Habitat Canarienses (Can., Gom.), in loeis similibus ac prsecedens. 



Likewise a Canarian species, and one which has been observed 

 hitherto only in the sylvan districts of Grand Canary and Gomera. 

 In the former it was taken by myself, on the wooded mountains near 

 Osorio ; and in the latter by the Messrs. Crotch, in the laurel-forests 

 above Hermigua. As will be seen from the amended diagnosis of it 

 which I have given in the Appendix, it presents in Gomera two 

 slightly different forms, both of which have much in common with 

 the T. velatus. 



32. Tarns zargoides. 



Tarus zargoides, Wall, Ann. Nat. Hist. xi. 214 (1863). 

 , Id., Cat. Can. Col. 21 (1864). 



Habitat Canarienses (Ten.), in sylvaticis editioribus humidis prseser- 

 tim lauretis parce occurrens. 



This interesting little Tarus, which may perhaps be regarded as 

 the Canarian representative of the T. cordatus of southern Europe, 

 has been detected hitherto only in the sylvan regions of Teneriffe 

 where moreover it is decidedly scarce, occurring sparingly at in- 

 termediate and lofty altitudes. 



Genus 15. DROMIUS.

Habitat Canarienses (Fuert.), rarissimus ; semel tantum captus. 



The sole authority for the admission of this European Dromius 

 into the Atlantic fauna is a single immature specimen which I cap- 

 tured in the Rio Palmas of Fuerteventura. And although I am 

 nearly certain that it is referable to the agilis of more northern 

 latitudes, and quite satisfied that it cannot be conspecific with any 

 of the other forms here enumerated, I nevertheless cannot but feel 

 that further evidence is greatly wanted before its identification can 

 be regarded as absolutely settled.
