and antenne brown; the first article of the latter of a 
lighter colour ; tarsi brown.

Note.—This sort has entirely the form of Gracilis, but 
is distinct by its much larger size and its black legs... 
Promecoderus Howittis : length 7’; very nearly allied to 
Brumcornis, having the same form, but the elytra are 
smooth, and have only a sutural stria. This sort is common 
round Melbourne. I have preserved the name given to it 
by the late Mr. MacLeay in his collection. It is distin- 
guished from Concolor by the presence of the sutural strie, 
and from Sutwralis by the color, which is generally dull, by 
its form, much thicker, and the elytra more rounded behind. 
From Melbourne. 
Promecoderus Wilcoxw: length 116%’; copper colour; head 
with two large rounded impressions in’ front and two punc- 
tiform ones between the eyes; thorax globular, with a 
strong longitudinal sulcate in the middle, and two feeble 
transverse impressions, one in front and the other behind ; 
elytra oval, with strong striz, which become very weak 
towards the margin; these striz appear punctated when 
seen through a magnifying power; on the posterior part of 
the margin are three impressions, two being punctiform, and 
one linear ; lower side of the body of a green copper colour ; 
seoments of the abdomen with a punctiform impression on 
each side ; legs of a dark brown, antenne, tarsi, and buccal 
parts of a ‘light reddish brown. 
Sent by Mr. Wilcox from the Clarence River. 
Promecoderus Lucidicollis : length 547; of a shiny black ; 
head and thorax of a brilliant copper colour, the latter rather 
short and globiform, with the longitudinal sulcate, and the 
anterior and posterior transverse impressions strong ; elytra 
oval, smooth, with three large impressions on the posterior 
part of the margin; sides of the abdominal segments very 
strongly impressed ; eos, antenne, and parts of the mouth 
of a reddish brown. 
Melbourne. 
This insect, by the absence of all striz on the elytra can 
only be mistaken for Concolor or Gracilis. It is distinct 
from the first by its much smaller size, its thorax shorter 
and more gibbous, the colour of its legs, &e.; and from 
the second by the oval form of its elytra, which are oblong, 
and rather parallel in Gracilis. In form it resembles 
Bassit.
