The specimen from Guatemala, from which our figure is taken, is much darker in 
colour than either of those from the State of Panama. It is quite possible that this 
insect may require a new genus for its reception ; but till more examples are obtained 
we prefer to place it provisionally in Orthogramma. O. lamida is apparently allied to 
the insect figured by Herrich-Schaffer under the name of Orthogramma dilina, Guén., - 
a species not mentioned in Guénée’s work. .

Walker, in his Catalogue, included in this genus a large number of species from all 
parts of the world; many of these have since proved to belong to distinct genera, and, 
doubtless, as the others become better known, still more will have to be eliminated 
from it. Several of the species are extremely common throughout Tropical America 
and the West-Indian Islands. Five are here enumerated from Central America.

This very common and widely-distributed species is found almost everywhere in 
Tropical America. It varies very considerably, both in colour and markings; but with
