(not uncommonly) out of the dried Huphorbia-stems on the moun- 
tains above S Cruz of Teneriffe, as well as in the lower regions of 
El Golfo on the west of Hierro.” A single example was also taken 
by W. D. Crotch, Esq., in Teneriffe. 
In outline and general colouring the S. annulicornis is closely 
allied to the S. Troberti of southern Europe (for the opportunity of 
examining which I am indebted to Mr. Pascoe); it may, however, 
be immediately known from it by its much larger size and longer 
antenne, by its considerably coarser sculpture and robuster pubes- 
cence, by its surface being sparingly studded all over with elongate 
erect hairs, and by its elytra being more perceptibly ornamented with 
broken, darker longitudinal lines.

Cerambyx albidus, Brullé, in Webb et Berth. (Col.) 62. pl. 1. f. 8 
(1838).

Hatitat in locis similibus ac preecedens, sed in Lanzarota, Fuerteventura 
et Teneriffa. 
The whiter and less dense pubescence of the S. albeda, in con- 
junction with its almost concolorous pronotum, its still more power- 
fully developed prothoracice spine, its less evident and more broken 
elytral lines, and its usually more perceptible (and paler) elytral 
spots, will at once suffice to separate it from the annulicornis. It is 
not uncommon beneath the dry outer bark of the various Euphor- 
bias, under which circumstances I have taken it in Lanzarote and 
Fuerteventura ; as also at Taganana, and on the mountains above 
S* Cruz, in Teneriffe. 
14. *Stencdea pilosa. 
Blabinotus pilosus, Woll., Trans. Ent. Soc. Lond. (8rd Series) i, 181 
(1862). 
Habitat Lanzarotam, in Euphorbiis emortuis, rarissima. 
The narrower outline of the S. pilosa (the elytra of which are but 
slightly wider than the hinder region of the prothorax), in con- 
junction with its much shorter and almost anguliform prothoracic 
spine and the comparatively broader anterior portion of its pro- 
thorax (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 would seem to be extremely rare, and 
confined (so far at least as has been observed hitherto) to Lanzarote,
