strongly punctate-striate, the intervals all equal and somewhat 

 costiform; the apex is more or less black. 



I believo that the species described by me as Lycus (gen. 16) 

 gracilis (Trans. Ent. Soc. 1878, pp. 99 & L07) is only a variety of 

 the abovo, having the elytra entirely yellow. 



Plateros planatns. 

 (Plato YII. fig. 1.) 



Piceo-nigcr, nitidus, pubescens ; thorace flavo, disco utrinque 



infuscato ; elytris crebre striato-punctatis, interstitiis angustis.

Hab. Shanghai {Fortune), Penang {Cantor). 



Antennae a little stouter than in the preceding species, broadest at 

 the middle, tapering towards the apex ; the third to sixth joints are 

 a little more dentate in the male than in the female. Thorax 

 shining, the sides gently reflexed, the front margin with a few 

 punctures. Scutelltim yellow. Elytra rather strongly and closely 

 punctate-striate, the intervals very narrow, nearly equal, the fourth 

 a little more elevated at the base. The inside of the base of the 

 femora yellowish. 



This species is very close to the preceding, but (besides the 

 difference of coloration) it differs in having the sides of the thorax 

 less refiexed, and the posterior angles are more rectangles. 



Plateros languidus. 

 (Plate VII. fig. 2.) 



Obscure fuscus, pubescens, parallelus, depressus ; capite flavo ; 

 thorace flavo, depresso, marginibus incrassatis vix reflexis, disco 

 foveolis quiuquc parvis impresso ; elytris crebre evidenter punctato- 

 striatis, interstitiis angustis, alternatim parum elevatis. <$ .

Hab. Ceylon {Nietner). 



Head slightly impressed between the eyes. Thorax flat, impressed 

 within the margins, with four small round fovea) on the disk and an 

 elongate mesial one behind. Scutcllum yellow. Elytra subparallel, 

 a trifle wider at the apex, distinctly and closely punctate-striate; the 

 interstices very narrow, the alternate ones a little more distinct. 



Plateros fuscipennis. 

 (Plate VII. fig. 3.) 



Elongatus, parallelus, fuscus ; thorace sordide flavo, nitido, medio 

 paulo infuscato ; elytris evidenter crebre punctato-striatis, inter- 

 stitiis angustissimis costiformibus. tf . $> • Long. 2^-3.j lin.
