HISTERID^E. 167 



476. Eubrachium ovale. 



Eubrachium ovale, W6U., loc. cit. 161, pi. vii. f. 9 (1862). 

 , Id., Cat. Can. Col 182 (1864). 



Habitat Canarienses (Hierro), in locis similibus ac praecedens. 



Of precisely the same habits as the last species, and almost equally 

 rare. The only island in which it has been found is Hierro, the 

 most western one of the Canarian Group where it was taken by 

 myself in 1858, and by the Messrs. Crotch in 1864, beneath the 

 rotting bark of old Euphorbias. 



477. Eubrachium punctatum. 



Eubrachium punctatum, Wott., loc. cit. 162 (1862). 

 , Id., Cat. Can. Col. 181 (1864). 



Habitat Canarienses (Ten., Gom., Palma), in sylvaticis humidis edi- 

 tioribus sub cortice laurorum laxo latens. 



Whilst the two preceding species are of Euphorbia-infesting habits, 

 the present one appears to be attached to the laurels of intermediate 

 and lofty altitudes. I have taken it beneath the loosened bark of 

 old trees in the damp wooded regions of Teneriffe and Palma ; and 

 it has been captured by the Messrs. Crotch, in similar situations, in 

 Gomera. 



Genus 149. XENONYCHUS. 

 Wollaston, Cat. Can. Col. 179 (1864). 



478. Xenonychus fossor. 

 Xenonychus fossor, Woll, Cat. Can. Col. 181 (1864). 



Habitat Canarienses (Fiwrt., Can."), in arenosis aridis maritimis ad 

 radices plantar um parce fodiens. 



This remarkable Canarian Histerid resides in sandy places near 

 the coast, where it burrows into the dry hillocks of loose sand which 

 have gradually accumulated around the roots of the various shrubby 

 plants which stud those arid wastes. In such situations it was 

 taken by Mr. Gray and myself, to the south of Puerto de Cabras, in 

 Puerteventura ; and two examples are now before me which were 

 captured by the Messrs. Crotch during the summer of 1864, in the 

 sandy district of Grand Canary between Las Palmas and the Isleta. 

 Like so many of the sand-infesting Coleoptera, it is most anomalous 

 in structure ; but its various peculiarities have been fully alluded to 

 in my generic and specific diagnoses.
