Phytophaga Malayana. 107 



the inner and lower edge of this depression, placed on the basilar 

 space, is sometimes a small tubercle; surface strongly punctured, 

 the punctures arranged (although somewhat irregularly) in nu- 

 merous double longitudinal rows; alternate interspaces on the 

 hinder and outer disks obsoletely thickened, two close to the 

 lateral margin distinctly costate. 



8. Corynodes citpreatus, n. sp. 



Anguste oblongus, convexus, cupreus ; thorace transverso, sub- 

 crebre punctato ; elytris infra basin et intra callum hume- 

 rale excavatis, subcrebre punctatis, punctis in striis bifariis 

 confuse dispositis, interspatiis disco exteriori costatis ; anten- 

 nis dimidio corporis vix longioribus, clava anguste dilatata, 

 nigro-purpurea ; frontis margine antico obtuse rotundato.

This species agrees so closely with C. hiserialus that a detailed 

 description is unnecessary. 1 shall therefore only point out the 

 differential characters between the two species ; in C. cuprealus 

 the anterior margin of the front is obtusely rounded, not produced 

 in the middle, and not sinuate on either side ; the antennae are 

 shorter, scarcely exceeding half the body in length ; the thorax is 

 more transverse, less narrowed in front, the sides being less ob- 

 liquely deflexed ; lastly, the elytra are much less regularly punc- 

 tured, the double rows of punctures being less distinct and (on the 

 middle disk) almost entirely obsolete. Both species may be 

 known from their congeners by the transverse closely punctured 

 thorax.
