Habitat Lanzarotam borealem, d. 9. Mart. a.d. 1859 duo speciraina 

 collegi. 



The present Dromius is nearly allied to the European D. nigriven- 

 tr'is, Thorn, (fasciatus, Dej.), from which indeed Dr. Schaum, to whom 

 I forwarded a single specimen for examination, professed himself 

 scarcely able (except in colour) to detect a satisfactory difference. 

 But, after a most careful comparison of two examples which I cap- 

 tured in the island of Lanzarote with an English series of the D. 

 nigriventris, I am quite satisfied that they cannot be specifically iden- 

 tical with the latter. Thus, they are not only altogether a little 

 larger, wider, and more robust than the nigriventris, but the head 

 and prothorax are verg perceptihhj larger (the latter, also, being more 

 convex), the legs are thicker, and the colour of the elytra is almost 

 uniformly of a dark piceous-brown, — there being only the faintest 

 possible trace of a more diluted portion towards the base and at the 

 extreme hinder margin. My two examples were taken amongst dry 

 earth and rubbish on some rocks at Ye, in the north of Lanzarote, 

 whilst encamped there, with the Rev. R. T. Lowe, on the 9th of 

 March 1859.

In general coloimng this beautiful little Dromius is very similar 

 to the D. Sigma ; nevertheless its comparatively minute size and ex- 

 ceedingly short prothorax, in conjunction with its more oblong and 

 distinctly striated elytra, with their relatively larger, darker, and less 

 dentate fascia, will at once separate it from that insect. It is appa- 

 rently one of the rarest of the Canarian Coleoptera, — foxir out of the 

 only five specimens which I have myself taken having been captured 

 at the base of perpendicular rocks high up in the Barranco da Agua 

 of Palma, and the remaining one in the dry cindery region imme- 

 diately above the Puerto Orotava of Teneiiffe. A single example 

 was obtained also in Gomera, by Dr. Crotch.
