$. Dark bluish green, the discs of the 2nd and 3rd abdominal 

 segments broadly violet-blue ; in certain lights the whole of these 

 two segments appear of that colour ; the antennae black, the scape 

 and basal two joints of the flagellum green ; legs and the basal 

 joint of the tarsi of the posterior legs green ; head and thorax 

 densely and very coarsely punctured, rugose, 1st abdominal seg- 

 ment as coarsely but more sparsely punctured, not rugose, the 

 remainder of the abdomen more finely punctured, the apical 

 margin of the 3rd segment smooth, unpunctured, shining, slightly 

 ohitinous and translucent at base ; facial cavity, around the base 

 of the antennae and on the clypeus entirely smooth and shining, 

 above closely and somewhat finely punctured, pubescent, the hairs 

 long, slightly hiding the sculpture ; pilosity tolerably abundant, 

 brownish. Head thick and broad above, as broad as the pronotum, 

 from in front triangular, the cheeks strongly convergent anteriorly ; 

 clypeus raised in the middle, the anterior margin medially deeply 

 emarginate ; the facial cavity deep, margined 

 above by a transverse carina, from which are 

 emitted two curved carinae meeting above, 

 behind the anterior ocellus ; antennae stout, 

 pubescent, the 2nd joint of the flagellum a 

 little longer than the 3rd ; front and vertex 

 broad, convex ; occiput sharply transverse. 

 Thorax : the pronotum subcylindrical, decli- 

 vous anteriorly, rounded and convex poste- 

 riorly, the sides slightly convergent towards

smooth within ; mesonotum, scutellum and 

 postscutellum convex, the mesonotum long 

 and ample, the scutellum rather short, transversely rectangular ; 

 mesopleurae broad, rather short, very coarsely deeply punctured, 

 rugose, with a medial broad line of large foveae from under the 

 base of the wing almost to the apex, this latter broad and 

 obtuse ; postscutellum very rough and coarsely sculptured, tri- 

 angular and prominent, the apex obtuse, posteriorly entirely 

 overhanging the median segment, of which the posterior lateral 

 angles are very broadly produced and very acute at apex ; 

 wings fusco-hyaline, nervures brown, tegulae purple ; legs short 

 though slender. Abdomen broad, massive, truncate or transverse 

 at base, with a somewhat deep impression on each side and 

 a shallower medial one ; 2nd segment medially longitudinally 

 carinate along its apical half, the basal area of 3rd segment convex, 

 not carinate ; anteapical series of fdveae large, the fovese opening 

 downwards ; anal area medially strongly carinate, the carina ter- 

 minating in a strong acute tooth, the sides slightly convergent 

 posteriorly, the apical margin transversely truncate, armed at the
