amined the two insects critically, assures me that he believes them 
to be the exponents of distinct groups. 
Genus SrenrpEA. 
Mulsant, Coleopt. de France, (Lamell.) Suppl. (1842). 
In their cylindrical bodies, obscurely dappled surfaces, and late- 
rally-spinose prothorax, the insects enumerated below have so much 
the primd facie aspect of the Blabinoti, that, in a paper published 
last year “on the Huphorbia-infesting Coleoptera of the Canary 
Islands,” I actually cited them as such. I should add, however, that 
I contented myself with their mere superficial contour, without even 
looking at all to their real structural characters, which the more 
recent, and more accurate, observationst of Mr. Pascoe have lately 
called attention to. It may be sufficient, therefore, here to state 
that their deflexed head and more deeply emarginate and less pro- 
minent eyes, in conjunction with the apically-acute (instead of 
securiform) last joint of their palpi, and their very much longer an- 
tenn, will serve at once, apart from minor differences, to separate 
them from the Blabinoti. 
12. *Stenidea annulicornis. 
Cerambyx annulicornis, Brullé, in Webb et Berth. (Col.) 62, pl. 1. 
f, 3 (1838). 
Blabinotus annulicornis, Woll., Trans. Ent. Soc. Lond. (8rd Series) 1. 
179 (1862). 
Habitat in Teneriffa et Hierro, intra caules Euphorbiarum degens. 
In my paper above referred to, I remarked that “the present 
species and the following one are very nearly allied, both in size and 
external contour; nevertheless the annulicornis may be known from 
the albida by the much yellower hue of its (denser) pubescence, by 
its head being more brightly variegated, and its pronotum broadly 
pale down the centre—the sides being dark. Its elytra, also, have 
a much less tendency for the small, rounded paler spots which are 
generally pretty evident in that insect ; whilst, on the other hand, 
the darker longitudinal lines are somewhat more evident, and usually 
less broken. Its surface, likewise, beneath the pile, is more rufo- 
piceous; and its lateral prothoracic spine, although large, is rather 
less powerfully developed. The annulicorms appears to be more 
abundant in the western islands than in the eastern ones, of the 
Canarian group. At any rate I have not observed it hitherto in 
Lanzarote, Fuerteventura, and Grand Canary ; but have captured it 
t Proce. Ent. Soc. Lond. 88 (1862).
