28 LTCID^. 



Dark fuscous, rather dull, except the thorax, very parallel, de- 

 pressed. Antennae slender, scarcely at all dentate. Thorax reflexed 

 at the sides, deeply impressed on each side of the disk, with a slight 

 longitudinal impression in the middle of the hind margin. Elytra 

 I)arallel, rather strongly and very closely punctate- striate, the inter- 

 stices very narrovs^ and very nearly equal ; the shoulders are tinted 

 with dull yellow. 



In the Museum collection there is a single specimen from India, 

 in bad condition, of a species closelj' allied to the preceding. It 

 differs in having the antennae decidedly more dentate and not quite 

 so long, and the thorax is not so much impressed on the sides of the 

 disk ; the punctate striae of the elytra are not quite so strong. It 

 is a male, and measures 2^ lines. 



Plateros expletiis. 



(Plate VII. fig. 4.) 



Fuscus, pubescens ; ore, thorace, elytris femorumque basi sordide 

 flavis ; thorace nitido, margine antico rugoso-punctato ; elytris 

 crebre, sat fortiter punctato-striatis, interstitiis angustissimis, vix 

 conspicuis. J . Long. 2^ lin. 



Hah. Borneo, Sarawak {Wallace). 



Antennae fuscous, rather long and slender, scarcely dentate ; the 

 apical joint a little paler ; the third joint as long as the fourth. 

 Eyes very large, black. Thorax impressed on each side of the disk, 

 the anterior margin rather strongly (but obscurely) punctured. 

 Scutellum yellow. Elytra closely punetate-striate ; the interstices 

 very narrow, only distinct at the base, lost among the punctuation 

 at the apex, the extreme apical margin dusky. Coxae and the base 

 of the anterior and intermediate femora yellowish. 



Plateros carhoiiarius. 



(Plate VII. fig. 5.) 



Nigro-fuscus, parce pubescens, subparallelus ; thorace flavo, medio 

 fusco, nitido ; elytris sat fortiter punctato-striatis, interstitiis angus- 

 tissimis, subaequalibus. S • Long. 3 lin. 



Hah. India? 



Very close to P. fascipcnnis, from which it differs in being more 

 elongate ; the thorax is relatively a little longer and nearly parallel 

 at the sides, not so deeply impressed on each side of the disk, and 

 the fuscous disk is more distinct, only leaving the borders yellow ; 

 the punctuation of the elytra is also more rugose and less regular ; 

 there is no trace of yellow on the shoulders.
