(3) The antenna does not gradually increase in thickness 
towards the apex. 
As these characters are not present in the specimens before 
me, they cannot be made generic characters. 
One of the secondary sexual characters of this genus isa 
semilunate depression on the last abdominal sternite of the female. 
The depression varies in different species. Judging from this 
character, M.saundersi, Baly (one example in British Museum) 
is a female, and the imperfect specimen (British Museum) is also 
a female, but the depression being different, its identity as M. 
saundersi (Cist. Ent. II, 1879, p. 405) is doubtful. Besides, the 
elytra of the imperfect Macrispa is rufous and subnitid, whereas 
M. saunderst has opaque fulvous elytra.

Macrispa krishnalohita, n. sp. is distinguished from M. saun- 
derst, Baly, by the following characters :—

3. | Thorax suddenly constricted in front. ; Thorax less constricted in front. 
4. | Colour of elytra subnitid, rufous. | Elytra opaque, fulvous. 
5. | Semilunate depression on the last | The depression narrower.

Type in Mr. Andrewes’ collection, London. 
Co-type in the Indian Museum, Calcutta. 
Fuller description. 
Head.—Surface rugose, coarsely aud deeply punctate, a deep 
groove from the vertex running along the middle line; 7 proximal 
joints of the antennae with coarse and elongated punctures and 
shining, 4 distal joints covered with a bloom, apical joint 
pointed, apices of all joints (except the last) impunctate and 
shining. Mouth parts covered with fulvous hairs. 
Prothorax quadrate, abruptly narrowed in front, anterior 
angles obtuse and rounded, sides parallel, their margins slightly 
1 The specific name is derived from two Sanskrit words: krishna = black, 
lohita = red, thus indicating the two colours of the insect.
