^tomim, occur in the Indian region. Some of them are very 

 small; the Idiostomin.e, l'or instance, contain only one genus, 

 and the Aclopin.e two genera. Taken as a whole they correspond 

 to the CoPRiNiE of Sharp and other authors, and comprise a large 

 number of species which vary very largely in size, from the small 

 species of Aphodius, Trox, JEqialia, etc., to the large Heliocopris 

 and Scarabwus. They live chiefly on dung or in and under dead 

 animals ; the majority prefer animal matter in a moist state, while 

 others, such as Trox, are found among bones, skins, etc. In some 

 of the species which bury masses of dung for the food of their

larvae, the mother survives and sees the growth of her young to 

 the perfect state, and then produces another generation (v. Sharp, 

 I. c. p. 107). This is another proof of the high position attained 

 by the Lamellicornia. The group as a whole is largely repre- 

 sented in India. Between the Laparostict and Pleurostict 

 Scarab.eidyE come the Melolonthin.^, (tlaphyrin.e, and Oncer- 

 iisvE ; these differ very much inter se, and Leconte and Horn found 

 it necessary to place the first tribe under the heading of Pleurostict 

 Melolo:ntiiin,e, and the last two under the heading of Laparostict 

 Meloloxthiin\e. "We need not here discuss the question, as
