$ . Head, thorax, the base and apical margin of the 1st, the 

 apical margin of the 2nd and the 3rd abdominal segment on the 

 sides metallic green ; the region of the ocelli, two spots on the 

 ^ pronotum, the medial area of the mesonotum, the middle of the 

 ' disc of the 1st, and the greater portion of the base broadly of 

 the 2nd and 3rd abdominal segments brilliant metallic blue ; an- 

 tennae dusky black, the scape above metallic blue, the basal two 

 joints of the flagellum above green, legs green on the outside, on 

 the inner side together with the tarsi dusky brownish black ; head, 

 thorax and abdomen densely punctured, the punctures on the 

 abdomen except at base somewhat finer and shallower than on 

 the head and thorax, on the back of the thorax and median seg- 

 ment they are cribrate; pilosity whitish, long, abundant and 

 slightly oblique on the head beneath, on the legs and on apex of 

 the abdomen, entirely absent on the 1st and 2nd abdominal seg- 

 ments above. Head subglobose, eyes large ; clypeus vertical 

 very narrow anteriorly, at the bases of the mandibles with a 

 coppery sheen ; antennal hollow broad, within finely punctured ; 

 front with a transverse carina bent downwards at each end, 

 giving off from the middle a broad loop, medially on which above 

 is placed the anterior ocellus ; occipital margin transverse, slightly 

 broader than the pronotum ; antennae rather short and thick, the 

 2nd joint of the flagellum the longest. Thorax: the pronotum 

 short, very convex, transversely rectangular, the sides widely but 

 slightly emarginate, the posterior lateral angles a little produced ; 

 propleurae excavate, the hollow finely rugulose svithin ; mesonotum 

 convex, medial area rectangular, somewhat narrow, about twice as 

 long as broad, mesopleurae coarsely punctured, angular beneath, 

 with a well-marked oblique carina from beneath the base of the 

 wings circling round the produced angular apex beneath ; scu- 

 tellum from above semicircular ; postscutellum crescentic, slightly 

 gibbous, completely hiding the median segment except its produced 

 acute posterior lateral angles ; wings hyaline with a brownish tint, 

 nervures and tegulae dark brown ; legs slender. Abdomen some- 

 what long and comparatively massive, medially cariuate from near 

 the base to apex, the base with three well-marked impressions ; 

 3rd segment nearly as long as the 2nd, with an anteapical series of 

 10 moderately large, round, foveate punctures, the apical margin 

 gently rounded with two acute teeth close together in the middle ; 

 ventral segments green, smooth and shining, with the base of the 

 2nd and sides broadly of the 1st segment brownish black. 

 c? unknown. 



Length, $ 8 ; exp. 16 mm. 



Hob. I procured one specimen of this distinct species at Tavoy 

 in Southern Tenasseriin. Superficially it resembles C. angustata. 

 Mocs., but the bidentate apical margin of the abdomen distinguishes 

 it at once.
