270 CANARIAN COLEOPTERA. 



the remains of the old Finals still exist ; nevertheless hitherto I 

 have observed it only on the mountains above San Bartolome (in the 

 district of Tarajana) of Grand Canary, at the Agua Mansa in Tene- 

 rifFe, and in the Barranco above S"^ Cruz in Palma, — in the last of 

 which islands it was captured also by Dr. Crotch. Its cylindric out- 

 line, intensely black hue, and deeply sculptured surface give it much 

 the appearance at first sight of certain members of the Hylcsinidce ; 

 nevertheless, apart from all minor distinctions, the struetiire of its 

 undilated, apically uncinate, and externally simple tibise will imme- 

 diately remove it from the whole of those groups. 



Genus 182. EHYNCOLUS. 

 (Creutzer) Germ., Ins. Spec. 307 (1824). 



435, Ehyncolus crassirostris. 



Rhyncolus crassirostris, WoU., Trans. Ent. Soc. Lond. v. 367. pi. 18. 

 f. 3 (18G1). 



Habitat in montibus Canarise Grandis, pinos cmortuas destruens. 



The few examples which have come hitherto beneath my notice of 

 this insect I captured, during April 1859, from out of the trunk of 

 an old Finns canariensis, on the ascent to the Pinal above San Bar- 

 tolome, in the mountains of Grand Canary. It would appear, there- 

 fore, to have the same habits as the Eremotes crassicornis, and may 

 consequentl}^ be expected to occur in spots where the latter, and other 

 pine-infesting species, are found. Its distinctions from the European 

 i?. truncorum, which at first sight it somewhat resembles, may be 

 gathered from a reference to my Paper cited above. 



Genus 183. PHLCEOPHAGUS. 



Schonherr, Gen. et Spec. Cure. iv. 1047 (1838). 



436. Phloeophagus caulium. 



Phloeopbagus caidium, WoU., Trans. Ejit. Soc. Lond. v. 370 (1861). 

 Habitat Lanzarotam et Fuerteventuram, in tnxncis ramisque Eu- 

 phorbiarum emortuis degens. 



So far as observed hitherto, the present Pldceophagus seems to be 

 peculiar to the dead Euj)ho7-bia-stems of Lanzarote and Fuerteventura, 

 where it is occasionally veiy abundant, and in the former of which it 

 was first captured by Mr. Gray and myself, at Haria, during January 

 1858. It may be known by its deei)ly sculptured surface (the punc- 

 tures of its pro thorax, particularly in the Lanzarotan specimens, being 

 exceedingly large) and by its obsolete scutellum. the latter being
