CANARIAN COLEOPTEKA. ' 33 



it belongs to. It is remarkable for its basaUy •wide (though altogether 

 not very broad) prothorax, for its subopake ovate elytra (which are 

 a good deal expanded behind the middle, and have, apparently, but 

 two punctures developed on their disk), for its fusco-piceous hue, 

 and for its rather elongate, slender limbs. There is certainly no 

 species here enumerated to which it could be referred. 



54. Calathus abacoides. 



Calathus abaxoides ?, BruUe, in Webb et Berth. (Col.) 56 (1838).

Habitat in sylvaticis humidis Teneriffae, sat frequens. 



I refer this insect to M. BruUe's C. ahaxoides from the mere fact 

 of the latter's specific 7iame, there being no other Canarian Calathns 

 which could be compared in outline to an Abax ; but since he 

 says that the abaxoides is much of the same form as his following 

 species, the C. annularis (which is an Argutor, and no Calathns at 

 all), and since he speaks of it as " cinq lignes de longueur," whilst it 

 is only four, I cannot but feel doubtful, in the absence of even a 

 single distinctive character in his diagnosis, whether it be correctly 

 identified. It may readily be known by its small size, elliptical out- 

 line, and the almost equally shining surface of its prothorax and 

 elytra ; the former of which is broad posteriorly and almost unre- 

 curved at the sides (except slightly so towards the basal angles) ; 

 whilst the latter are gradually somewhat narrowed behind, Avith 

 their interstices slightly convex, and with their discal punctures 

 (from three to five on the third interstice) pretty e\ident. 



The C. abacoides is rather abundant throughout the sylvan regions 

 of TenerifFe, occurring in exactly the same places as the last species. 

 I have observed it more particularly at the Agua Garcia, above 

 Taganana, and at Las Mercedes. It has also been communicated 

 by the Barao do Castello de Paiva and Professor Heer of Zurich, the 

 latter of whom obtained it from M. Hartung. 



55. Calathus ascendeus. 



Calathus ascendens, Woll., loc. cit. 345 (1862). 

 Habitat sub lapidibus in montibus Teneriffae, usque ad 8000' s. m. 

 ascendens. 



The present Calathus (which I have observed only in Teneriffe) 

 is essentially an inhabitant of the loftiest elevations, attaining its 

 maximum at about 8000 feet above the sea, and but rarely descending 

 into the sylvan districts. It may be known by its only slightly
