150 Records of the Indian Museum. [VoL. XII, 
described, and larvae found with pupae and adults in a tree prob- 
ably belonging to the genus Swretenta on the Calcutta Maidan. 
There can be little doubt, from the state of the tree when it was 
cut down, that these larvae, together with many others of the same 
species, were responsible for its death. The adults agree closely 
with Théry’s description of Cardiaspis pisciformis from Mysore 
(Bull. Soc. ent. France, 1904, pp. 73-74, text-fig. 2), the only appar- 
ent differences being that the sides of the pronotum are practi- 
cally parallel in their latter half, and that the posterior tibiae are 
straight except in one specimen and are almost imperceptibly 
curved in this. Equally great differences exist, however, between — 
Théry’s figure of C. mouhoti, Saunders, and our specimens of this 
species, and I have no hesitation in referring the specimens from 
2? Swietenta to Théry’s species. Their larvae may now be described. 
Cardiaspis pisciformis, Théry. 
(Pl. xxii, figs. 23-28.) 
Locality.—Calcutta (2? in Swietenza sp.). 
Four specimens varying in length from 23-33 mm. 
The clypeus is about 5 times as wide as long and bears a 
small but deep and clearly defined puncture on either side of the 
middle line, which is more or less faintly keeled between and behind 
them. The anterior margin is lightly concave and the anterior 
border strongly depressed laterally, the depressions being bounded 
behind by keels. 
The labrum is mounted on a membraneous peduncle. The 
labrum and peduncle are each fully as wide as the clypeus is long, 
and are together fully as long as wide, the labrum being about 
twice as long as the peduncle. The anterior and lateral margins 
of the labrum are lightly convex, the angles are rounded ; the sur- 
face is grooved in the middle line in front, this groove being sur- 
rounded by a semicircular or more or less Y-shaped groove which 
crosses the middle line behind it. The peduncle is depressed or 
grooved in the middle line. 
The antennae are three-jointed. The basal joint is large and 
fleshy, almost white in colour. The second joint is smaller and 
harder, much yellower in colour, obliquely truncate and fringed 
with short close hair distally, the truncation facing downwards. 
The terminal joint is much smaller still, the distal fringe being in- 
deed its most conspicuous part; as it is set on the oblique distal 
face of the second joint it is directed downwards. A (? sensory) 
hair arises dorsally at the base of the terminal joint ; whether this 
hair arises from the middle or terminal joint I have been unable 
to determine. The mandibles are small, tridentate distally, and 
very hard. The maxillae are weak; the blade of each is cylindri- 
cal, and is rounded and unarmed distally ; the palp is two-jointed, 
the basal joint is as large as the blade and not unlike it in shape, the 
terminal joint conical, slightly longer than it is broad at the base and 
scarcely half as long as the basal joint. The labium is even less
