This beautiful Bembidium (the most elegant of aU the Canarian 

 Coleoptera) is apparently extremely rare, though widely spread over 

 the archipelago. I have taken it by the edges of the little stream 

 at Haria, in the north of Lanzarote ; in a similar position at La An- 

 tigua, in Fuerteventiu'a ; and close to Ycod de los Vinhos, of Tene- 

 riffe ; in which last island it was likewise captured by Mr. Gray (in 

 the Barranco Santo, near S'''Cruz), and more abundantly by Dr. Crotch 

 (above Ycod el Alto). It was also found byM. Hartung in Fuerte- 

 ventura. And I am informed by Dr. Schaum that it was taken by 

 Kiesenwetter at Naupha, in Greece ; but I have not had the oppor- 

 tunity of comparing a Grecian type with the Canarian ones.

112. Bembidium Crotchii, n. sp. 



B. capite prothoraceque submetaUice fusco-piceis, subopacis, illo parce* 

 punctato, hoe cordato fere impunctato sed ad basin transversim 

 constricto subrugoso ; elytris nitidioribiis, testaceis, circa scuteUum 

 triangulariter submaculatis necnon in disco postico obsoletissime 

 (vix perspicue) dentato-subfasciatis, punctato-striatis, striis postice 

 evanescentibus ; antennis (brcviusculis), palpis pedibusque rufo- 

 testaceis. — Long. corp. lin. 2-2^. 



Habitat Palmam, rarissime, mihi non obvium; a Dom. W. D. Crotch, 

 Medic. Doct., in humidis supra Sanctam Crucem nuper repertum. 

 Species valde distincta formosa indigena, necnon in honorem capta- 

 toris indefessi oculatissimi a meipso citata. 



This most interesting Bembidium, the discovery of which (in the 

 island of Palma) is due to the indefatigable researches of Dr. Crotch, 

 is clearly the representative at the Canaries of the European B.palli- 

 dipenne, — though at the same time most abundantly distinct from it 

 specifically. It may at once be known from it by its almost ojnxl-e, 

 hrownisli-piceous head and prothorax (which are but faintly metallic, 

 and both of which, though particularly the latter, are less evidently 

 punctured), and by its (pale rufo-testaceous) elytra having their 

 scutellary blotch and dentate postmedial fascia nearly obsolete. The
