122 Phytophaga Mulayana. 



25. Corynodes ccerulealus, n. sp. 



Elongatus, convexus, subtus viridi-cyaneus, supra cseruleus ; 

 thorace transverso, subremote punctate ; elytris seriatim 

 punctatis, punctis in striis bifariis dispositis, infra basin et 

 intra callum humerale distincte excavatis ; antennis clava sat 

 dilatata, nigri; frontis margine antico trilobato, lobo medio 

 vix producto, compresso, angulato. 



Long. 3 lin. 



Hab. Pulo-Penang. 



Head coarsely but distantly punctured, front impressed with a 

 faint longitudinal groove ; anterior margin separated from the en- 

 carpae and epistome by a deep groove, trilobate, the lateral lobes 

 rounded, the medial very slightly produced, compressed and angu- 

 late, its surface, together with a triangular space above, de- 

 pressed ; epistome scarcely longer than broad, sides rounded and 

 converging backwards; surface gradually shelving off at its 

 upper portion towards the apical groove, rugose-punctate ; en- 

 carpse cultriform, their upper half thickened ; antennae half the 

 length of the body, five upper joints moderately dilated, seventh 

 to the ninth gradually increasing in width, obscure cseruleous. 

 Thorax one-fourth broader than long, sides rounded, converging 

 in front, hinder angles produced into a short tubercle ; above 

 transversely convex, sides strongly deflexed in front ; surface 

 subremotely punctured. Elytra narrowly oblong, parallel, broadly 

 rounded at the apex, convex, middle disk distinctly excavated 

 below the basilar space ; humeral callus subprominent, bounded 

 within by a longitudinal depression ; surface deeply but not 

 coarsely punctured, tlie punctures arranged in numerous longitu- 

 dinal rows, which approximate in pairs ; these pairs frequently 

 near the apex of the elytron become reduced to a single irregular 

 row of punctures ; on the outer disk, near the lateral border, are 

 several slightly-elevated costae. 



Narrower, more parallel, and more finely punctured on the 

 elytra than the preceding species; in other respects closely allied. 



26. Corynodes igneipennis, n. sp. 



Oblongus, convexus, metallico-caeruleus, viridi-tinctus, nitidus; 

 thorace transverso, subremote tenuiter punctato ; elytris 

 cupreo-aureis, anguste viridi-limbatis, infra basin transversim 

 depressis, tenuiter punctatis, punctis seriatim dispositis ;
