rugulose punctures. Basal joint of front tarsi lopsided, with a 

 small, black, apical comb. Length, 2'25-2'5 mm. 



Hab.—'New South Wales: Grenfell (Dr. E. W. Fer- 

 guson). Type, I. 11924. 



The flat space near each eye is densely punctate, but from 

 some directions appears finely granulate; as there is a distinct 

 fovea in the middle of the head the species might be referred 

 to FF of my table, but the head is very different from all the 

 species there noted ; the species, however, is allied to H . 

 foveiceps, but the head is differently sculptured, and elytra 

 bicolorous. //. centralis has the fovea closed posteriorly and 

 the front of the head with a large, obtuse tubercle, its pro- 

 thorax is also of different shape, and elytra of one colour. 

 The elytra, are coloured somewhat as in H. impera-tor, but 

 the head and prothorax are very different. The flavous parts 

 are the head (except at extreme base), prothorax, legs (except 

 coxae and base of femora), and three or four basal joints of 

 antennae; part of the side of each elytron is of a different 

 shade of flavous to the prothorax, the black part commences 

 at the base (near to but not touching the sides), is rapidly 

 narrowed towards the suture, and then continued along it to 

 beyond the middle, when it is suddenly dilated to cover the 

 apical two-fifths. On the type the apical joint of antennae 

 is almost as pale as the basal ones, on a second male the 

 apical joint is scarcely paler than the tenth, and the middle 

 and hind tibiae and tarsi are slightly infuscated. 



Helcogaster pallidus, n. sp. 



o . Flavous ; metasternum and six apical joints of 

 antennae deeply infuscated, middle of elytra slightly infus- 

 cated. With rather sparse, pale pubescence, a few darker 

 hairs on sides. 



Head not very large, with a large obtuse median eleva- 

 tion; punctures dense and irregularly distributed, becoming 

 confluent about base. Eyes rather larger than usual. 

 Antennae long, thin, and scarcely serrated. Prothorax dis- 

 tinctly transverse, apex much wider than base, a wide and 

 rather deep closed subbasal depression ; punctures small and 

 sparse. Elytra rather long; with fairly dense, minute, rugu- 

 lose punctures. Legs long and thin, basal joint of front tarsi 

 with a small, black, apical comb. Length ( S , 9 )> 2'25-3 mm. 



9 • Differs in having the head smaller, nontuberculate, 

 two shallow impressions in front, and with sparser punctures, 

 antennae thinner and scarcely infuscated towards apex, pro- 

 thorax less dilated in front, tip of abdomen infuscated, and 

 legs shorter, with combless tarsi.
