400 CHRYSOMELID^E. 



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 ; 

 antennas 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. 



Length 5 mm. 



Hai. 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. 



Trichotheca, Ealy, Journ. Ent. i, 1860, p. 26; Chapuis, Gen. Coleopt. 

 x, 1874, p. 272 ; Lefev. Cat. Eumolp. 1885, p. 75. 



Type, T. hirta, 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 incrassafe, 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. 



TrichotJieca, although placed near Aotia by Baly, 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. Ent. i, 1860, p. 26, pi. i, fig. 5. 



Pale f ulvo-fuscous ; a short vitta on the disc of the thorax and 

 three patches on each elytron, black. 



Elongate ; whole body clothed with subefect, 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 ; antennas 

 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
