DESCRIPTIONS OF TWO NEW SPECIES OF CARENUM 

 FROM WEST AUSTRALIA, WITH NOTES ON THE 

 SYNONYMY AND DISTRIBUTION OF SOME PRE- 

 VIOUSLY DESCRIBED SPECIES. 



By Thomas G. Sloane. 



In the following paper I describe two new species of Carennm 

 from West Australia, which I have received from Mr. C. French 

 of Melbourne as coming from between York and Yilgarn Gold- 

 field. I also take the present opportunity to publish some 

 information I have collected with regard to the synonymy and 

 distribution of a few previously described species. I had hoped 

 to have treated of the synonymy of the whole group of Carenides 

 before long, but pressure of business and absence from Sydney 

 have compelled me to relinquish the idea ; and I now offer these 

 notes merely as a contribution towards the elucidation of the 

 synonymy of the group, which can only be undertaken in Sydney 

 by a careful study of the Macleay Collection. 



Carenum ignotus, n.sp. 



Form elongate. Black, shining, (upper surface of head and pro- 

 thorax dull in my specimen), elytra with a very narrow and faint 

 edge of cerulean hue. Head subquadrate (4 x 4 J mm.), depressed ; 

 frontal sulci short, curved, not connected behind, almost parallel 

 backwards, and extending forwards in full depth towards base of 

 mandibles ; preocular process prominent ; eyes not prominent ; 

 two supra-orbital punctures on each side ; antennae moniliform, 

 not tapering, last joint short and obtuse. Prothorax broader than 

 long (5 x 6 \ mm.), smooth, subconvex, declivous behind ; anterior 

 angles rounded, not advanced ; sides parallel in front of the
