Taken hitherto only in Grand Canary, where it occurs both in 

 sylvan and subsylvan spots of intermediate and lofty elevations. 



96. Calathus spretus. 



Calathus spretus, Woll., Ann. Nat. Hist. ix. 352 (1862). 

 1 Id., Cat. Can. Col. 39 (1864). 



Habitat Canarienses (Hierro), prgecipue in intermediis vulgaris. 



A Canarian Calathus which is common throughout the intermediate 

 elevations of Hierro, to which island it would seem to be peculiar. 

 It bears a considerable primd fade resemblance to the C. barbatus 

 from Grand Canary ; and it is the only exponent of the genus which 

 has been detected in Hierro. 



Genus 28. ANCHOMENUS.

97. Anchomenus Nichollsii. 



' Anchomenus Nichollsii, Woll, Cat. Can. Col. 40 (1864). 



Habitat Canarienses (Ten., Gom.), inter lapillos et sub lapidibus per 

 margines rivulorum in editioribus vulgaris. 



A Canarian Anchomenus which was discovered by Dr. Crotch and 

 S. T. Nicholls, Esq., in the spring of 1862 ; and which has since 

 been captured in profusion, not only by the former but also by his 

 brother, Mr. G. E. Crotch, during their late expedition to those 

 islands. Erom the report before me, it seems to abound in the higher 

 districts of Gomera occurring " by the edges of every stream " ; but 

 it is clearly much more scarce in Teneriffe (where I myself indeed 

 have never met with it), though it was certainly found there by Dr. 

 Crotch above Ycod el Alto during his first Canarian campaign. 



98. Anchomenus debilis. 



Anchomenus debilis, Woll, Cat. Can. Col. 41 (1864). 



Habitat Canarienses (Can.), inter lapillos ad margines rivulorum 

 rarissimus. 



The only specimens which I have seen of this insect I captured at 

 the edges of a stream at Teror, in Grand Canary. Having now had 

 an opportunity of comparing it with a more extensive series of the 

 A. Nichollsii, I am quite satisfied that the two species (although 

 closely allied to each other) are totally distinct.
