CANARIAN COLEOPTERA. 69 



type (from Greece) which he has sent me, I can perceive a very evi- 

 dent rufeseent tinge in that region of the elytra ; and I have there- 

 fore no hesitation in regarding the Canarian species as identical with 

 the European one. I have taken it in Grand Canary, and also im- 

 mediately outside the Puerto Orotava of Teneriife, — in the latter of 

 which islands, as well as in Gomera, it was captured by Dr. Crotch.

Habitat in Canaria Grandi, prope oppidum Teror semel lectum. 



The only specimen of this common European insect which I have 

 as yet seen from any of the Atlantic islands was taken by myseK in 

 Grand Canary (at the edge of a small stream close to the town of 

 Teror), during April 1858. I can detect nothing to separate it from 

 the ordinary northern type, except that its prothorax is a little less 

 strongly margined at the sides, — a difference which can scarcely be 

 regarded (even if permanent) as indicative of more than a sKght 

 geographical modification. 



106. Bembidium vicinum.

I refer this insect to the B. vicinum (from the south of Europe 

 and the north of Africa) on the authority of Dr. Schaum, who has 

 also kindly sent me an Italian type for comparison. The Canarian 

 specimens are altogether a little larger, broader, and more depressed 

 than the example which he has communicated, and have their limbs 

 perhaps somewhat longer and paler ; but they do not differ sufficiently 

 to warrant the supposition that they are specifically distinct. In 

 habits and general aspect it is closely related to the European B. 

 ceneurti, but has its prothorax rather less rounded at the sides (the 

 posterior angles being a little more prominent and defined), its sur- 

 face a trifle more alutaccous and less shining, its striec lighter, and
