Likewise Teneriffan, but more abundant and much more widely 

 diffused than the last species. It occurs beneath stones and dry 

 fallen leaves at low and intermediate elevations, ascending from the 

 sea-level to an altitude of about 3000 feet. 



600. Casopus alticola. 



Casapus alticola, WolL, loc. cit. 198, pi. viii. f. 2 (1862).

Habitat Canarienses (Ten.), in locis elevatis rarissimus. Usque ad 

 8000' s. m. ascendit. 



Attached to the loftier altitudes of Teneriffe, where it would 

 appear to be extremely rare. I have taken it above the Agua 

 Mansa, and on the elevated Cumbre adjoining the Caiiadas ; and it 

 has been found sparingly by the Messrs. Crotch in the Final above 

 Ycod el Alto. It is very closely allied to the C. dilaticollis, of 

 which indeed it may possibly be but a phasis peculiar to the higher 

 regions ; in which case the upward range of that species would, of 

 course, be greatly increased. Nevertheless, as stated in my paper 

 on the Canarian Ptinidce, I am more inclined to believe that 

 (however nearly resembling it) it is truly distinct from the dila- 

 ticollis*. 



601. Casopus pedatus. 



Casopus dilaticollis, var. y, Woll., Cat. Can. Col. 238 (1864). 

 pedatus, Id., Append, huj. op. 32. 



Habitat Canarienses (Gom.), a DD. Crotch repertus. 



The representative in Gomera of the Teneriffan C. dilaticollis (or 

 perhaps, rather, of the alticola), from which however it appears to 

 be sufficiently distinct as will be seen by a reference to my diag- 

 nosis, given in the Appendix to this volume. It was first found by 

 Dr. Crotch, during his sojourn in Gomera in the spring of 1862 ; in 



* The C. alticola is rather larger than the dilaticollis, with its pubescence not 

 quite so long ; its elytra are more deeply substriate-punctate, and have their 

 front transverse fascia developed (instead of being obsolete) ; and the first joint 

 of the hinder feet of the male is perhaps somewhat more inflated.
