tlie point bifid and purple ; the basal part is keeled in the 

 middle. Mandibles purplish black. Pronotum broader than 

 long, roundly convex above, coarsely and closely punctured. 

 The sides of the mesonotum strongly but not closely 

 punctured ; the base with the punctures more widely sepa- 

 rated ; the apex smooth. Scutellura smooth and marke 1 all 

 over with widely-separated punctures ; the postscutellum 

 closely and finely punctured, its central part with large deep 

 punctures. There are only two central keels in the middle 

 of the median segment ; they form almost a triangle, the 

 space enclosed by them is obliquely striated on either side at 

 the base ; the apex transversely striated ; the rest is more 

 finely transversely striated ; the keel bordering the apex in 

 the middle is slightly dilated ; the middle of the dih\tation 

 transverse, its sides oblique ; the apex of the segment above 

 reticulated ; the keels on the lower part not forming distinct 

 areae, being widely waved. The part of the propleurai above 

 the keel has large scattered punctures all over ; the lower 

 part has a few punctures on the base ; the apex on the lower 

 side has some stout, oblique, irregular keels. Mesopleura 

 with large, deep, distinctly separated punctures ; mctapleurse 

 reticulated in the middle, at the base and apex are a few 

 curved irregular keels. The coxte are green ; the four 

 posterior femora rufous, the anterior black, blue behind ; 

 the tibiaj on the inner side dull rufous ; the pad on the pen- 

 ultimate tarsal joint does not reach to the middle of the ne.xt 

 joint ; the claws are bifid, the joints of almost equal length. 

 The first transverse cubital nervure is obliterated entirely ; 

 the second is interstitial, with the apex of the nervure 

 bounding the apex of the radial cellule ; the first recurrent 

 nervure is received in the middle, the second in front of the 

 basal third of the cellule. Abdomen shorter than the thorax y 

 above bright purplish blue ; the apical segment dark green ; 

 the narrowed part of the petiole is not quite so long as the 

 dilated apex and is black in colour ; the apex of the petiole 

 and the second segment sparsely punctured, the punctures 

 small and shallow, longer and deeper on the apex of the 

 second segment ; the second segment is longer than usual, 

 more than twice longer than broad ; the third segment is 

 deeply and largely punctured, the base in the middle smooth ; 

 the apex keeled in the middle ; the apex all round has a 

 sharply raised border ; above there are only three segments 

 distinguishable, below only two.
