Mr. W. W. Saunders exhibited a collection of insects which he 
had recently received from Albania, accompanied by a series of 
notes upon the habits, &c. of the different species. 
“ Notice of the Recent Occurrence in London of Ptinus ho- 
loleucus of Faldermann.” By Mr. W. Bainbridge, M.E.S. 
This insect had been captured in some abundance by Mr. J. 
Norman, of Hoxton, and had been observed by him for several 
years past in the warehouses of an extensive brush-manufactory 
near the city. Mr. Norman not collecting Coleoptera, and supposing 
it a common insect, suffered them for a long time to pass unno- 
ticed. The insect, whether in the larva or perfect state, does not 
appear as yet to do any harm, as it confines itself to feeding on 
the skin or flesh adhering to the roots of the bristles used in 
brush-making. The bristles are chiefly imported from different 
ports in Russia, and there is little doubt but the insect has been 
introduced into this country by their means. This is in part con- 
firmed by the circumstance of Mons. Faldermann, a Russian Ento- 
mologist, having described and figured an insect in the 4th volume 
of the “ Nouveau Memoires de la Societe Imperiale des Natu- 
ralistesde Moscou,” (Tab. VII. 16,) under the name of Ptinus holo- 
leucus, so similar to these now before the Society, as to leave 
little if any doubt of their being the same species.
