30 CARABID^E. 



81. Calathus cognatus. 



Calathus cognatus, Woll, Cat. Can. Col. 34 (1864). 

 Habitat Canarienses (Gom.), in lauretis editioribus vulgatissimus. 



The present Calathus is strictly a Gomeran one, having been taken 

 in profusion by the Messrs. Crotch during their lateCanarian researches. 

 From the report which they give, it would seem to abound every- 

 where within the laurel-districts of that island, at a high elevation*. 



82. Calathus rectus. 



Calathus fulvipes?, JBrutte[necLat.'], in Webb et Berth. (Col.) 5G (1838). 



rectus, WolL, Ann. Nat. Hist. ix. 346 (1862). 



, Id., Cat. Can. Col 34 (1864). 



Habitat Canarienses (Ten.}, in inferioribus intermediisque, passim. 



Peculiar apparently to Teneriffe, where it is found sparingly at low 

 and intermediate altitudes. 



83. Calathus simplicicollis. 



Calathus simplicicollis, Woll, Ann. Nat. Hist. ix. 347 (1862). 

 , Id., Cat. Can. Col. 35 (1864). 



Habitat Canarienses (Lanz.), in inferioribus aridis saxosis rarior. 



Detected hitherto only in the north of Lanzarote, of the Canarian 

 Group where it occurs sparingly at a low elevation on the rocky 

 ground between the Salinas and the Eisco. In size and general 

 contour it a good deal resembles the common European C. melano- 

 cephalus ; nevertheless I do not believe that its affinities are in reality 

 with that species. 



84. Calathus ascendens. 



Calathus ascendens, WolL, Ann. Nat. Hist. ix. 345 (1862). 

 , Id., Cat. Can. Col. 33 (1864). 



Habitat Canarienses (Ten.}, in montibus valde excelsis vulgatissimus ; 

 usque ad 8000' vel etiam 9000' s. m. ascendit. 



Strictly an alpine Calathus, occurring in profusion throughout 

 almost the loftiest districts of TenerifFe where it ascends to 8000 

 or even 9000 feet above the sea, and but seldom descends into the 

 sylvan regions. 



* The range in size of the C. cognatus is more than I indicated in my Canarian 

 Catalogue, where the diagnosis was compiled from only two examples which were 

 taken by Dr. Crotch in 1862. Instead, therefore, of "Long. corp. lin. 5," read 

 Long. corp. lin. 4^-6.
