Verde archipelagos, through the medium of commerce. It is about 
the sixth part of an inch in length, and easily recognised by its 
metallic green colour. It inhabits only the low land in the neigh- 
bourhood of the town and Ladder Hill. 
Fam. Ptinidce. 
Gibbium, Scop. 
G. scotias, Fab. — Like the last, a European species, imported 
into the Island as it has been at Madeira. Its bright, dark brown, 
glass -like body, about the size of a large -pin’s head, and long thin 
legs, serve easily to distinguish it from the other Beetles. 
Fam. Anohiada;. 
Anobium, Tab. 
A. velatum, Woll. — This and the three following species, 
taken from the neighbourhood of the town, are small light-brown 
Beetles, which Mr. Wollaston recognises as importations into the 
Island, A. velatum also occurring at Madeira. 
A. paniceum, Linn., has also established itself in the Azorean, 
Madeiran, Canarian, and Cape Verde archipelagos. 
A. striatum, Oliv. — A common European insect, which, like 
the last species, has established itself in the above-named islands. 
A. confertum, Woll. — Of which Mr. Wollaston says: “Having 
do information concerning the precise places of capture of Mr. 
Melliss’ s various Coleoptera, I cannot but look with suspicion upon 
a single example of an Anobium now before me, as having, in all 
probability, become introduced into the Island, and been found by 
him in some house or cultivated spot ; yet, as it is well characterized 
by its very peculiar sculpture, and I cannot identify it with any 
member of the genus to which I have had access, I have thought it 
desirable to enunciate the species on the chance that it will be ascer- 
tained to have been undescribed.”
