206 ON THE CARE^UDES (FAM. CARABID^E), 



gatum, but is more convex, and has the elytra suffused with 

 purple. 



Carbnum subporcatulum, Macl. 



I found this species at Finche's Creek, 40 miles from Dalby in 

 the Darling Downs District, Queensland; and have compared my 

 specimens with the type specimens of C. subporcatulum. It is a 

 l?evigate species; the sculpture of the elytra alluded to in the 

 original description may be looked upon as a post mortem effect 

 caused by submersion in alcohol; the prothorax and elytra become 

 violaceous near the sides of the disc, the margins being pale blue. 



Carenum POLiTULUM, Macl. 



The description of this species reads as if founded on specimens 

 of C. subporcatulum; it requires further examination. 



Carenum carbonarium, Castelnau. 



The description of this species seems to be founded on a species 

 closely allied to C. vicinum, SI. It is possible the difference in 

 colour may be only a variation, and that these species are 

 synonymous, but specimens from Esperance Bay will have to be 

 examined before this can be settled. 



Carenum imitator, n.sp. 



Elliptical-oval, robust, Isevigate; elytra bipunctate posteriorly, 

 inflexed margins wide; anterior tibise bidentate. Black, shining; 

 prothorax and elytra margined with green — a green tinge 

 pervading all the lateral declivities of elytra. 



Head large, transverse (3'7 x 6 mm.), subdepressed ; frontal 

 sulci deep, diverging backwards and curving outwards to define 

 posterior margins of spaces between frontal sulci and eyes, their 

 anterior part curving outwards in a deeply marked course ; 

 spaces between frontal sulci and eyes very convex ; preocular 

 sulcus deep, wide; two widely placed supraorbital punctures on 

 each side. Prothorax transverse (5-5 x 7'9 mm.), convex; sides 

 rounded; basal curve subrotundate (trisinuate); anterior margin 

 emarginate ; anterior angles widely and decidedly advanced ;
