structural points. The % antenna are not provided with the expanded 

 scape, and do not differ from those of P. 31'hheimerii. The abdomen, 

 while exceeding the hind wings, is unprovided with the long, parallel, 

 porrected, hirsute processes, described as characterizing the male of P. 

 BateslL The coloration also differs. 



It is interesting to find this genus represented in Cuba by a distinct 

 species. The representation of the sub-family is structurally very in- 

 teresting, since it contains four species, belonging to so many different 

 genera. From a study of the excellent figures given in the anonymous 

 work on the Lepidoptere of Surinam, I see that the ^'- Bomhyx vorax'' 

 of this unknown author, represents a species allied to Perophora , and 

 belonging to the present Sub-family. 



I have named the Cuban Perophora after A. S. Packard, Jr., M. 

 D., whose recent papers on the Bombycidte of the United States have 

 added greatly to our proper appreciation of the most interesting Family 

 of the Sub-Order. ^ ■

Allied to H. obliqua Packard, but a more brownish species, wanting 

 the white sub-apical patch and the greenish shade of the upper surface 

 of the primaries which characterize our Northern species. The speci- 

 mens, however, appear to be faded, and the greenish shades in this 

 genus seem easily lost by age and etiolation. A geminate irregular 

 sub-basal line. The costa is marked by alternate darker and paler 

 streaks. Median lines outwardly arcuated, joining below at the middle 

 of the wing, a long cuned interspaceal black dash which is bordered 

 above by a paler shade ; a similar paler shade beyond the median line 

 above internal margin. This latter shade is bounded outwardly by a 

 faint liue, which appears to be discontinued above the linear black in- 

 terspaceal dash. Indistinct lines beyond the disc, discontinued above 

 the interspaceal dash. An arcuated, black, sub-apical line, joining a 

 very narrow streak in the interspace above the first m. nervule. A 

 sub-terminal shade band and narrow terminal line. In the male the 

 ornamentation is sub-obsolete. Secondaries whitish, dusted with brown- 

 ish scales. Under surface of primaries brownish. Head and thorax 

 brownish, tegulae with internal dark marginal lines uniting in front. 

 Abdomen, pale brownish. Antennaa shorter than in //. obliqua, the 

 basal pectinations in the male not extending so far from the antennal
