thorax being suddenly and greatly constricted behind, but with the 

 posterior angles themselves exceedingly prominent) would appear, so 

 far as I have observed hitherto, to be peculiar to the intermediate and 

 higher elevations of Grand Canary, — where, dui'ing March and April 

 of 1858, 1 took it sparingly beneath stones throughout the dry, cindery 

 district of El Monte ; as well as on the summit of the Bandama moun- 

 tain, and on the ascent to the Roca del 8oucilho, above San Mateo. 



8. Carabus faustus. 



G, cupreo-aeneus vel subaenescenti- (interdum virescenti-) niger, 

 nitidus ; prothorace elongato-subquadrato (postice paulo et aqua- 

 hter angustiore) ; elytris elongato-ovatis (versus basin ad latera 

 oblique subrectis et pone medium paulo latioribus), limbo plus 

 minus Isete virescenti, longitudinaliter triseriatim tuberculatis nec- 

 non plus minus distincte costatis ; antennis pedibusque elongatis, 

 robustis, obscurioribus. — Long. corp. lin. 12-13.

Habitat Teneriffam sylvaticam, rarissimus. 



I have not, myself, ever taken this Carabus ; but I have received 

 it from Dr. Heer of Zurich, captured by M. Hartung in Teneriffe, 

 and it has also been communicated by the Barao do Castello de Paiva 

 from (the Agua Garcia of) the same island. If therefore the few 

 specimens which I have seen be typical of the species, I may add 

 that it may be known from the C. interruptns by its considerably 

 larger size and more shining surface, by its longer and robuster limbs, 

 and by its prothorax and elytra being each of them more elongated, — 

 the former being more (obliquely) straightened behind, and the latter 

 more so in front. The posterior thoracic angles, also, are a little 

 more backwardly-produced. It is evidently extremely rare, and is 

 j)robably attached to a rather lower elevation within the sylvan dis- 

 tricts than its ally. 



9. Carabus interruptus. 



C. cupreo-teneus vel subajnescenti- (interdum virescenti-) niger, sub- 

 nitidus ; prothorace subquadrato (postice paulo et a^qualiter an- 

 gustiore) ; elytris ovatis, limbo plus minus Isete virescente, longi- 

 tudinaliter triseriatim tuberculatis necnon plus minus distincte 

 costatis ; antennis pedibusque obscurioribus. — Long. corp. lin. 8^- 

 vix 10. 



Carabus interruptus (Lat.), Dej., Spec. Gen. des Col. v. 547 (1831). 

 abbreviatus, Brulle, in Silb. Her. Ent. iii. 298 (1835).
