Phytophaga Malay ana. 129 



basilar space, the depression nearly obsolete on the inner disk, 

 broad and well marked below the humeral callus, which is pro- 

 riiinent, bounded within by a longitudinal depression ; surface 

 finely but distinctly punctured, the punctures arranged in longi- 

 tudinal rows, which approximate in pairs on the inner disk and 

 towards^ the apex of the elytron. Outer edge of intermediate 

 tibiae sinuate towards the apex. 



The green colour and the short robust form (which strongly 

 resembles that of C. rohuslus ^iw^S. its allies"), together with the finer 

 and less close punctation of the surface, and the more acutely 

 appendiculated claws, will at once separate this insect from C. Ir'i- 

 lubatus. 



34. Corynodes tr'iluhalus, n. sp. (PI. V. fig. 7.) 



Elongatus, convexus, saturate purpureas, nitidus; thorace sub- 

 conico, irregulariter profunde punctato ; elytris infra basin 

 distincte transversim impressis, fortiter subcrebre punctatis, 

 punctis seriatim dispositis, striis disci medio confusis ; an- 

 tennis clava late dilatata ; mesosterno apice trilobato. 



Long. 5 — 5\ lin. 



Hab. Pulo-Penang. 



Head coarsely punctured, front impressed in the middle with a 

 loniiitudinal groove, anterior margin continuous with the en- 

 carpae and apex of the epistome ; encarpae smooth, depressed ; 

 epistome not longer than broad, sides rounded and converging 

 backwards, surface closely punctured ; antennae considerably 

 more than half the length of the body, five upper joints broadly 

 dilated, the seventh to the ninth trigonate, gradually increas- 

 ing in width, the fifth and sixth compressed, trigonate. Thorax 

 subconic, sides nearly straight and converging from base to apex ; 

 hinder angles acute, slightly produced ; surface very deeply and 

 irregularly punctured. Elytra oblong, parallel, convex, distinctly 

 excavated below the basilar space; humeral callus prominent, 

 bounded within by a longitudinal impression ; surface rather 

 coarsely punctured, the punctures closely arranged in numerous 

 longitudinal rows, those on the middle disk irregular and less 

 distinct. Apex of mesosternum trilobate. 



Nearly allied to C. Mouhoti (mihi), from S;am, but easily dis- 

 tinguished from that species by the darker colour, narrower and 

 more parallel form, and the trilobate apex of the mesosternum.
