CANARIAN COLEOPTERA. 85 



metallic elytra! striae (the subsiitural ones of which are scarcely per- 

 ceptibly impressed), and the ferruginous hue of its body beneath, 

 will readily distinguish it. I have taken it in Grand Canary ; near 

 S"' Cruz and Orotava, in Teneriffe; and, dui-ing February 1858, it 

 was captured by Mr. Gray and myself in the valley above San Se- 

 bastian, of Gomera, — from which locality it was subsequently ob- 

 tained by Dr. Crotch. I have also received it from Professor Heer 

 (collected byM. Hartung in Teneriffe) under the name of ''G. na- 

 tator,^'' from which however it is totally distinct.

Habitat in Canaria et Teneriffa, hinc inde vulgaris. 



The rather smaller size and narrower outline of the present Oy- 

 rinus, combined with its more deeply punctured striae (which are 

 concolorous with the rest of the surface), its more straightly trun- 

 cated elytra, and the darker hue of its body beneath, will, apart from 

 minor differences, at once separate it from the last species. It 

 closely resembles the common O. natator, but is a trifle more oblong, 

 with its striae more coarsely punctured, with its elytra more straightly 

 truncated at their apex, and with its reflexed margin dark -aeneous 

 (instead of ferruginous). It is common throughout central and 

 southern Europe, and appears to be likewise common in these islands. 

 I have taken it abundantly at Arguiniguin, in the south of Grand 

 Canary ; as also near S'^ Cruz, Souzal, and Orotava, in Teneriffe.

The common European P. prolifericomis, which is universal at 

 Madeira and which is recorded by M. Morelet at the Azores, occurs 

 rather abundantly in wet spots at the Canaries. Hitherto, however,
