“ Extract from a Letter from A. M'Barnet, Esq., of St. Vincent’s, 
relative to the Ravages of the Mole- Cricket in that Island.” Com- 
municated by C. J. Johnstone, Esq. “ The mole cricket has, for 
some years, been destroying the pastures all over the Island, and 
has now, on many estates, attacked the young plants and the cane 
stools, and may probably account, in some measure, for the great 
falling off in the growth of the canes generally over the Island, 
although we were not aware of the cause. They are beginning to 
attract general attention, and probably that will lead to some me- 
thod of destroying them. I have tried many experiments. Lamp 
oil destroys them very readily, but it is too expensive on a large 
scale. Soap-suds also kill them, but not so readily. This animal 
is known in England. Can you give me any information as to the 
best way of destroying them ? I think the refuse of soap manu- 
factories, or any greasy manure, might ; soot, lime, and many other 
substances may be useful. They are under ground all day, and 
appear on the surface at night only.” 
“ Notices relative to Anobium tesselatum, Anommatus ierricola, 
Bombyx mori, and Scolytus destructor.” By W. Spence, Esq., lion. 
M. E. S., See., as follows : — 
“ Anobium tesselatum. -My attention being attracted the other 
day, in passing through one of the streets of Brussels, by the ex- 
tremely worm-eaten appearance of the ends of some large old 
oak beams, lying opposite to a house which had been entirely 
gutted in order to replace them by new ones, I stopped to ob- 
serve them more closely, and found that what had struck me was 
evidently the work of the larvae of some insect, which, on a nar- 
rower examination, I had no doubt had been those of Anobium 
tesselatum , as I detected several specimens of this species in its 
perfect state, remaining dead in the holes in which they had un- 
dergone their metamorphosis, and from some cause had not been 
able to escape. Several of the holes were visible in the upper 
angles and the beam where the joists had been inserted, but it was 
at its ends, and especially at one of them, that they chiefly 
abounded. Here for about a foot and a half of its length, and 
through nearly the whole of its thickness, which was fifteen to 
eighteen inches each way, the holes, which had about the diameter 
of a small quill, were so numerous and so close to each other, as 
exactly to resemble a honey-comb, the portion of wood that still 
divided them from each other being often scarcely at all thicker 
than the wax between two cells ; and the whole end was thus in
