Hah. — ^Murchison District, W.A. (In the collection of Mr. C. 

 French.) 



It resembles C. habitans, 81., but differs conspicuously fi*om that 

 species in having the posterior tibiaj light, instead of thick and 

 incrassate ; the frontal sulci, too, are more divergent behind ; 

 there are two setigerous punctures above each eye instead of one, 

 four setigerous punctures in the marginal channel of the pro- 

 thorax instead of two, and the elytra are more rounded on the 

 sides. Its place is with C. elega7is* MacL, C. odewahnii, Casteln., 

 and C. speciosum, SI.; the slender posterior tibia? and the anterior 

 angles of the prothorax hardly advanced are sufficient to separate 

 it from the two last of these ; while the colour, and the more 

 evenly oval elytra more obtuse at the apex are among the features 

 distinguishing it from C. elegmis. The specimen before me has 

 the elyti-a covered with rows of very distinct punctures ; but I 

 have no doubt this is caused by long immersion in spirits of wine, 

 and that the elytra are naturally smooth. 



CaRENUiM COGNATUiM, n.sp. 



Elliptic-oval, robust, convex, Itevigate ; prothorax transverse, 

 anterior angles porrect, posterior widely rounded, base shortly 

 lobate ; elytra oval, bipunctate, inflexed margins wide ; anterior 

 tibiae tridentate. 



Head, legs and under-surface black ; prothorax widely margined 

 with green, disc black in middle (including anterior margin) with 

 purple reflections towards sides ; elytra deep purple margined with 

 green. Head subquadrate, transverse (3 -9 x 6 mm.), lightly 

 transversely impressed behind frontal sulci ; front depressed ; sulci 

 deep, diverging strongly backwards, turning sharply outwards in 

 front in a short lightly marked course ; pre-ocular sulcus light ; 

 pre-ocular process weakly developed ; eyes convex, projecting but 

 not prominent ; two supra-orbital punctures on each side. Pro- 

 thorax widely transverse (4-8 x 8 mm.), convex, declivous to 



* I cannot separate C. campeMre, Macl., from C. ehgam, Macl., and now 

 regard it as a synonym of C. elegans.
