12 CARABID^E. 



has been detected only in Madeira proper, where it is essentially 

 mountain species, occurring, sometimes abundantly, from about 

 2000 feet above the sea to the summits of the peaks. 



28. Tarus marginellus. 



Cymindis marginella, Brulle, in Webb et Berth. (Col.) 55 (1838). 

 Tarus marginellus, Woll, Cat. Can. Col. 20 (1864). 



Habitat Canarienses (Lanz.), sub lapidibus in aridis parce occurrens. 



Hitherto this Tarus has been observed only in the north of Lan- 

 zarote, of the Canarian Group where it occurs sparingly, beneath 

 stones, on the barren rocky ground immediately behind the Salinas, 

 towards the Eisco. 



29. Tarns cinctus. 



Cymindis cincta, Bridle, in Webb et Berth. (Col.) 55 (1838). 

 Tarus cinctus, Woll., Cat. Can. Col. 20 (1864). 



Habitat Canarienses (Can., Ten. 1 ?), in montibus excelsis degens. 



A few specimens of this remarkable Tarus, taken by myself at a 

 high elevation on the mountains of Grand Canary (in a lofty Pinal 

 of the district of Tarajana), are all with the exception of M. Brulle's 

 type, and an example which has just been communicated by M. de 

 Marseul that I have yet seen. It must therefore be considered 

 both local and rare. De Marseul 's specimen, which was captured by 

 M. de la Perraudiere, is labelled as coming from " Teneriffe." It is 

 very possible that this habitat may be correct; nevertheless since 

 many of the insects in the same consignment have (without doubt) 

 wrong localities indicated for them, I think it safer to query Tene- 

 riffe for the species. The prothorax of this particular example is 

 just perceptibly wider, and its punctation is (if anything) not quite 

 so deep as in the Grand-Canarian ones ; so that it is far from unlikely 

 that it may represent some slight insular (Teneriffan) modification 

 of the species. 



30. Tarus velatus. 



Tarus velatus, Woll., App. huj. op. 2. 

 Habitat Canarienses (Gom.), in lauretis humidis editioribus degens 



Ujra 



ins. 



A Canarian Tarus, apparently peculiar to the sylvan regions of 

 Gomera where it was detected by the Messrs. Crotch, during the 

 summer of 1864, at a high elevation on the laurel-clad mountains 

 above Hermigua.
