minent humeral angles. The posterior marginal puncture of the 

 prothorax is placed a little before the posterior angle, which is ;xn 

 unusual position in Carenum. 



Carenum ovale, n.sp. 



Elliptical-oval, robust, convex, leevigate ; head large, with 

 parallel frontal sulci ; prothorax transverse, posterior angles 

 rounded; elytra oval, bipunctate posteriorly, humeral angles not 

 marked; anterior tibiae tridentate. Black, prothorax and elytra 

 with narrow violaceous margins. 



Head transversely subquadrate (4-6 x 6-8 mm.), convex; frontal 

 sulci short, parallel; clypeus lightly declivous to labrum, median 

 part wide, truncate, intermediate angles short, obtuse ; eyes 

 convex. Prothorax transverse (5 x 8-5 mm.), convex; sides 

 lightly rounded, subparallel in middle, rounded at posterior angles; 

 basal curve short, lightly bisinuate ; anterior margin truncate 

 between anterior angles — these shortly advanced, obtuse; border 

 thick, reflexed, more widely upturned at posterior angles; two 

 marginal punctures on each side. Elytra oval (12'6 x 9-2 mm.), 

 convex, roundly declivous to humeral angles; sides evenly rounded; 

 base roundly truncate; humeral angles rounded; border reflexed, 

 hardly folded over (not thickened or upturned) at humeral angles; 

 marginal channel wide; five or six punctures in two rows near 

 humeral angles ; the punctures along mai-gin small and closely 

 placed. Presternum not bordered along anterior margin; inter-

Ifab. — Queensland : Win ton District (Coll. French). 



Allied to C. dispar, Macl., from which it is readily identified 

 by colour; more convex shape; the elytra with base not wide and 

 truncate, and with shoulders rounded, the border not thickened 

 and folded back at humeral angles; the base of the prothorax less 

 strongly lobate, &c. It is readily differentiated from C. interioris,
