Mr. T. V. Wollaston on the Halticidae 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. Longitarsus inconspicuus, n. sp. 



L. elliptico-ovatus convexus nitidus minutissime subalutaceus, capite 

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

 stincte pimctulato, elytria dilute testaceis sutura picesceuti, minus crebre 

 et profundius punctatis; antennis fusco-piceis, ad basin pedibusque 

 anterioribus testaceis, pedibus posticis paulo obscurioribus. 

 Long. corp. lin. vix |. 



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

 Maio ineunte, 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. 



13. Longitarsus fusco-ceneus, Redt. 

 Lonyitarsus fusco-ceneus, Redt.,Fna Austr. 535 (1849). 



Habitat in foliisisWm violacei, L., in ins. Fuerteventura et Teneriffa rarior, 



plerumque ima cum L. Echii degens. 



The L. fusco-ceneus was first detected in the Canary Islands by 

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

 in Fuerteventura ; and it was subsequently captured by myself in 

 Teneriffe, — both on the mountains above S ta 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.
