188 Mr. C. J. Gahan’s notes on the 
represented in the British Museum collection by examples 
from each of the following localities :— West Australia, 
South Australia, Queensland, North Australia, Murray 
Island, Cornwallis Island, and New Guinea. 
The males vary considerably in size; the smaller 
examples having a length of only 12 mm., the larger 
attaining a length of 23 mm. In the smaller males the 
antenne are very short, scarcely surpassing the body in 
length, and their terminal joint is but little longer than 
the tenth; while in the largest males the antenne are 
about twice as long as the body, with the last joint about 
twice as long as the third. 
The markings on the elytra are somewhat variable. 
The anterior black plaga of each elytron may be alto- 
gether wanting (this is the case with a female specimen 
from Queensland), it may be entirely surrounded by 
fulvous, or may have extended inwards to border the 
suture, or, as in some of the larger male examples, the 
black may have extended over nearly the whole elytron, 
leaving fulvous only a basal spot at the side of the 
scutellum, a sutural spot a little behind the middle, and 
a marginal band, dilated at the shoulder and at its 
hinder extremity near the beginning of the posterior 
third.
