elytra, and its testaceous limbs, will at once sej^arate it from the 

 other species here enumerated. Only nine examples have come 

 hitherto beneath my notice ; and it may be considered, therefore, as 

 decidedly rare. They were all taken in the wooded region above the 

 Agua Mansa of Teneriffe ; so that the species is probably peculiar to 

 the ui)per portion of the sylvan districts.

Calathus carinatus?, Brulle, in Webb et BeHh. (Col.) 55 (1838).

Habitat TenerifFam, in locis similibus ac prcecedens, sed pariim 

 vulgaris. 



A most remarkable species, at once known by its narrow, elongate- 

 quadrate prothorax and hy its extremely depressed, opake and el- 

 liptical elytra, which have the basal line of each (from either shoulder 

 to the scutellum) verj' deeply curved, and their discal punctures (of 

 which there are usually from five to nine on the third, from about 

 two to four on the fifth, and occasionally one or two on even the 

 seventh interstice) exceedingly distinct. I have but little doubt that 

 it is the C. carinatas of M. Brulle ; for although I was not able, 

 whilst in Paris, to obtain a sight of his CaJathi, yet I think there is 

 just sufiiicient in the description (so called) to render it probable that 

 this is the insect to which he referred, — though his total silence on 

 all the salient peculiarities of the four Canarian species which he 

 wished to indicate (one of which is no Calathus at all, but an Aryutor) 

 renders his diagnoses utterly worthless. 



The C. carinatus is rather common throughout the sylvan regions 

 of Teneriffe. I have taken it abundantly at the Agua Garcia, as 

 also in the woods above Taganana and at Las Mercedes ; in the last 

 of which localities it was also found by the Barao do Castello de 

 Paiva.

 Calathus advena, JFoll., he. eit. 344 (1802). 



Habitat Canariam Grandem, tempore vernali a.d. 1858 specimen

The present Calathus is the only one of which I had not an ex- 

 tensive series to compile my diagnosis from, the single specimen 

 which I have seen being one which I captured in Grand Canary (I 

 believe in the region of El Monte) during the spring of 1858. Fortu- 

 nately, however, it happens to be a male, so that I can have no hesi- 

 tation (from its simple unfimbi'iated tibia3) as to which of my Sections
