138 Notes on Australian Coleoptera. 
Carenum Atronitens (MacLeay, jun., “Transactions Ent. 
Soe. of N.S. Wales”): length 114’; of a brownish black ; 
general form long and elongated, with the sides parallel; 
head with two longitudinal impressions between the eyes ; 
they are sinuous, and diverge in front towards the anterior 
angles of the head ; thorax longer than broad, margimated 
all round, emarginated in front, with the sides parallel ; 
the posterior angles are rounded, and the posterior side is 
rounded and rather sinuous in its centre. There is a longi- 
tudinal sulcate in the centre, and transversal impressions in 
front and behind ; an impression is visible on the anterior 
angles ; elytra long, same breadth as the thorax, sub- 
parallel, marginated laterally ; their base is emarginated, and 
the axillary angles prominent ; their surface is smooth to 
the eye, but presenting a few very faint longitudinal ele- 
vated lines when seen witha magnifying power; they have each 
two faint punctiform impressions, one behind the axillary 
angle, and the other at their posterior part ; anterior legs 
armed with two very strong teeth. 
This insect comes from Gawler, in South Australia. I 
believe it to be the <Atronitens (Macleay, jun.), but the 
description does not exatly agree with it. 
NEOCARENUM. 
Mentum armed in its centre with a long, acute, and cari- 
nated spiniform tooth; its wings very long, advanced, 
narrow, arched, and rounded at the end; _ palpi— 
the maxillary ended by one article, long, narrow, 
arched, and rounded at its extremity ; the same of the 
labial, rather longer than the preceding, conical, but rather, 
arched ; maxille rather narrow, arched, and densely hirsute 
internally ; mandibule strong, arched, pointed at the ex- 
tremity, and armed on their internal side with several strong 
teeth ; labrum short, and having several denticulations ; 
antenne short, strong, getting thicker as they go towards 
their extremity ; the two first articles are strong and 
conical, the third also, but rather shorter, the others almost 
round, not compressed, the last rather pointed ; body 
long, cylindrical, filiform ; head almost square ; thorax longer 
than broad, joined with the body by a pedoncule, on which 
is situated the scutellum ; elytra long, parallel ; legs rather 
short ; thighs inflated ; anterior tibize palated ; those of the 
other pairs crenulated on their internal margin. 
This singular genus, in some respects, unites Carenwmn with
