from tlie neighbourhood of the town, are both recognised by Mr. 
"W ollaston as imported through the medium of commerce, he having 
found them also at Madeira and the Cape Verdes in the warehouses 
and stores. They have doubtless reached St. Helena in bags of rice 
or casks of flour. 
R. pusilla, F. 
Fam. Tomicidce. 
Tomicus, Lat. 
T. aemulus, Woll. — This insect, Mr. Wollaston considers, may 
be an indigenous one ; but as I only met with one specimen, and 
have no recorded locality to it, 1 am unable to say whether it was 
taken from the high or the low land. 
Fam. Hylesinidce. 
Hylurgus, Lat. 
H. ligniperda, Fab. — A dark brown, almost black, Beetle, a 
quarter of an inch in length, very common amongst the pine or fir 
trees on the high lands, about Plantation, and other localities of 
the same altitude. It is an European insect, which, Mr. Wollaston

Canarian groups.

SUB-FAM. COSSONIDES. 
Stenoscelis, Woll. 
S. hylastoides, Woll. — An almost black, cylindrical-shaped 
Beetle, one-sixth of an inch in length, taken from the wood of 
decaying branches of trees on the high land. Mr. Wollaston says 
of it : “ The examples which I originally described of this curious 
insect, and for the reception of which I found it necessary to 
establish a new genus, were taken by the late Mr. Bewicke, in 1860, 
at the Cape of Good Hope ; and it is an interesting fact, therefore, 
geographically, that (judging from an extensive series which was 
captured by Mr. Melliss) the species would appear to be common 
also at St. Helena. After giving, in the Journal of Entomology, a 
lengthened diagnosis of the group, I added: ‘ So very closely does the 
present insect, at first sight, assimilate Eylastes, that I had regarded
