They may be destroyed at that time, however, by the application of the kerosene emulsion diluted ten times, or by the whale-oil soap used at the rate of one pound in four gallons of water. Perhaps no insect is better known than the " bed-bug," Acan- thia lectularia, which occurs, especially in hotels, throughout the country. It is wingless, very much flattened, broadly oval in shape, and red brown in color. It is able to crawl into the narrowest crev- ices, and no bedstead has yet been made which does not aiTord it shelter. It is nocturnal in habit, seeking its prey at night and occasionally making life miserable. Where a house be- comes thoroughly infested, specimens are found under baseboards, beneath loose paper, in cracks in the plaster, and in fact wherever there is an open- ing large enough to insert the blade of a thui knife. Thev multiply rapidly and are able to do without food for a considerable period. In houses that have been long abandoned, bed-bugs of all sizes may sometimes be found, perfectly transparent as if they had been always with- out food. It is probable, therefore, that they are able to subsist upon some substance other than human blood. Where they are accidentally introduced into a house and confined to beds, there is nothing better for use than kerosene or gasoline. It should be liberally applied in joints, crevices, and wherever there is the least opening, so as to reach the bottom before the material soaks into the wood. A single thorough application of this kind usually proves successful, although it would be better to renew it a week afterward, to reach forms that have hatched from eggs since the previous application : for in
