afternoon meeting, a detailed account of the same being after- 
wards published in the last part of the Club’s Proceedings.* I 
have now to record the capture of another specimen of the same 
insect, on the 29th October last. This specimen larger and 
finer than the former one, the length of the body exceeding an 
inch, was caught on the back of a man employed in cutting up 
blocks of wood in a timber yard, on the Bristol road. 
On the occasion of the first capture, the insect was supposed to 
be the Acunthocinus edilis, of Megerle and Stephens; but I had 
a suspicion at the time, from its larger size and more varied 
colours than those of the 4. edilis, as represented by Donovan, 
that it might prove to be a different species, and probably a 
foreigner accidentally introduced into this country. This suspicion 
has now become a certainty. There is no question as to the 
insect captured this last autumn being of the same species as 
that taken in the autumn of 1883; and on correspondence with 
Mr. Fitch, the Secretary of the Entomological Society of London, 
and Mr. Waterhouse, of the Natural History Museum, South 
Kensington—the subject having been also brought under the 
notice of the members of the above society at one of their 
meetings in December last—it has been clearly ascertained that 
both specimens belong to the genus Monochamws Serville (Ann. Soe. 
Ent., France, 1835, p. 91), and are identical with the Lamia 
dentator of Fabricius ;+ the L. titillator of that author being the 
same insect. 
Monochamus is one of the very numerous genera which have 
been made by modern Entomologists out of the old Linnean 
genus Cerambyx. The type of the genus is MW. sutor, L., a species . 
that has occasionally been met with in this country, and is 
figured by Donovan in his “ British Insects.”{ Nearly allied to 
this last is M. sartor, also a rare British species, figured by Curtis
