Habitat Maderenses (Mad.) et Canarienses (Fuert., Can., Ten., Gom., 

 Palmd), in humidis vulgaris. 



The European S. Teutonus (which I possess also from the Azores, 

 and which I met with at Mogadore on the opposite coast of Africa) 

 is probably nearly universal throughout these Atlantic islands. At 

 the Madeiran Group, however, it has been observed hitherto only in 

 Madeira proper, where it is common in damp places at most eleva- 

 tions. But at the Canaries it has been captured in all the seven 

 islands except Fuerteventura and Hierro (in both of which, however, 

 we may be pretty sure that it exists)*. It is a species of a very 

 wide geographical range.

Habitat Salvages (ins. majorem, borealem), a Barone de Paiva semel 

 communicatus. 



Tne only Atlantic example which I have yet seen of this Euro- 

 pean Stenoloplius has been communicated by the Barao do Castello 

 de Paiva, by whom it was obtained from the Great Salvage ; and 

 although I have no reason to question the correctness of its stated 

 habitat, yet I cannot but feel that further material would be desi- 

 rable in order to establish it beyond the possibility of a doubt t. 

 It appears to be found, chiefly, in Mediterranean latitudes. 



* The principle of priority in nomenclature (which seems to be, in a general 

 sense, the only just one) has occasioned some little confusion regarding the 

 synonymy of this species. It appears to have been first described by Fabricius 

 (in 1775) as the Carabus vaporariorum (as he supposed) of Linnaeus. But inas- 

 much as Linnaeus's insect was in reality totally distinct, and two beetles cannot 

 at any time be allowed to bear the same name in the same genus (even though 

 they be subsequently placed in different genera), it follows that the later of them 

 (which in this case is Fabricius's) must be suppressed, and that the next published 

 title (in this instance by Schrank) should be accepted in lieu of it. 



t The S. discophorus would seem to differ from the Teutonus in its paler hue, 

 in the dark portion of its elytra (which have their short second stria rather less 

 abbreviated) being so far reduced in size as to form a comparatively small patch 

 on the hinder disk, and in its prothorax being more narrowed posteriorly, and 

 therefore less evenly rounded at the sides.
