[Read July 2, 1895.] 
The interesting collection of Carabide made by Mr. A. Zietz, 
of the Adelaide Museum, at Lake Callabonna in September, 
1893, has been placed in my hands for examination; and I 
offer the following notes as the result of my investigation of the 
thirty-seven species contained therein. The types of the new 
species belong to the Adelaide Museum. 
NEOcCARENUM BLACKBURNI, 2. sp. 
Elongate, robust, parallel, convex ; prothorax a little wider 
than long, widely rounded behind ; elytra convex, smooth, im- 
punctate, base deeply emarginate ; anterior tibize bidentate ; in- 
termediate tibize strongly bidentate externally. Black. 
Head large, transverse (4°5 x 6:5 mm.), lightly convex, smooth, 
transversely impressed across occiput; frontal sulci deeply im- 
pressed, strongly curved, diverging greatly backwards, anterior 
part of their course very lightly marked, and not reaching margin 
of head; space between frontal sulci wide, not elevated; pre-ocular 
sulcus widening into a broad depression anteriorly ; pre-ocular 
process forming a strong triangular projection ; eyes deeply en- 
closed in orbits ; lower edge of orbit thick, and forming a ridge 
below posterior part of eye; suborbital channel (to receive an- 
tenn) oblique, very deep, distant from eye; two supra-orbital 
punctures on each side placed close together at base of space 
between frontal sulci and eyes; genz (between suborbital 
channel and buccal fissure) divided from submentum, striate. 
Labrum with anterior margin rounded and advanced in middle. 
Labial palpi with last joint widely securiform. Antenne thick, 
moniliform, incrassate ; joints 5-11 compressed, grooved on edges, 
second joint very little longer than third. Prothorax a little 
broader than long (7‘7 x 8 mm.), widest a little behind anterior 
angles, lightly convex, not declivous behind; sides almost 
parallel between marginal punctures, a little narrowed to base 
behind posterior marginal puncture ; anterior margin truncate ; 
base wide, evenly and lightly rounded; anterior angles widely 
rounded, not marked; posterior angles very obtuse, lightly
