74 CANARIAN C'OLEOl'TERA. 



only three examples which I have seen, Dr. Crotch informs me that 

 he captured in a wet and nearly inaccessible spot at the edges of a 

 Levada on the mountain-slopes above S''^ Cruz, of Palma, during the 

 spring of 1862.

Whether the two examples from wliich the above diagnosis has 

 been compiled are indicative of more than a geographical phasis of 

 the common European B. varium I will not undertake, in the absence 

 of further material, to pronounce for certain. They would seem in 

 some respects indeed to be intermediate between that species and the 

 Jlammulatum — being nearer perhaps to the latter in their paler hue, 

 but to the former in their general sculpture and somewhat smaller 

 size. Their head and pro thorax however are rather more brightly 

 metallic than is usually the case ■with the B. varium ; and the latter 

 is more strongly margined at the edges and has its extreme posterior 

 angles a trifle more acutely prominent. They were both of them 

 captured Ln Teneriff'e (I believe above Ycod el Alto), during the 

 spring of 1862, by Dr. Crotch, — to whose careful researches we are 

 indebted for several recent additions to the Canarian fauna.
