Australian Cistelidae 95 



except armatus, in its Btrong pubescent clothing, but being much 

 mutilated it is inadvisable to describe it. It differs, moreover, from 

 armatus in its densely punctate upper surface. 



Scaletomerus bicolor, n. sp.

 tennae and tarsi black, elytra and legs testaceous, abdomen piceous. 

 Head wrv finely and closely punctate, eyes moderately large, not 



prominent, widely separated, antennae short and stout, joints 4-11 

 successively shorter than preceding, and oval (submonite form).

Two specimens (types) in the Macleay Museum differ from the de- 

 scribed species markedly in colour, the more narrowed prothorax, 

 and the stouter antennae.

4 Alternate intervals carinate, irregularly interrupted 



carinatus, Haag 



This genus consists of Otiorrhyncus-like insects, with ovoid pro- 

 thorax and elytra, the latter wider than the former. 1 have 

 examined specimens of S. Goddeffroyi, Haag., from Peak Downs, 

 Townsville, and other parts of Queensland, of carinatus, Haag., 

 from Port Darwin. 



Si mar us elongatus, n. sp. 



Elongate, elliptic, dark brown, thickly clad with short reddish 

 bristles, oral organs and tarsi red, antennae fuscous. Head and 

 prothorax closely granulose, the sculpture (of head especially) often 

 concealed by the hairy clothing. Eyes large and widely separated.
