HISTERID^E. 



clusively attached. In Madeira proper it was detected by the late 

 Mr. Bewicke, in the district to the east of Funehal ; whilst at the 

 Canaries it is far more abundant, and has been captured in all the 

 islands except Palma. But as there can be little doubt that sooner 

 or later it will be met with in Palma likewise, we may feel nearly 

 certain that in the Canarian Group at any rate it is universal.

497. Teretrius cylindricus. 

 Teretrius cylindricus, Wott., Cat. Can. Col. 164 (1864). 



Habitat Canarienses (Ten., Gom.), in Euphorbia canariensi degens. 



A Canarian Teretrius which appears to be of Euphor bia -infesting 

 habits ; for although the only example which I myself met with was 

 captured accidentally on the inner canvas of my tent, whilst encamped 

 at the Agua Garcia in Teneriffe, it has nevertheless been taken sub- 

 sequently by the Messrs. Crotch in Gomera out of the decayed stalks 

 of the Euphorbia canariensis. 



Genus 155. HOLOLEPTA.

Habitat Canarienses (Ten., Gom.), sub cortice EupTiorbiarum laxo 

 emortuo rarissima. 



This noble Histerid appears to be peculiar to the dead Euphorbias 

 of the Canarian Group, where it is of the greatest rarity. Indeed 

 the only two examples which I have seen were captured by Dr. Crotch 

 in Gomera one during the spring of 1862, and the other in the 

 summer of 1864, the latter of them having been taken out of a 

 rotten Euphorbia. It was, however, described by De Marseul from 

 a specimen stated to have been brought by M. de la Perraudiere 

 from Teneriife ; and since his type seems to have been smaller than 

 the two individuals from Gomera, it is extremely probable that his 

 habitat is correct, and that the Teneriffan examples (wheresoever 

 found) may perhaps be somewhat smaller than the Gomeran ones.
