" S . The clypeus cariuate, somewhat compressed. Head punc- 

 tured, no carina on the front above, but above each antenna a short 

 carina. Prothorax slender, strongly compressed, finely trans- 

 versely striate, and divided by a longitudinal groove, not tuberculate 

 posteriorly, but shining ; the prosternum punctured. The meso- 

 thorax coarsely, the mesonotum still more coarsely punctured, the 

 fovea on this short, deep, nearly orbicular. Median segment 

 slender, the apex bidentate, not acutely truncate, above with 

 transverse raised striae, the raised longitudinal striae complete. 

 The medial carina at apex almost obtusely bifurcate ; of the lateral 

 carinae, the 1st pair sinuate, at the base convex, then concave, 

 lastly parallel, the 3rd pair convergent towards the apex, and 

 continuous there with the arch of the medial one, 2nd pair free at 

 base at their origin, at apex joined on to the arch of the 3rd pair ; 

 the lateral tubercles or teeth projecting sideways ; the posterior 

 face of the segment subconvex like the sides, coarsely reticulate. 

 Abdomen highly polished, impunctate. Metallic blue ; antennae 

 and the tarsi black ; posterior femora red, with the apex blackish 

 blue ; wings hyaline, nervures fuscous.

5 . Front, vertex, and cheeks smooth, with scattered punctures ; 

 front and vertex broad ; eyes very slightly convergent towards the 

 vertex ; antennae remarkably stout, the joints of the flagellum 

 constricted at their bases, length of 2nd joint not quite 2g times 

 its breadth at the apex ; a short very slight carina over the base 

 of each antenna ; the medial carina of the clypeus bifurcating at 

 its apical third, and forming at the margin two more small but 

 distinct teeth; a middle tooth consequently absent; pronotum 

 not raised into a tubercle, nearly cubical, above almost flat, with a 

 median longitudinal deeply impressed line, and as well as the 

 mesonotum coarsely but not thickly punctured, a stiff hair springing 

 from each puncture ; mesopleurae with coarse scattered punctures ;
