. 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.
