12. Colaspoides vindimarginata, n. sp. 



Late oblonga, convexa, subtus rufo-picea, aeneo-micans, supra 

 viridi-aenea ; antennis fulvis, extrorsum nigris ; elytris sub- 

 crebre irregulariter seriatim punctatis, roseo-aeneis, anguste 

 viridi-limbatis. 



Long. 2 lin. 



Hab. Borneo. 



Head coarsely but distantly punctured ; epistome triangular, 

 sides nearly straight and converging, apical suture obsolete ; 

 anterior margin armed with two short obtuse teeth ; surface ob- 

 lique and nearly impunctate on its lower half, very coarsely and 

 somewhat closely punctured on its upper portion, supra-orbital 

 groove distinct, longitudinally sirigose ; encarpse and lower 

 portions of epistome golden-aeneous; antennae filiform, equal 

 to the body in length, five lower joints, together with the 

 labrum, fulvous. Thorax more than twice as broad as long, sides 

 rounded, converging in front ; transversely convex, sides strongly 

 deflexed in front, surface distinctly punctured. Elytra not much 

 broader than the thorax, somewhat closely covered with irregular

13. Colaspoides insignis, n. sp. 

 Late ovata, convexa, subtus picea, nitida, supra viridi-aenea ;

Vertex nearly impunctate ; supra-orbital groove moderately 

 impressed, coarsely punctured ; epistome subcampanuliform, apical 

 border obsolete ; anterior margin armed with two short obtuse 

 teeth, the space between them concave ; surface coarsely punc- 

 tured ; antennae filiform, slightly thickened towards the apex, 

 five lower joints fulvous. Thorax more than twice as broad 

 as long ; sides rounded and converging from base to apex, 

 more obliquely converging before the middle ; surface finely but 

 distinctly punctured. Elytra not depressed below the basilar 

 space, finely but deeply punctured, the punctures arranged very 

 indistinctly in numerous longitudinal rows, which have a tendency
