 each angle. Legs light; anterior femora not dilatate in middle, 

 a row of punctures on posterior side near lower margin; anterior 

 tibiae slender, exterior ridge with two small rather prominent teeth

C. strratipes has a strong general resemblance to 6'. Icevigatum, 

 Macl., from which the tridentate anterior tibiae at once dis- 

 tinguish it. It is allied to C. lobatum, SI., from which it differs 

 by facies ; inflexed margins of the elytra purple ; frontal 

 sulci more divergent and deeper posteriorly; prothorax with 

 anterior angles more advanced, posterior angles more rounded, 

 basal lobe less developed; elytra shorter and wider. 



Carenum tumidipes, n.sp. 



Robust, convex; head large, with one supraorbital puncture on 

 each side, frontal sulci 'divergent; prothorax transverse, lobate, 

 with three marginal punctures on each side; elytra oval, bipunctate 

 towards apex; anterior femora swollen on lower side, anterior 

 tibiae tridentate, posterior tibi?e stout — not thick and incrassate. 

 Head, body and legs black; prothorax black on disc, widely mar- 

 gined with green laterally; under parts tinged with green; elytra 

 green— including inflexed margins. 



Head transverse, subquadrate (5 x 7'2 mm); frontal sulci deep, 

 diverging strongly backwards ; clypeus strongly declivous to 

 labrum, median part wide, truncate, intermediate angles prominent, 

 short, triangular; preocular sulcus well marked; preocular process 

 small; eyes reniform, not prominent. Antennae filiform, stout, 

 lightly compressed. Prothorax wide (5 - 3 x 9-2 mm.), convex, 

 declivous to base; sides subparallel in middle; anterior angles 

 lightly advanced, wide, obtuse; posterior angles widely rounded: 

 base with a light wide sinuosity on each side of the rounded lobe; 

 border strongly reflexed ; basal area defined by a transverse-
