254 CANARIAN COLEOPTERA. 



but we may be almost certain that it will be found generally, where- 

 ever the remains of the old laurel-forests, which are fast disappearing, 

 still exist. TenerifFan examples have also been communicated by 

 Dr. Crotch.

, Woll, Ins. Mad. 283 (1854). 



, Id., Cat. Mad. Col. 94 (1857). 



Habitat in sylvaticis Teneriffae et Palmse, minus frequens. 



Like the Cis hmri, the present insect abounds in Madeira, but is 

 comparatively scarce, and also exceedingly local, at the Canaries. 

 Hitherto I have observed it only in sylvan and subsylvan spots of the 

 intermediate altitudes of TenerifFe and Palma, — namely at the Agua 

 Garcia and the laurel-woods above Taganana of the former, and 

 high up in the Barranco da Agua of the latter.

411. Tomicus nobilis. 



T. cylindricus, piceo-niger, subnitidus, pilis tenuibus longissimis 

 erectis fulvescentibus praisertim in limbo obsitus ; prothorace elon-

Tomicus nobilis, Woll., Ann. Nat. Hist. (3rd series) ix. 441 (1862). 



Habitat in pinetis TenerifFa? et Palmae, lignum antiquum destruens. 



This large Tomicus is remarkable for the hinder portion of its pro- 

 thorax being coarsely punctured (with the punctures distinct and 

 well defined) ; for its elytra being more or less piceous and the head 

 and prothorax piceous-black, whilst its legs are more rufeseent, with 

 their tarsi (like the antennae) testaceous ; and for its elytra being
