. Bulletin. eculiar gliding movement. The perfect beetle is from one-fifth to one-seventh of an inch inlength, more elongated than the Buffalo carpet beetle, black, andclothed with minute yellowish or brownish hairs, giving the beetle ageneral brownish color, varying from light brown to dark pitchybrown. There is but one generation in a year, as indicated by thosewhich I have bred, for larvae found in June did not transform to theperfect beetle until the following May. The remedies for this pest are the same as for the Buffalo beetle. THE LARDER OR BACON BEETLE. Derrtiesies lardarius Linn. This beetle belongs to the same family as the two carpet beetlesalready described, and often proves a great pest in our houses. Thelarvae attack all kinds of food that contain fat, as roast-beef, hams, bacon, old cheese, etc., also feathers, skins, hair, bees-wax, and often prove a greut jinnoyance to the entomologist, since they jire asfond of the batlies of dried insects as of any of the above namedsnbstances.. Fig. 2. Dermcstcs lardarius Linn, a, larva; h, one o( its barbed hairs; c, beetle.(After Riley). These pernicious little beetles make their way into our houses inMay or June, and at once deposit their eggs on their favorite food ifthey can obtain access to it, or, if they find this impossible, theyfrequently lay their eggs near small openings or crevices so that theyoung when hatched may make their way in to the coveted articles offood. The full-grown larva (Fig. 2, a) is about one-third of an inch inlength, of a brownish color, tapering somewhat from the anterior tothe posterior extremity. It is clothed with long rough hairs (Fig, 2, 6), and has a pair of short curved spines on the top of the lastsegment. The perfect beetle (Fig. 2, c), is from one-third to one-fourth ofan inch in length, black, with a broad gray band across the base ofthe wing-covers, upon each side of which are three .small black spots.The under side is black with a yellowish tinge.
