castor which also feeds upon the common weed, dudhi [Euphorbia piluli - 
fera. For a full account see Mem. Agric. Dept., Ent., Yol. II, No. 3. 0. 
algira, Linn., also feeds on castor but appears to be rarer. Other common 
species are, 0. serva , Fabr.; 0. illibata, Fabr. ; 0. palumba, Guen. ; 0. 
dotata, Fabr.; 0. mejanesi, Guen. ; 0. arcuata, Mo. ; 0. joviana, Cram, 
(feeds on Phyllanthus ); 0. arctotcenia, Guen. ; 0. analis , Guen.; 0. crameri, 
Mo.; 0. onelia, Guen. (feeds on Phyllanthus ); 0. coronata, Fabr. (feeds on 
Quisqualis, and has the hindwing orange); 0. trirhaca , Cram, (hindwing 
orange, feeds on guava); 0. honesta, Hubn. (hindwing crimson); and 
0. fulvotcenia, Guen., in which the male has the mid tibia cleft and 
filled with scales. The larva of 0. coronata , Fabr., is very striking, a 
very long grey-brown larva with two tiny oval tubercles, which clings 
tightly to the shoots, pressed closely against them and so being very 
difficult to see. The first we found was due to a mynah jumping from 
the ground and snapping one off a Quisqualis bush. 
Homoptera is similar, the male with heavy tufts of hair on the fore 
tibiae. It includes the two common species, H. umbrina , Guen. (Plate 
XXXIY, fig. 13), and H. glaucinans, Guen. ; Forsayeth (Trans. Ent. Soc., 
1884, p. 379), reared these species and his paper may be consulted. 
Momince comprises the genus Moma, not included here. 
Plusiince. Plusia is a large genus of which several species occur 
in the plains, some as pests. The discrimination of these species is a 
matter of difficulty as the markings are closely alike in a large number 
of species. (Plate XXXVII.) P. orichalcea, Fabr., is distinguishable 
at once by the large brassy patch on the forewing, occupying the 
centre up to the outer margin. The larva feeds on Cruciferous plants 
and is common in the cold weather ; it is green with a marked lateral 
white line and conspicuous black spines. P. agramma, Guen., is nearly 
uniformly coloured in grey-brown, the forewing with dull bronzy 
reflections. The larva feeds on Cucurbitaceous plants. (Plate 
XXVIII, fig. 13.) The remaining species have the “ Y ” mark in 
some form on the forewing and cannot be identified save from a 
comparison of specimens. P. limbirena , Guen., feeds upon indigo in 
Behar. (Ind. Mus. Notes, V, p. 162.) P. ni, Hubn., is not uncommon 
feeding upon opium, cabbage and safflower. P. signata , Fabr., feeds 
on cabbage and is an occasional pest. P. chalcytes, Fabr. (eriosoma, 
Doubl.), is common, the green larva feeding on mint and on cultivated
