Andrewes' collection. Division V. ADOKETINI. The beetles comprising this division are characterized by their generally small size and dull, unattractive colour, almost invariably pccompauied by a clothing of short hairs or setae above as well as beneath. They are nearly all nocturnal in their habits, destroying the foliage of trees and shrubs, and frequently attracted into houses by light. The group is peculiar to the Old World and confined to tropical or subtropical regions. Although there is considerable resemblance between the Adoretini and certain Anomalini, it is quite superficial, lor the structure of the mouth is very different. In the present group. Fig. 59.—Labniin of:—a, Trigonosfomum; b, Adoretus; c, Scaphorrkin- adorctus ; d, Prodoretus ; e, FachyrrJiinadoretus. the labrum, instead of being simply a horizontal lip roofing the mouth-cavity, is produced downwards in front so as to present a very evident anterior face, which in a few species is rectangular in shape, in others ti-iangular, the apex of the triangle applied to the front edge of the mentnm ; but in the great majority it is much more highly developed, the free lower edge being produced as a long recurved rostrum across the mouth, which it completely divides into two halves, the extremity of the rostrum interlocking with, or lying upon, the front edge of the mentum. The result of this remarkable conformation is that the mandibles, and apparently the maxillae also, are incapable of meeting, as in practically all other insects, but work instead against the right and left sides respectively of the labrum.
