Phytoplwga Malayana. 101 



latter distinctly raised into an oblong ridge ; surface closely 

 covered with coarse punctures ; on the disk of each elytron are 

 three or four obsoletely raised longitudinal vitta? ; in the $ the 

 elytra are covered vviih numerous strongly raised tubercles, placed 

 in about eight lonaitudinal rows ; these become obsolete on the 

 hinder third of the surface, with the exception of the outer row 

 but one, which extends the whole length of the elytron, and is 

 terminated at the suture by a large obtuse tuberosity ; outer edge 

 of intermediate tibiae sinuate near the apex ; claws appendicu- 

 lated. 



Not having retained the genus Corynoe'ides, founded by the Rev. 

 H. Clark on the present insect, I have been obliged to change his 

 specific name tuberculatus, the same having been previously used 

 for another species (post, p. 103).

Head somewhat coarsely but not very closely punctured, im- 

 pressed in the middle with a deep longitudinal groove, anterior 

 margin of front separated from the encarpse and epistome by a 

 deep groove, angular, sinuate on either side, lateral angles dis- 

 tinct ; epistome wedge-shaped, sides rounded and converging 

 tovvards the apex; surface closely punctured, encarpse cultri-

 in length, the five upper joints slightly compressed and very nar-

 than a third broader than long, sides nearly parallel, rounded and 

 converging in front, extreme edge of lateral border finely crenu- 

 late ; upper surface transversely convex, sides deflexed in front,
