 " $ . Head and thorax coarsely, abdomen finely punctured ; 



head and thorax very slightly narrower than abdomen ; clypeus 

 emarginate anteriorly; a well-defined sinuate transverse ridge below 

 anterior ocellus, and the front below it concave, with sparse white 

 pubescence, under which it is finely punctured; head viewed from 

 above nearly twice the size of the pronotum, the latter with a 

 median longitudinal depression ; 1st abdominal segment almost 

 impunctate in the centre, 2nd segment with a median longitudinal 

 carina, 3rd segment sexdentate, the teeth sharp and with a sub- 

 apical row of foveae. Dark blue-green, with a purple tint in some 

 lights ; the clypeus, mandibles at base and scape of the antennae 

 bright metallic green ; mandibles black in the centre, red at apex ; 

 2nd abdominal segment green at apex ; antennae and tarsi dark 

 red, almost black ; wings hyaline, tegulse purple, radial cell not 

 quite closed.

$ . Dark green, the middle of the scutellum, the disc broadly 

 of the 2nd abdominal segment and the apical area of the 3rd seg- 

 ment dark blue, the space round the ocelli and the anterior portion 

 of the median area on the mesonotum black, facial cavity and 

 clypeus bright golden or bronzy green ; antennae brown, the scape 

 in front and basal joint of flagellum above green. In some specimens 

 the base of the 3rd abdominal segment is dark blue, in others the 

 black on the vertex and on the median area of the mesonotum is 

 entirely wanting. Head and thorax densely punctured, the punc- 

 tures serried and close together (except on the scutellum and 

 postscutellum, where they are wider apart), and themselves with 

 finer punctures within ; abdomen with large scattered punctures 

 which, like those on the thorax, are finely punctured within, the 

 intervening spaces very densely and minutely punctured, the whole 

 abdomen having thereby a densely rugulose, finely reticulated 

 appearance ; facial cavity finely punctate-reticulate, the upper 

 third or fourth with large and coarse punctures ; pilosity short, 

 very sparse, brownish in colour, the facial cavity with a little very 

 fine silvery pubescence. Head thick, as broad as the pronotum 

 anteriorly ; occiput slightly emarginate, vertex and front convex. 

 sloping to the front ; facial hollow shallow above, margined by a 

 transverse carina ; antennae slender, somewhat elongate, 2nd joint 

 of the flagellum longer than the 3rd. Thorax: the pronotum 

 short, transverse, subcylindrical, the propleurae excavate ; meso- 

 notutn and scutellum gently convex ; mesopleurae rugose, longi- 

 tudinally grooved, the apex beneath subacute ; postscutellum convex, 

 rounded ; posterior lateral angles of the median segment broad at 

 base, acute at apex but short; wings hyaline, nervures brown,
