552 CANARIAN COLEOPTERA. 



Habitat insiilas omnes Canarienscs, in stercore bo\dno et equino 

 vulgaris. 



The more parallel outline and blacker, less pubescent, and more 

 shining surface of this common European AleocJiara, in conjimction 

 with its darker limbs and more testaceous elytral dash, will readily 

 separate it from the puhenda. It is also more variable in stature — 

 ascending to a somewhat larger, and descending to a very much smaller 

 size. It occurs in the dung of cattle (independently of elevation), 

 and is universal throughout the archipelago — in the whole seven 

 islands of which I have myself captured it. In Lanzarote, Gomera, 

 and Palma it was found likewise by Mr. Gray, and in Teneriffe and 

 Gomera by Dr. Crotch. It abounds at the Madeiras. I have little 

 doubt that the species referred to by M. Brulle under the name of 

 •' A. fuscipcs, Grav." was entered in his most inaccurate list on the 

 strength of a large example of this Aleocliara ; for I have no evidence 

 of the fnscipes being found in ani/ of these Atlantic Islands, whereas 

 so universal and abundant an insect as the A. a-assiKscula could 

 scarcely have escaped the observation of even MM. Webb and Ber- 

 thelot. If such, however, be the case (which, I think, is pretty 

 evident), it is surj)rising how two species which differ so essentially 

 from each other could possibly have been confounded by M. Brulle.

In its general contour and sculpture, as well as in the coarse gri- 

 seous pubescence with which its subopake surface is clothed, this 

 Aleochara is intimately related to the European A. grisea, of which 

 indeed it is barely possible that it may be but a geographical state. 

 It diffei's in having its head just perceptibly narrower (or more 

 oval), in its elytra being more suffused with a reddish tint, and in 

 its limbs being paler or more testaceous, — the antennte being, also, 

 a trifle longer, with their apical joint obtuser, or less pointed. It 

 was taken sparingly by Mr. Gray and myself, from beneath a dead
