Habitat in graminosis MadersEj semel tantum (Maio exeunte a.d. 184.9) lecta. 



C. short, rounded-ovate, rather less opake than the last species, and of a pale j'ellowish-green. Body 

 beneath, with the head and breast black. Prothorax and ebjtra with the sides much expanded, 

 though more obliquely so than in the C. nebulosa, and scarcely at all recurved ; the former closely, 

 but almost obsoletely punctured, with its posterior angles acute, and free from all inequalities 

 (there being scarcely any appearance of even a dorsal line). Elytra very convex, and with their 

 humeral angles rather less poiTCcted, and much more acute, than in the last species ; concolorous 

 with the rest of the surface ; and rather finely and very closely punctured, but with scarcely any 

 tendency to lines or stria;. Antennce, legs and abdomen more distinctly yellow than the rest of the 

 surface. 



Likewise an exceedingly rare insect in Madeira, the only individual which I 

 have seen having been captured by brusliing the long grass on the steep bank to 

 the left of the great Waterfall at the head of the Ribeiro de Santa Luzia, — during 

 my encampment there, with the llev. H. T. Lowe, at the end of May 1819. Like 

 the C nebulosa, it is found throughout the greater portion of Europe, though 

 more especially towards the south. It is recorded by M. Lucas in Algeria ; and 

 I possess a specimen from the Canary Islands, taken by the Rev. W. J. Armitage 

 in Teneriffe. Its smaller size and rounded form, in conjunction with its simply 

 and closely punctulatcd surface, and its uniformly pale yellowish-green hue, will, 

 apart from minor differences, at once distinguish it from the last species.
