Mahasena graminivora Hampson is figured here in all stages; it 
is found in rice in the plains, its case being formed of rice leaves sewn 
together with silk. The figures 
are taken from specimens reared 
in Calcutta on thatching grass. 
(Indian Museum Notes, IV, p. 
19.) We figure also the case of 
Psyche vitrea , Hmpsn., which 
feeds upon mango leaves in the 
plains of India. The moth has 
entirely hyaline wings. Most 
species have dark wings and 
are distinguishable on the vena - 
tion which is very distinct, 
and on the nature of the larval case ; no species can be considered 
as real pests, though a number are recorded upon tea in the hills and the 
last mentioned species has been found destructive to mango. We may 
also mention Acanthopsyche moorei , Heyl., found in Calcutta on 
Lagerstroemia indica, described as Babula grotei by Moore. A short 
account of this insect occurs in Indian Museum Notes, II, p. 13. The 
larvae of Chalia Doubledayi feeds on Amaltas (Cassia fistula) which 
they disfigure by eating the epidermis : specimens were sent in as being 
very destructive to this tree and killing it, being very abundant.

A small family of moths in which the proboscis is absent, and the 
male antennae are bipectinate to the apex with short branches. A single 
genus Arbela (5 species) occur s in India in the form of the familiar borer 
of lichi, bair, guava, mango, orange and other fruit trees. The larva 
may be known by the peculiar patches of excrement and silk found on 
the bark of these trees near the bore of the caterpillar, which comes out 
at night, feeds on the bark and makes this peculiar covering on the part 
it eats. The insect is a very common one in the plains, the species being 
A. tetraonis , Mo., figured here in all stages. (Plate XLY.)
