 and prominent. 



Elytra — More convex, inter- Less convex, intervals un- 



vals at apex equal. equal at apex. 



Cardiothorax puncto-striatus, n.sp. 



Elongate-oval, shining bronze with violet reflections, antennae 

 fuscous-brown, tarsi pale brown. 



Head densely rugosely punctate, especially on the vertex, where 

 the usual frontal impression is subobsolete; antennae reaching to 

 base of prothorax, 3rd joint thinner than but one and a half 

 times the length of the 4th, succeeding joints successively thicker 

 than the preceding, 11th nearly twice the length of the 10th and 

 ovate. Pronotum narrow, with greatest width in front of middle; 

 about as long as wide, narrower at base than at apex; apex 

 slightly arcuate towards the anterior angles; these widely acute 

 but not prominently advanced; foliaceous margin subobsolete, 

 bordered throughout by narrow reflexed edge. Sides very slightly 

 rounded and feebly narrowed towards base, where the angles are 

 abruptly obtuse but scarcely dentate. Base truncate. Disc 

 finely and regularly punctate; medial furrow deep and uniformly 

 channelled throughout; on each lobe of disc is a deep longitudinal 

 impression, formed by two long and deep fovea) which are nearly 

 continuous. Of these the more forward one extends nearly to 

 the anterior angles; the hinder one is curved inwards so as to 

 nearly meet the medial channel. Scutellum small, smooth, and 

 curvilinear triangular. Elytra oval, moderately convex, shoulders 

 narrowly rounded, but rendered more prominent by the almost 

 rectangular reflexed epipleurae, gradually widening towards apical 

 two-thirds, then sharply narrowing to a somewhat pointed apex; 

 finely regularly punctate-striate, with ten striae on each elytron, 

 alternate pairs meeting at apex. Intervals smooth, narrow and 

 convex (especially towards apex); the punctures in the striae
