Type in the British Museum. 



Chlcenius tudicus, $ $ . 



Length 12*5 mm. ; width 4*5 mm. 



Black ; head and prothorax metallic green, disk of latter 

 faintly suffused with copper-red, elytra brown-black on disk 

 as far on eacli side as stria 5, green at sides (in the two 

 Kanarese specimens the prothorax and sides of the elytra are 

 blue-green) ; legs, antennae, palpi, epipleuras of elytra, and 

 margin of ventral surface testaceous red ; labrum and border 

 of elytra red- brown. 



Head smooth, shiny, faintly strigose near eyes, with a few 

 small punctures at sides ; eyes prominent, antennas and palpi 

 slender, former with joint 3 hardly longer than 4. 



Prothorax quadrate, a third as wide again as head, only a 

 little wider than long, more contracted in front than behind, 

 widest rather before middle, sides narrowly bordered, faintly 

 sinuate before hind angles, which are obtuse though very 

 little rounded, the sides of the base advancing towards them; 

 median line fine, not nearly reaching extremities, basal foveas 

 rounded and deep, surface shiny, convex at sides, covered 

 with few but coarse setiferous punctures, irregularly disposed. 

 Elytra elongate-oval, a third as wide again as prothorax 

 and nearly three times as long, border with an angle at 

 shoulder, punctate-striate, intervals rather flat, the whole 

 surface finely aciculate-punctate and pubescent, the punctura- 

 tion rather closer at sides. 



Underside shiny and nearly smooth, metasternum and 

 episterna moderately punctate, sides of ventral surface sparsely 

 punctate and pubescent, prosternal process faintly bordered 

 at apex, with a few setas. Upper surface of tarsi glabrous ; 

 first three joints of front tarsi ( £ ) rather longer than wide. 



The species belongs to the C. chalcothorax, Wied., group, 

 and seems most nearly allied to C. privates, Bates, of which 

 I have seen no example. The last-named species comes from 

 Burma and is a much larger insect ; it differs also to some 

 extent in colour and has the head coarsely punctate. The 

 coloration of the elytra in C. tudicus (except for the reddish 

 border) is as in C. chalcothorax, but the prothorax is more
