In the the last tergite and sternite nre of similar shape, and their posterior edges exactly coincide with each other; Avhereas in the the last tergite is a little more produced and ntteiuiated than the corresponding ventral segmenr, and so is plainly A'isible wlien the insect is looketl at from beneath. The last ventral segment is studded w ith stiff erect spines as in the , and the arrangement of these spines seems to differ according to the species, and to aft'ord an important means of identification, although they do not appear, as a rule, to form the regular longitudinal lines so comuionly seen in the Melolonthin^. With the exception of the comparatively small section of the Pakasxashni, the of the Indian Eegion may he assumed to be practically all root-feeders in the larval, and leaf- feeders in the adult, stages. The Parastasiini feed, in the larval stage, upon dead and decaying wood (we have no information as to the habits of the matiire insects), and are of no significance economically : but the rest must be considered as ;ill injurious to A'egetation, and so, potentially at least, to ngiiculture. The records of ii^juiy done liy them to crops in India are not at present numerous, but
