1199. Ditylus concolor. 



Ditylus concolor, Brulle, in Webb et Berth. (Col.) 70, pi. i. f. 13 (1838). 



fulvus, Wott., Ins. Mad. 523 (note) (1854). 



concolor, Id., Cat. Can. Col. 512 (1864). 



Habitat Salvages (ins. majorem, borealem, et minorem, australem) et 

 Canarienses (Can., Ten., Gom., Palma, Hierro}, plerumque juxta 

 radices plantarum praesertim Euphorbiarum latens. 



This beautiful Ditylus seems to be widely spread over the Canarian 

 archipelago, where very likely it will be found to be universal. It 

 occurs beneath stones and amongst small broken sticks around the 

 roots of plants, particularly the Euphorbias ; and although I have 

 not observed it in its previous states, I think it far from improbable 

 that it is of Euphorbia -infesting habits. It has been captured in 

 Grand Canary, Teneriffe, Gomera, Palma, and Hierro; and it is 

 found likewise on the rocks of the Salvages a single example 

 having been taken on the southern island (or Great Piton) by Mr. 

 Leacock of Madeira, whilst a second has recently been communicated 

 by the Barao do Castello de Paiva from the northern one (or Great 

 Salvage). Its detection in Hierro is due to the late researches of the 

 Messrs. Crotch. It is so closely allied to a species from the Cape de 

 Verdes, which I described under the trivial name ofpallidus, that I 

 cannot feel quite satisfied that the latter is more in reality than a 

 geographical (though well-marked) modification of it.

Habitat Canarienses (sec. DD. "Webb et Berthelot), mihi non obvia. 



This European insect is included by M. Brulle (under the name of 

 " Ditylus rufus, Fisch.") in his short list of Canarian Coleoptera, on 

 the evidence of examples supposed to have been found by MM. Webb 

 and Berthelot. I inspected the latter when in Paris, and they ap- 

 peared to me to be most unquestionably identical with the /. mela- 

 nura of more northern latitudes ; so that I have no option but to 

 admit tho species into the present Catalogue. I need hardly state
