CH11YSOMEL1DJE. 
707. Pseudaoria caerulea, sp. n. 
Metallic blue or violaceous ; antennae, tibiae and tarsi black ; 
basal joints of antennae fulvous ; breast and abdomen black. 
Head rather closely and strongly punctured ; labrum black ; 
antennae nearly as long as the body, third joint scarcely longer 
than the second, both short, fourth and following joints elongate. 
Thorax similar to that of P. burmanica , and punctured like the 
head. Elytra scarcely perceptibly depressed below the base near 
the suture, closely and strongly punctured in rows, interstices 
only transversely rugose at the sides, very sparingly pubescent. 
Legs very elongate and slender. 
Lem jili 5 mm. 
Bab. Manipur (Coll. Brit. Mus.). 
Distinguished from the preceding species by the metallic blue 
colour and the short third joint of the antennae, also by the 
entirely different sculpturing. 
Genus TRICHOTHECA.

x, 1874, p. 272; Lefeo. Cat. Eumolp. 1885, p. 75. 
Type, T. Tiirta, Baly, from India. 
Range. India. 
Body elongate, subcylindrical, pubescent ; antennae filiform, 
nearly as long as the body, third joint shorter than the fourth. 
Thorax subcylindrical, lateral margins absent. Scutellum tri- 
gonal. Elytra much wider than the thorax at base. Legs rather 
elongate, slender; anterior femora incrassale, strongly toothed 
beneath ; intermediate femora with small tooth ; tarsi slender, first 
joint as long as the following two united ; claws with distinct tooth 
at base. 
Trichotheca, although placed near Aoria by Balv, has very little 
in common with that genus; shape, pubescence and structural 
characters are quite distinct, and instead of being ovate and 
convex, the species are elongate and narrow. They form with 
several other genera a group by themselves. 
708. Trichotheca hirta, Baly, Journ. Bnt. i, 1860, p. 26, pi. i, fig. 5. 
Pale ful vo-fuscous ; a short vitta on the disc of the thorax and 
three patches on each elytron, black. 
Elongate ; whole body clothed with suberect, concolorous hairs. 
Head shining, remotely punctured, sparingly pubescent; clypeus 
transverse, separated from face by a deep groove which runs across 
between the insertion of the antennae; mandibles black; antennae 
nearly equal in length to the body, third joint two-thirds the length 
of the fourth. Thorax slightly broader than long, subcylindrical, 
slightly flattened above, sides rounded, sinuate behind the middle, 
posterior angles produced into an obtuse tooth, surface covered 
with large deep punctures Scutellum trigonal, sides slightly
