The characteristics of the Amatnustinn, as above defined, we consider amply 
distinctive for justifying their entire separation from the true Morpuin”, with which 
they have hitherto been mostly included, and have therefore adopted the oldest 
generic name for their designation. 
In the Brassouina, the American allied sub-family, the forewing, in all the 
known genera, has both the first and second subcostals free, and the third subcostal 
three-branched ; the hindwing also having a prediscoidal cell; the antenne being 
long, and in Opsiphanes with a stout club. Im the genus Caligo, the males are 
furnished with secondary sexual characters, the hindwing of the male of C. Amphi- 
medon possessing a glandular-tufted pouch along the base of the submedian vein, and 
it also has a large prominent glandular patch of scales near the end of this vein, 
besides also having a glandular patch of scales on the side of the abdomen. In the 
genus Opsiphanes, the hindwing of the male of O. Xanthus and O. Cassi possesses 
a subcostal glandular tuft, and a tufted pouch along the submedian vein, in addition 
to a glandular patch of scales on the side of the abdomen. The larve of the Brasso- 
line are elongate, thickest about the middle, minutely hairy, or nearly nude, the head 
being furnished with two lengthened spiny processes on the vertex, and two or three 
shorter lateral processes, and the anal segment with two elongated fleshy processes. 
The pup are somewhat stout, the thorax broad and truncate in front, the head-piece 
with two short widely separated points.
