Coleoptera of the Canary Islands. 179 



but since tlie name of Stenidea had already been preoccupied and 

 that o^ Deroplia is unpublished, it follows that Blah'motiis h the 

 title by which it must be quoted. Concerning its affinities, 

 M. Thomson writes : " It belongs, in my opinion, to the Saper- 

 ditce, near to Hebestola of Blanchard ; some Hebestolas have the 

 prothorax armed, like Blabinotus." Nearly all the Longicorns 

 which I would regard as unquestionably indigenous to the At- 

 lantic islands are members of this particular group. It was 

 enunciated by myself in 1854, for the reception of an insect (the 

 B. spinicollis) found in the laurel-woods of Madeira, and which I 

 subsequently captured at the Canaries also, — in the laurel-regions 

 of Palma and TenerifFe. In 1856 another exponent was added 

 by Mr. Bewicke, — discovered beneath the bark of pine-trees at 

 the Palmeira, above Funchal ; which species I described, in 1857, 

 under the name of B. Bewickii. In January, 1858, a third repre- 

 sentative (the B. pilosus, characterized below) was detected by 

 Mr. Gray, during our residence in the north of Lanzarote, — a 

 locality in which I afterwards met with two specimens of it myself. 

 In February of the same year, whilst visiting the island of Hierro 

 in Mr. Gray's yacht, the " Miranda," 1 brushed a fourth (the 

 B. Hesperus, — as yet unpublished) from off a large bushy Rumex 

 on the ascent from Port Hierro to Valverde. And in the follow- 

 ing June, whilst breaking open a rotten cone of the Pimis canari- 

 ensis in the island of Palma, I brought to light a fifth, — closely 

 related to (but quite distinct from) the Madeiran B. Bervickii ; 

 whilst the two insects recorded by Brulle as Ceramh'ices, and re- 

 characterized in this Paper, will raise the number of Blahinoti 

 hitherto observed in the Atlantic Groups to no less than seven. 

 Thus, whilst the three here enumerated would appear to be pecu- 

 liar to the Euphorbias, two, on the other hand, are attached to 

 the pines, and one no less exclusively to the laurels. As for the 

 unique specimen from Hierro, of the B. Hesperus, though taken 

 from off a Rumex, I am scarcely in a position to draw any con- 

 clusion respecting its mode of life.
