Descriptions o£ a new G-enus and of some new Species of 
Gcilerucince , also Diagnostic Notes on some of the older 
described Species of Awlacophora. By Joseph S. Balt,

[Read 6th May, 1886.] 
Many of the insects characterized in the following paper were 
collected in the Eastern Archipelago by Mr. A. B. Wallace. 
Types of all the species mentioned are contained in my col- 
lection. 
G-enus Aulacophora. 
Many of the species of this genus, more especially those 
described by the older authors, are in a state of great confusion, 
arising to some extent from the great similarity in general 
appearance and coloration of many of them ; but principally 
from the brief descriptions given by the various authors and from 
the total absence of any reference to structural characters. 
In the present paper I have attempted to work out some of 
these species, pointing out the structural characters by which 
they may be separated. I have retained, iu most cases, the old 
names, although I cannot be sure in every instance that the 
species to which they are assigned were those from which the 
descriptions were originally drawn. 
I have not attempted to work out the whole genus, many 
species sufficiently characterized by their respective describers, as
