150 Mr. T. Venioii Wollaston on the Euphorbia-infesting 



in the rotten branches of the various Euphorbias, on tlie Risco 

 (above the Salinas), in the north of Lanzarote ; and two examples 

 were subsequently captured by Mr. Gray in the island of Hierro. 

 In February and May of the following year I took it, in similar 

 spots, on the mountains above Sta, Cruz of TenerifFe — but, also, 

 very sparingly. It appears, like the Europs impressicollis, with 

 which it lives in company, to be confined entirely to the Euphor- 

 bias — in most of the species of which I have observed it, except 

 the E. cnnariensis. At first sight it so nearly resembles its asso- 

 ciate that it might be easily mistaken for it ; and it is possible, 

 therefore, that we may have occasionally overlooked it amongst 

 the specimens of that insect.

I have been compelled to query this insect simply because I 

 have not now the types of the L. clavicollis, in my possession, for 

 comparison : but I believe that it is strictly identical with the 

 Madeiran species ; and I think it is not unlikely, moreover, that 

 the L. vermiculatus, of the " Insecta Maderensia," will prove to 

 be, after all, but a small state of the clavicollis. Be this, however, 

 as it may, the present insect is universal throughout the Canarian 

 archipelago, on all the islands of which I have captured it, except 

 Gomera (where, nevertheless, it must doubtless exist likewise). 

 I have taken it from beneath the loose bark of the various Euphor- 

 bias in Lanzarote, Fuerteventura, Grand Canary, Teneriffe, Palraa 

 and Hierro; and even on the little island of Lobos, in the Bo- 

 cayna Strait. It may be known by its very parallel outline 

 (especially of the female sex, in which the head is not at all
