This is a large and very interesting family containing, so far asat present known, about 1500 species,which are extremely variable in size, shape,facies, structure and habits. Several of thegenera are well known for the difficultyattending the discrimination of theirnumerous species ; among these may speci-ally be mentioned Meligethes and Camptod-s;the difficulties, however, to a great extentvanish on a closer examination of thecharacters. Several of the genera areFig. 49.—Lordites brachypterous and closely resemble Staphy-picta. linidyE, for which they might easily be mistaken ; among these are Halepopeplus,CUlceus, Orthogramma, Ithyphenes, and Adocimus ; in fact they. 104 INTRODUCTION. can only be distinguished superficially by the shape of the antennaeand the smaller number of visible segments. One or two of thegenera, such as Calonecrus and Ctilodes, are larger and very peculiarin structure and facies. The habits of the Nitidulidje are very various. One large grouplives in flowers, while another is found at sap or at the exudationsof trees infested by boring insects; others again are found infungi, others in decaying animal substances, or under bones, whilethe cosmopolitan genus Carpophilus is found among grain, or drypreserved fruits ; the peculiar genus Amphctis is attached to antsnests. The classification of the Nitidulid;e has given rise to a gooddeal of dispute, not so much on its general points, as with regardto the inclusion or exclusion of two or three subfamilies. and Cybocephalin^e have, in the past, beenremoved from the group, but they have been rightl
