544 Eev. H. S. Gorham's notes on the 



square pitchy-black patch ; the elytra are pale brick-red, the costae 

 (nine in number) very even ; the scutellum is black, rather long. 



This insect is also allied to L. dehilis, Waterli., a 

 species from ChiDa, but differs from it in not having the 

 alternate costse raised. It has long been known to me 

 from a female specimen in my own collection : there are 

 three male and one female specimens. Probably from 

 the N. E. frontier, in the Calcutta Museum, and I have 

 seen one in the British Museum. 



2. Lyponia sp. ?. 



A single female specimen in the Mus. Calc, of a 

 distinct species, smaller, with the thorax rufous only at 

 the sides, and shorter and scarcely serrate antennae.

3. Plateros fuscicornis, n. sp. 



Pallide ochraceiis, abdomine, antennis, tibiis, tarsisque fiiscis 

 prothorace oblongo-qiiadrato, disco iitrinque foveolato. Long. 

 9—11 mm., (? 2 . 



Hah. Andaman Isles (Mus. Calc). 



The head, thorax, elytra, scutellum, femora, body beneath 

 (except the abdomen), and the basal joint of the antennas in part, 

 are pale ochraceous yellow. The striae of the elytra are quite even, 

 and the very short scaly pubescence almost conceals the punctures. 

 The thorax is shining : in addition to the rather deep biat wide 

 channel there is a transverse impression behind the frontal carina, 

 and a very distinct, round, almost punctiform, fovea on each side. 

 The legs are rather indeterminate in colour, being yellow at the 

 base, and become fuscous at the tarsi. 



Several specimens. 



This is very near P. languidus, but much larger.
