Hind tibia one - spined; mid - coxas separate Coprinje. All the above subfamilies, with the exception of the Pleo-cominje, Pachypodenve, Aclopikje, Tatjrocerastii^e, and Ibio- SCARAB.El DJOi. 211 ^tomim, occur in the Indian region. Some of them are verysmall; the Idiostomin.e, lor instance, contain only one genus,and the Aclopin.e two genera. Taken as a whole they correspondto the CoPRiNiE of Sharp and other authors, and comprise a largenumber of species which vary very largely in size, from the smallspecies of Aphodius, Trox, JEqialia, etc., to the large Heliocoprisand Scarabwus. They live chiefly on dung or in and under deadanimals ; the majority prefer animal matter in a moist state, whileothers, such as Trox, are found among bones, skins, etc. In someof the species which bury masses of dung for the food of their

This is another proof of the high position attainedby the Lamellicornia. The group as a whole is largely repre-sented in India. Between the Laparostict and PleurostictScarab.eidyE come the Melolonthin.^, (tlaphyrin.e, and Oncer-iisvE ; these differ very much inter se, and Leconte and Horn foundit necessary to place the first tribe under the heading of PleurostictMelolo:ntiiin,e, and the last two under the heading of LaparostictMeloloxthiin\e. We need not here discuss the question, as 212 INTRODUCTION. neither the GlaphyrijwE nor the OxcerinvE occur in India; it is,however, worthy of notice that the GtLAPHYRin.e, contrary to allrule, have a spiracle on the pygidium, a character which isolatesthem from all the other groups.
