COLEOPTERA. 
lugubris, Brsk., is a moderate-sized black species found commonly at light 
in the plains, S. indica, Blanch, has been reared from larvae feeding on 
the roots of cane in Behar and is one of the most common species. 
Macrodactilini include one species , Bejeania alsiosia, Bl., a moderate-sized 
brown pubescent species which is found in the plains in June. The 
Melolonthini include over 160 species, chiefly in the genera Apocgonia, Schi- 
zonycha, Lepidiota, Holotricha (Lachnosterna), Bramina, Hoplosternus 
and Melolontha. They are the larger cockchafers of the plains, most 
abundant in the moister areas. Apogonia carinata, Brsk., is a shiny black 
species of moderate size which is found passing the winter under the bark 
of trees. A. proximo,, Wat., is extremely like it and is found flying in 
June. A. uniformis, BL, is also common, a smaller brown species which 
comes freely to light during the rains. ScMfronycha xanthodera, Bl., is a 
larger species, which flies during March and April. Lepidiota includes 
the very large species found in forest localities as a rule ; one species 
L. rugosipennis, BL, is found in the plains, though rarely. 
Rutelince. —Lamellicorn beetles, with three spiracles on the mem¬ 
brane between the dorsal and ventral plates, three on the ventral 
plates and visible, with the claws of the tarsi of unequal size. These 
are moderate-sized insects, in general form closely similar to the 
Melolonthids. Many are brightly coloured, blues, greens and browns 
predominating, and many are sombre. 
The life-history of one species is known, this being the common 
cockchafer of the plains, Anomala various, Oliv. The stages are fully 
illustrated in Plate XIV and the details of the life-history are given in 
full elsewhere. (Mem. Agri. Dept. India, Vol. 11.) The life-history occu¬ 
pies one year ; eggs are laid in the soil in the early rains, which increase 
in size and weight after laying. The larva lives in the soil eating the roots 
of rice, bajra and other cereals. It rests in the soil from September, 
pupates in March, April or May, and the imago emerges, after about 
ten days. 
A large number of species occur in India, one subdivision, the Ano- 
malides, being distributed through the tropics, another, the Adoretides, 
abundant in India and Africa alone. Anomala with over fifty species, 
Popilia with thirty and Mimela with twenty-seven are included in the 
first; Adoretus with twenty-four species in the second. To a greater
