I owe my single specimen of this brightly coloured species to 

 the generosity of Mr. A. M. Lea. It most resembles C. dispar 

 Mad, but differs by elytra without discal punctures: marginal 

 border and channel of prothorax and elytra narrower; elytra 

 more convex, side-border of base less divergent to tlie humeral 

 angles; elytra of a beautiful shining blue. Fiom C. macleayi 

 Blkb., it differs by head with anterior angles (preocular pro- 

 cesses) rounded, not prominent; prothorax much less narrowed 

 anteriorly; elytra narrower, more convex, base narrower, more 

 abrupt, side-borders far less divergent to humeral angles. 



Note. — There is no trace of the usual setigerous punctures in 

 the lateral channels of the prothorax in the specimen before me. 



Carenum blackburni, n.sp. 



Oblong-oval, convex, Isevigate. Head with one supraorbital 

 puncture on each side; prothorax transverse, anterior angles 

 strongly porrect, posterior angles widely reflexed, obtuse, but 

 marked, base lobate; elytra bipunctate towards apex, humeral 

 angles prominent, anterior tibipe 3-dentate. Black, polished; 

 marginal channel of prothorax and elytra obscurely violaceous. 



Head large (5-2 mm. across eyes), convex on occiput; frontal 

 sulci deep, parallel; median frontal space convex; lateral frontal 

 spaces abruptly declivous externally; clypeus with median part 

 truncate, intermediate angles widely and obtusely triangular; 

 preocular sulcus distinct, short; preocular process small; eyes a 

 little convex, not prominent. Prothorax convex, transverse 

 (415 X 7 mm.), about equally wide at posterior and anterior 

 angles; sides subparallel, a little narrowed anteriorly; anterioi- 

 angles prominent, but obtuse; posterior angles rounded, but 

 marked; base decidedly lobate; border narrow in middle of sides.
