NEW SPECIES OF AUSTRALIAN COLEOPTERA, 
There is in the Macleay Museum a male — also from the North- 
West — which differs from the above (of which I have three males 
under examination agreeing in all particulars) in having the 
antennae, except base, the femora, except apex, and all the tarsi 
brown; the antennae appear to be shorter, and the head less deeply 
sculptured; possibly it is a distinct species, but at present I can 
only regard it as a variety. 
Helcogaster fuscitarsis, n.sp. 
(J. Elongate, shining, depressed. Black; head, except base, 
four basal joints of antennae and undersurface of 5th, apical half 
of anterior and two-thirds of four posterior femora, tibiae, and 
base of tarsi, testaceous; shoulders very feebly diluted with 
testaceous. Above with sparse and moderately long blackish 
hairs, elytra and abdomen with sparse short and obscure greyish 
pubescence. Head and elytra densely, very minutely and obso- 
letely punctate. 
Head longer than wide; eyes moderately large; a deep and 
somewhat circular excavation in front, commencing a little behind 
the eyes, its sides from in front of the eyes marked by a slight 
carina, which between the antennae is directed backward and 
terminates in a feeble tubercle in the middle; base, sides and 
undersurface feebly corrugated; foveae rather large, round, rough- 
walled, approximate; antennae almost reaching posterior coxae, 
feebly thickest in the middle, the two apical joints equal in 
length. Prothorax a little longer than wide, not the width of 
head; a broad shallow impression at base; base narrowly mar- 
gined. Elytra about one and a quarter times as long as head and 
prothorax combined, at base decidedly wider than head, increasing 
to apex, each separately rounded internally, and obliquely truncate 
externally. Basal joint of anterior tarsi not very large. Length 
to apex of elytra 24. of abdomen 4; width l|mm.

Helcogaster brachypterus, Boh em.; Mast. Cat. Sp. No. 344L 
Only the male of this species has been described; the female 
differs in having the head narrower and entirely black, the pro-
