Guenee’s type was from Montevideo. Northwards the 
species reaches as far as the West Indies and Mexico. 
Warren’s B. tenuimargo, from Brazil, is the same species 
(sec. specim. typ.).

Previously only known from Chili (i); the series from 
which Butler described was collected at Las Zorras by 
Mr. T. Edmonds ; Izquierdo, An. Univ. Chile, liii, 815, 
says it ranges from Aconcagua to the interior of Araucania. 
The species is interesting as being the only member of the 
sub-family yet discovered in Chili. It does not seem to 
be very closely related to any known species, yet the 
following short but interesting account of the early stages, 
translated from Izquierdo, shows clearly the Heinitheine 
characteristic. 
Larva on [Duvarct] Sehmiis dependens DC., reache.s, when full- 
grown, a length of 18 mm., thickness H mm. Uniform green, of 
the same colour as the leaves of the food-plant; dorsal area reddish 
in some examples. Bears an extraordinary resemblance to a little 
twig. When taken between the fingers it feels decidedly hard, more 
so than any other larva of like size known to the writer. In the 
medio-dorsal line there is a series of intersegmental dots of a dark 
coffee-colour. The anterior extremity of the larva terminates in two 
small sharp horns with reddish spots, which simulate to perfection 
the little buds of a twig. These, horns are appendages of the head, 
and this latter, in repose, is bent downwards and closed up so tightly 
with the legs that it is impossible to distinguish them. Laterally 
the body has a very fine, conspicuous yellow line, which terminates 
in the horns of the head. Pupates among leaves without making a 
cocoon. The pupa, green at first, becomes nearly white, and two or 
three days before emergence, the wing-cases assume a dark green
