CURCULIONID^. 



of either of them ; meanwhile I believe that its recorded distinctions 

 (particularly those of sculpture) are quite sufficient to necessitate its 

 isolation. At the same time I should add that three examples now 

 before me, which were taken by the Messrs. Crotch in Hierro, seem 

 to have their elytral punctures (although very large) less enormous 

 than is the case in the Palman type. 



922. Lichenophagus impressicollis. 



Lichenophagus impressicollis, WolL, Cat. Can. Col. 368 (1864). 



Habitat Canarienses (Ten.}, in lauretis humidis editioribus hinc 

 inde parum vulgaris. 



A fine Canarian species which I have observed hitherto only in 

 the laurel-woods of Teneriffe, where it occurs in damp and shady 

 spots of a rather high elevation. Indeed all my specimens were 

 obtained on the north-eastern mountains of that island at Las 

 Mercedes, above Taganana, and towards Point Anaga. 



923, Lichenophagus bnccatrix. 

 Lichenophagus buccatrix, Woll., Append, huj. op. 54. 



Habitat Canarienses (Gom.), in locis valde elevatis a DD. Crotch 

 parce lectus. 



A large and most singular Canarian Lichenophagus which was 

 taken sparingly by the Messrs. Crotch at a high elevation in Gomera, 

 by beating plants of Sedum on Monte Fuerte one of the loftiest 

 mountains above Hermigua*. 



(Subfam. XXV. TANYMECIDES.) 



Genus 276. THYLACITES. 

 Germar, Ins. Spec. i. 410 (1824). 



* Somewhat in this position, and probably under the subfamily Cyphides, I 

 may allude to a reputed Teneriffan weevil, the Curculio cribrarius of Olivier 

 a rather large species, which Dejean (and, after him, Schonherr, who appears, 

 however, never to have examined it) placed in the genus Geonemus. Neverthe- 

 less to the latter it clearly does not belong ; and M. Jekel has suggested that it 

 has probably much more in common with the South-African group Catamonus. 

 But be this as it may, I feel almost certain that Olivier was mistaken as to 

 its habitat, and that the insect, so far from being Teneriffan, is not even a 

 Canarian one. For further remarks on this question, as well as for a diagnosis 

 of the Curculionid referred to (the original type having been lent me by M. 

 Chevrolat), vide p. 369 of my Canarian Catalogue.
