where it was first detected by John Gray, Esq., during January 
1858, near Haria, in the north of that island. Subsequently I my- 
self captured two examples of it in the same district, from beneath 
the dead, loosened bark of old Huphorbia-stems. 
15. *Stenidea Hesperus, n. sp. 
S, angusto-cylindrica, pilis demissis cinereis densissime tecta et longiori- 
bus suberectis in prothorace necnon elytrorum apicem versus parcissime 
obsita ; prothorace ad latera spina media parva armato, antice et postice 
subeequaliter constricto; elytris lineis fractis nigrescentibus sat di- 
stinctis longitudinaliter ornatis, ad apicem singulatim rotundatis ; an- 
tennis longissimis, 
Long. corp. lin. 53. 
Habitat ins, Hierro; specimen ex arbuscula quadam Rumicis Lunarie in 
inferiore vix supra mare crescente, die 11. Feb. a.p. 1858, collegi. 
At first sight the present Stenidea a good deal resembles a minute 
specimen of the S. pilosa; nevertheless, apart from its much smaller 
size, it may readily be known from that species by the more defined 
and less anguliform (though small) spine of its rather less basally- 
constricted, concolorous prothorax; by its more cinereous (or less 
yellowish-white) pubescence, and its freedom (except at the apex of 
the elytra and very sparingly on the prothorax) from additional erect 
hairs; by its elytra being more rounded-off (separately) at their tip, 
and more conspicuously ornamented with broken longitudinal darker 
lines ; and by its antenne being considerably longer. The specimen 
from which the diagnosis has been compiled is unique, and was 
beaten, on the 11th of February 1858, from off a bush of the Rumex 
Lunaria, in the island of Hierro, at a low elevation (scarcely above 
the sea-level), on the ascent from Port Hierro to Valverde.

Habitat in Canaria, Teneriffa et Palma, presertim ad flores Carduorum, 
tempore vernali et zstivo haud infrequens. 
The A. Cardui of southern Europe and northern Africa is widely 
spread over the Canarian archipelago, where it occurs, at inter- 
mediate elevations, during the spring and summer, principally on the 
flowers of thistles. I have taken it throughout the region of El 
Monte in Grand Canary, at Las Mercedes in Teneriffe, and in Palma.
