club, so that one of the 

 species has actually been mistaken for a Casdiia. There are 

 very few species known, all closely resembling the three old 

 species, Aslyra, Godt., Sophorce, Linn., and Macrosiris, 

 Westw. and Hew. The two first are about three inches and 

 a half across, dark brown, with a broad tawny band on the 

 fore wings, bifurcated on the cell, and running from thence 

 to the inner margin. In B. Asti/ra the costa is much more 

 strongly arched than in the other species ; and the hind 

 margin is slightly concave. B. Sopliora has a narrower and 

 redder submarginal band on the hind wings also. B. Macro- 

 siris is a very heavy-looking, purplish brown insect, with two 

 large round black spots surmounted by a smaller white one 

 near the tip of the fore wings ; and the apex of the hind wings, 

 and a short line running from the costa of the hind wings just 

 beyond the cell, are violet. 



The genus Opsiphanes includes a number of species, much 

 resembling Brassolis, but with broader wings and more 

 slender bodies. They are nearly all brown insects, with a 

 band, varying from buff to reddish orange, running from the 

 middle of the costa of the fore wings, where it is often 

 bifurcated, to the hinder angle, and generally a similar 

 submarginal band on the hind wings. In O. Syme, Hiibn., 

 the band is submarginal on the fore wings also, and there is 

 a shorter one within it; the hind wings of this species are 

 suffused with blue in the male. In O. Batea, Hiibn., all the 

 wings are taw iiy to beyond the middle ; and O. Boisduralii, 

 Westw. and Hew., is uniform tawny, with a dull brown spot 

 near the tip of the fore wings. Dynastnr Napoleon, Westw. 

 and Hew., is an immense brown butterfly, with narrower fore 

 wings and thicker body than Opsiphanes ; it expands about 

 seven inches. There is an interrupted pale yellow band
