of the truncature well-marked. The eyes are somewhat 

 strongly prominent, and the sides of the vertex are 

 sharply striated, the central part, as well as the occiput 

 and neck, heing nearly smooth or very finely alutaceous, 

 like the convex disk of the thorax on each side. The elytra 

 are rather strongly punctulated throughout, towards the 

 base granulate-punctate, and the large bluish rounded 

 shallow umbilicated foveoles are scattered from the base 

 nearly to the apex; the apices are separately rounded, 

 the edges not serrulated, the sutural apex spinose. The 

 sides of the body are thinly and loosely pubescent, the 

 trochanters blacldsh, the legs purple-coppery, cyaneous 

 towards the base of the femora. 



This species comes nearer King's description of his 

 C. semicircularis than any other Mexican form that I 

 have seen. It agrees in form, which Klug says is that 

 of C. flexuosa, but it differs in the colour of the head, 

 in the labrum being distinctly unidentate in the ? , in 

 the impunctate thorax, and in the absence of a second 

 submarginal spot on the elytra ; and it may therefore be 

 a nearly allied and distinct species. At any rate, the 

 species referred to C. semicircularis in the ' Biologia 

 C.-A.,' on the authority of French collections, cannot be 

 that of Klug, who describes the labrum as scarcely 

 armed and the thorax as finely punctured, the wrongly- 

 named insect having the labrum greatly produced, almost 

 narrowly sublobate in the middle in both sexes and 

 strongly tridentate, and the thorax rather coarsely and 

 densely sculptured. It will require, therefore, a new 

 name : —
