Sterboderus Macleayi, n.sp. 



Cylindrical, highly polished, glabrous. Black, antennje piceous- 

 red. Head and rostrum almost impunctate, mouth parts with 

 long reddish hair, prothorax with sparse distinct punctures, 

 sparsest towards base; elytra with regular rows of small distinct 

 punctures, interstices flat, not punctate. 



Head large, thick; eyes lateral, indistinct, a very feeble impres- 

 sion between them; rostrum very short, wider than long, antennte 

 inserted about middle of rostrum, scape very short, widening to 

 apex, feebly curved. Prothorax about once and one-third as 

 long as wide, feebly constricted near apex, which is slightly 

 emarginate at its middle, and almost as wide as base. Scutellum 

 distinct, subquadrate, within a depression. Elytra parallel to 

 near apex, with an indistinct sutural stria. Intermediate 

 segments of abdomen short, their sutures deep and wide. Legs 

 very short, tibije strongly fossorial. Length 4|, rostrum ^; 

 width H, rostrum | mm. 



Hab. — Cairns, N.Q. (Macleay Museum). 



Except for the shape of the prothorax this species agrees with 

 Mr. WoUaston's diagnosis of the genus Stereoderus; the base of 

 the rostrum has three small tubercles immediately behind the 

 long reddish hair with which the mouth is fringed. 



COSSONUS INTEGRICOLLIS, n.sp. 



Broad, depressed, feebly shining. Head and prothorax black, 

 elytra and scutellum dull brownish-red, the former tinged with 

 piceous towards apex; under surface, legs and antennae piceous- 

 brown. Rostrum with dense small punctures, prothorax with 

 large regular punctures except at apex where they ai"e .smaller, 

 each elytron with about twelve rows of large, subquadrate 

 punctures; interstices scarcely visibly punctate, about as wide as 

 punctures; under surface densely punctate, punctures of sterna 

 (especiall}'^ of pro- and mesosternum) stronger.
