minuta—quoting it, however, subsequently, in 1792, as the Callidium 
pygmeum. It has probably been naturalized from more northern 
latitudes in these islands, where it occurs in precisely similar spots to 
those in which it occurs for the most part in Europe. It appears to 
be more particularly attached to the various kinds of wicker- and 
basket-work, within the dried sticks of which it resides, and is con- 
sequently more often to be met with in, or about, houses than else- 
where. In such positions I took it abundantly in Palma (particu- 
larly at the Souces, towards the north-east of that island, emerging 
from its perforations in the light open trays in which silkworms were 
kept), during May 1858 ; and I likewise found it, at the beginning of 
April of the following year, in the Rio Palmas of Fuerteventura. A 
single specimen has also been communicated by W. D. Crotch, Esq., 
which was captured by himself, during the spring of 1862, in Gomera. 
It occurs sparingly in the Madeiran group ; and I may state that, 
in a paper on ‘ Additions to the Coleoptera” of those islands, pub- 
lished in the ‘ Ann. of Nat. Hist.’ for December 1858, I cited it, by 
mistake, as the Obrium brunneum, Fab., which, however, is a totally 
different insect.

This curious Longicorn, which I have fully described in my paper 
“on the Huphorbia-infesting Coleoptera of the Canary Islands,” is 
quite peculiar to the Euphorbias, within the dead branches and 
stems of which it undergoes its transformations. In such situations 
I have taken it on the hills above S* Maria Betancuria (in the Rio 
Palmas) of Fuerteventura, as also in Teneriffe—particularly on the 
mountain-slopes beyond S* Cruz, in the direction of Laguna and 
Las Mercedes. But it will probably be found to be widely spread 
over the archipelago, if only searched for in its proper localities. 
The LZ. gibbum is certainly a good deal allied to my Madeiran genus 
Deucalion, with which indeed I had at first imagined that it might 
perhaps be associated ; nevertheless Mr. Pascoe, who has lately ex-
