CURCULIONID/G. 331 



A Canarian Liclienophagus which has been observed hitherto only 

 in Teneriffe, where it is common beneath stones in certain spots of 

 a rather low altitude particularly around the Villa and Puerto of 

 Orotava. 



919. Lichenophagus persimilis. 



Lichenophagus persimilis, Woll., Cat. Can. Col. 365 (1864). 



Habitat Canarienses (Ten., Palma), sub lapidibus in intcrmediis 

 occurrens. 



Also Teneriffan, and very closely allied to the last species ; but 

 found at a higher elevation (my examples having been taken at 

 Ycod el Alto), and differing in a few jmall but constant particulars 

 which have been fully alluded to in the published diagnosis. I also 

 met with it sparingly in the island of Palma, in the Barranco above 

 S** Cruz ; but the Palman individuals, which represent the " var. 

 f3. seriesetosa " of my description, differ from the Teneriffan ones in 

 having their longitudinal rows of short setae somewhat longer and 

 paler (and therefore more apparent). 



920. Lichenophagus subnodosus. 



Lichenophagus subnodosus, Wott., Cat. Can. Col. 366 (1864). 



Habitat Canarienses (Ten., Hierro), in intermediis praesertim sylva- 

 ticis degens. 



Not uncommon at intermediate and rather lofty altitudes in 

 Teneriffe and Hierro, of the Canarian Group, particularly within 

 the sylvan and subsylvan districts. The examples from Hierro, 

 taken by myself and the Messrs. Crotch, and representing the " var. 

 /3. subcalva " of my diagnosis, differ from the Teneriffan ones in 

 having the setae of their elytra considerably shorter; but I can 

 detect nothing about them to warrant the suspicion that they are 

 specifically distinct. 



921. Lichenophagus sculptipennis. 



Lichenophagus sculptipennis, Woll, Cat. Can. Col. 367 (1864). 

 Habitat Canarienses (Palma, Hierro), in intermediis minus frequens. 



Found in Palma and Hierro, of the Canarian Group, and in 

 some respects intermediate (as will be gathered by a reference to its 

 diagnosis) between the L. subnodosus and impressicollis. Further 

 material must decide whether it can be regarded as an extreme state
