owing to the fine and transversely confluent puncturation — 

 more opaque. 



Tonkin, Chapa, May 1916 {R. Vitalis de Saloaza), 4 <? <$ , 



1 ?. 



The type is in the British Museum. 



Chjcenms vitalisi, J ? . 



Length 12-14 mm. ; width 4*25-5 mm. 



Black ; head and prothorax metallic green, elytra green, 

 darker (sometimes with faint purplish tinge) on disk ; legs, 

 first three joints of antennae (rest brown), and apex of elytra 

 flavous; palpi, margin and epipleuraj of elytra, margin and 

 apex of ventral surface yellow-red. 



Head (2*5 mm. wide) shiny, convex, minutely rugose, with 

 a few small scattered punctures, eyes prominent, antennas 

 long, joint 3 sparsely pilose, half as long again as 4, palpi 

 slender. 



Prothorax transverse (3 X 2*75 mm.) moderately shiny, 

 subconvex, truncate in front, base emarginate, widest before 

 middle, sides rounded in front, slightly sinuate behind, hind 

 angles a little obtuse and rounded, side-border very fine ; 

 median line fine, basal fovea? deep, curving behind towards 

 hind angles, surface very finely vermiculate-striate, more 

 densely near both front and hind angles, sparsely covered 

 with punctures of moderate size, basal area with some finer 

 punctures as well, middle of base longitudinally striate. 



Elytra subconvex and subopaque, nearly three times as 

 long as prothorax, widest a little behind middle, border 

 obtusely angled at shoulder, hardly sinuate towards apex, 

 punctulate-striate, with a row of minute setiferous punctures 

 (visible only when magnified) on each side of the strise, 

 intervals 8 and 9, and the apical area more visibly punctate 

 and pubescent, border dark red for first two-fifths, interval 9 

 also for next two-fifths, apex widely flavous, with irregular 

 front margin (as in C. tnops, Cliaud.). 



Underside shiny, proepisterna smooth, sides of metasternum 

 and episterna with a iew scattered punctures, prostemal 

 process unbordered, shortly pilose. Front femora without 

 tooth, upper surface of tarsi very sparsely punctate, with a 

 few minute seta?. 



Very closely allied to C. marginifer, Chaud., but differing 

 in the very fine rugosiiy of both head and prothorax, the 

 latter wider and more contracted behind, surface of elytra less 

 finely shagreened. In C, marginiftr strise 8 and y and the
