(Musca domestica), the currant- worm (Nematus ventricosus), oyster- 
shell bark-louse (Aspidtotus conchiformis), several species of plant- 
_ lice (Aphides), the cockroach (Blatta orientalis), the croton-bug 
(Ectobia germanica), the meal-worm (Tenebrio molitor), the grain- 
weevil (Sitophilus granarius), the bee-moth (Galleria cereana), the 
codling-moth of the apple (Carpocapsa pomonella), the cabbage- 
moth (Plutella cruciferarum), the carpet-moth (Tinea tapetzella), 
the clothes-moth (Tinea vestianella), the fur-moth (Tinea pelio- 
nella)> the currant borer (Ægeria tipuliformis), and within the few 
past years, the asparagus-beetle (Crioceris asparagi), and the well- 
known destructive cabbage-butterfly (Pieris rape). All of these, 
and the formidable list might be greatly extended, we have 
received from Europe, while very few of our native insect pests 
have been sent in return. Should our late exportation of the 
Colorado potato-beetle (Doryophora decemlineata), prove as in- 
jurious in Europe as in this country, which there is much reason 
to doubt, we shall still be very far from having made a commen- 
surate return. While the few American species which have been 
introduced in Great Britain and on the continent have not spread 
to any great extent, in almost every instance where injurious in- 
-sects have been brought thence to this country, their number and 
their ravages have been greatly increased. Thus, while the re- 
cent advent of the Axthrenus scrophularig has brought consterna- 
tion in many of our homes, we have been unable to find any 
record of its preying upon carpets, or other woolens, in the Old 
Worid, where it has been so long known. Even special inquiry 
made by me of one of the leading Entomologists of Europe, has 
failed to elicit any such information. It is said there to infest 
dried meats and similar substances. Perhaps its fondness for 
carpets is a new taste which its transportation hither has developed.
