The distinctions between the present species and the last one 

 have already been pointed out, — the whiter and less dense pube- 

 scence of the B. albidus, in conjunction with its almost concolorous 

 pronotunij its still more powerfully developed prothoracic spine, 

 its less evident and more broken elytral lines, and its usually 

 more perceptible (and paler) elytral spots, being at once sufficient 

 to separate it from the B. annulicornis , Its long, suberect addi- 

 tional hairs, also, are for the most part even less numerous than 

 is the case in that insect. I have taken it, from beneath the loose 

 outer-fibre of dead Euphorbia-stems, in Lanzarote and Fuerte- 

 ventura ; as also at Taganana, and on the mountains above Santa 

 Cruz of Teneriffe. 



37. Blabinotus pilosus,* n. sp. 



B. angusto-subcylindricus (apice vix attenuatus), piceus, pilis 

 demissis subflavo-albidis densissime tectus et longioribus sub- 

 erectis sat dense obsitus ; prothorace ad latera spina medid 

 brevi anguliformi armato, postice magis quara antice con- 

 stricto ; elytris lineis fractis nigrescentibus obscuris longi- 

 tudinaliter ornatis ; antennis pedibusque annulato-variegatis. 



Long. corp. lin. 4 — 6. 



Habitat in Lanzarota, rarissimus : primus detexit Dom. Gray. 



The narrower outline of the B. pilosus (the elytra of which are 

 but slightly wider than the hinder region of the prothorax), in 

 conjunction with its much shorter, and almost anguliform, pro- 

 thoracic spine, and the comparatively broader anterior portion of 

 its prothorax (which is much less constricted than the hinder half), 

 and its denser suberect additional pile, will readily separate it from 

 both of the preceding species. It is apparently very rare, and was 

 first detected by John Gray, Esq., near Haria, in the north of 

 Lanzarote, during our sojourn there in January, 1858; in which 

 same locality I subsequently captured two specimens myself, 

 during January of the following year.
