captured it. In Fuerteventura, Teneriffe, and Palma it was found 

 also by Mr. Gray. As in the neighbouring archipelago, it is ex- 

 tremely variable in hue — being sometimes entirely testaceous, at 

 others with the prothoracic disc and the suture dark, whilst in 

 highly-coloured individuals nearly the whole of the prothorax and a 

 large portion of the elytra are blackened. The generaliti/ of the Cana- 

 rian specimens, however, are altogether pale, like the Porto-Santan 

 ones, — the darker states, which are the rule rather than the excep- 

 tion in Madeira proper, being comparatively rare in these islands. 

 M. Allard writes, of the P. vehemens, " Cette belle espece ressemble 

 beaucoup au P. crassicollis, Fairm., mais son corselet est un peu plus 

 court et plus etroit, la ponctuation des elytres est plus forte, et la co- 

 loration est differente."

This small Psijlliodes, which is of a brownish-pieeous hue with 

 more or less of an obscure brassy or even greenish tinge, and the 

 prothorax of which is convex, delicately alutaceous, and studded with 

 very minute and shallow punctules, is peculiar, 8o far as observed 

 hitherto, to Lanzarote and Fuerteventura — in the former of which 

 it was captured by Mr. Gray and myself, on the common Mercurialis 

 annua, during January 1858, around Haria (in which locality I 

 again met with it in the spring of the following year) ; whilst, in 

 the latter, I took it sparingly, at the end of March 1859, at Oliva.

Of the present Dibolia a single example was captured by myself 

 in Fuerteventura (I believe, in the llio Palmas), during the spring of 

 1859. It is unquestionably distinct from five of the European spe- 

 cies of which M. Allard has kindly communicated types, though per-
