244 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 feebty corrugated; foveae rather large, round, rough- 

 walled, approximate; antenme 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 narrow^ 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 21-. of abdomen 4; width 1 J mm. 



Hah. — Sydney. 



Helcogaster brachypterus, Bohem.; Mast. Cat. Sp. No. 3441. 



Only the male of this species has been described; the female 

 differs in having the head narrower and entirely black, the pro-
