Mr. T. V. Wollaston on the Halticidse of the Canary Islands. 9 



places around Haria (especially, I think, from off the Mercurialis 

 annua, L.), during January of 1858 ; and I subsequently captured 

 it in the same locality during March of the following year. But it 

 is the only region in which I have hitherto observed it throughout 

 the Canarian group. 



12. Longitarsiis inconspicxms, n. sp. 



L. eUiptico-ovatus convexus nitidus minutissime subalutaceus, capite 

 dilute piceo, prothorace angustulo longiusculo piceo crebre et sat di- 

 stincte punctulato, elytris dilute testaceis sutura picescenti, minus crebre 

 et profundius punctatis; antermis fasco-piceis, ad basin pedibxisque 

 anterioribus testaceis, pedibus posticis paulo obscurioribus.

Habitat locos editiores Tenerifife, in montibus supra " Agua Mansa " 

 Maio ineimte, a.d. 1859, a meipso captus. 



The single specimen described above was captured by myself, at 

 the beginning of May 1859, in TenerifFe, on the mountain-slopes 

 midway between the Agua Mansa and the Cumbre, more than 5000 

 feet above the sea. It very much resembles the European L. thora- 

 cicus, Steph., of which it may perhaps be but a geographical state ; 

 nevertheless, since M. Allard, to whom I lately transmitted it for 

 inspection, believes it to be distinct therefrom, I have treated it 

 accordingly. It seems to differ principally from that species in its 

 smaller size and larger punctuation.

Habitat in foliis Echii violacei, L., in ins. Fuerteventura et Teneriffa rarior, 



plerumque una cum L. Echii degens. 



The L. fusco-ceneus was fii'st detected in the Canary Islands by 

 Mr. Gray, who took three specimens of it near Puerto de Cabras 

 in Fuerteventui'a ; and it was subsequently captured by myself in 

 Teneriffe, — both on the mountains above S'® Cruz and at the Agua 

 Garcia. It occurs principally on the leaves of the Echium violaceum, 

 L., and, for the most part, in company with the L. Echii.
