disc, deeply declivous on sides, strongly declivous on apex, trun- 

 cate on base (lightly subemarginate); basal declivity deep and 

 abrupt ; sides subparallel, lightly rounded; lateral border wide, 

 reflexed on anterior half, thick posteriorly, thickened and forming 

 a short erect prominence at humeral angles; a row of separate 

 ocellate punctures along the shallow marginal channel; a row of 

 three or four punctures on outer side of base of each elytron; 

 suture deeply impressed. Legs light; posterior trochanters acute 

 at apex, impunctate; anterior femora rather long, not very wide 

 or compressed, lightly channelled below; posterior femora with 

 lower side roundly subangulate and punctate at apex of trochan- 

 ters; anterior tibise as in C. scaritioides, Westw. 



Length 21, breadth 5-8 mm. 



Hah. — West Australia (Coll. French). 



A very distinct species; the only described species to which it 

 is closely allied is C. batesi, Masters (C. planipenne, Bates), with 

 which it seems to agree in every character of structural import- 

 ance, but C. batesi is described by Mr. Bates as being " olive-black 

 with the margixis of' the thorax and the vrhole elytra clear green," 

 and having the elytra "retuse at the base." I should not call the 

 elytra of C. vemistum retuse at the base, the top of the basal 

 declivity being a gentle concave curve between the humeral 

 angles, and I think C. batesi must be a species with the dorsal 

 surface flattened as much as C. pulchrum, SI. After seeing C. 

 venustmn, it becomes evident to me that Sir William Macleay 

 was wrong in putting C. batesi in his ^'' marginatum-gTou\)" of 

 species, to which it seems to have no aflinity; it should be placed 

 with C. venustuin in the same group as C sutnptuosum, Westw., 

 and C. quadrijnmctatum, MacL; this group will therefore require 

 to be modified in regard to the number of discoidal punctures on 

 the el3'tra. 



Carenum acutipes, n.sp. 



Robust, convex, parallel, elongate ; head large, suborbital 

 channels obliquely divided by a strong ridge; prothorax hardly , 

 broader than long ; elytra oval, humeral angles subdentate/
