392 CANABIAN COLEOPTEKA. 



The S. ammlicornis, the distinctive characters of which I have fully 

 pointed out in my Paper "on the Enjihorbi a -infesting Coleoptera of the 

 Canary Islands," occurs beneath the bark, and within the branches, of 

 dead Euphorbias — in which situations I have taken it on the moun- 

 tains above S*" Cruz of TenerifFe, and in the lower regions of El Golfo 

 on the western side of Hierro. A Teneriffan specimen has also been 

 communicated by Dr. Crotch. 



598. Stenidea albida. 



Ceramb^'x albidus, JBrulle, in Webb et Berth. (Col.)62. pi. 1. f. 4(1838). 

 Blabinotus albidus, JFolL, Trans. Ent. Soc. Lond. i. 180 (1862). 

 Stenidea albida, Id., Journ. of Ent.'\\. 109 (18G3). 



Habitat Lanzarotam, Fuerteventuram et Teneriffam, in iisdem locis 

 ac prascedens. 



The whiter and less dense pubescence of the S. albida, in conjunc- 

 tion with its nearly concolorous prothorax (which is free from a broad 

 pale band down the centre, and has the lateral spiae still more power- 

 fully developed), its less evident and more broken elytral lines, and 

 its usually more conspicuous elytral (punctiform) spots, will readily 

 suffice to distinguish it from the S. annuUcornis. Like that species, 

 it is found (I believe exclusively) beneath the loose outer fibre of the 

 various Euphorbias — under which circumstances I have captured it 

 in Lanzarote and Fuerteventura, as well as at Taganana and on the 

 mountains above S*''' Cruz in Teneriffe. 



599. Stenidea pilosa. 



Blabinotus pilosus, WoU., Trans. Ent, Soc. Lond. i. 181 (1862). 

 Stenidea pilosa, Id., Jmirn of Ent. ii. 109 (1863). 



Habitat Lanzarotam, in Eupho7-biis emortuis, rarissima. 



The present Stenidea would appear to be of the greatest rarity — 

 three specimens only, all of them from Lanzarote, having as yet come 

 beneath my notice. The first of them was captured by Mr. Gray, 

 during January 1858, near Haria, in the north of that island ; and 

 the other two by myself, in the same region, exactly twelve months 

 afterwards. Like the two preceding species, I believe it is strictly of 

 Euphorbia-iniesting habits. 



600. Stenidea Hesperus. 



Stenidea Hesperus, WoU., Journ. of Ent. ii. 110 (1863). 

 Habitat ins. Hierro ; die 11. Feb. a.d. 1858, exemplar unicum supra 

 folia Eumicis Innarice depi'ehendi. 



The present Stenidea is hitherto unique, the specimen described
