median segment posteriorly with a very short lateral spine, or, 

 strictly speaking, an obtuse protuberance ; legs with the penulti- 

 mate joint of the tarsus enveloping on all sides the basal half of the 

 apical joint ; the intermediate and posterior tarsi punctured ; cla^\'s 

 bitid. Abdomen v^ith the dorsal plate of the 2nd segment about 

 1^ times as long as it is broad. Metallic blue or green, sometimes 

 slightly bronzy ; the antennae and tarsi black, the posterior femora

5 . Head and thorax punctured, the punctures large and coarse, 

 very sparse on the mesonotum, scutellum, postscutellum, and 

 sides of the thorax ; the clypeal carina prominent, bifurcating close 

 to the apex ; eyes small, separated above by the length of the basal 

 four joints of the flagellum of the antennae ; the 3rd, 4th, and 5th 

 joints of the latter subequal ; the raised portion of the pronotum 

 very convex, transverse, much broader than long, divided medially 

 by an impressed line ; median segment with four carinse, the 

 inmost two convergent, roughly forming a triangle with the base, 

 the next two rather close together, the outer ending in a blunt 

 tubei'cle just below the upper posterior angle of the truncated 

 apex of the segment, the spaces between the larger longitudinal 

 carinae with raised transverse striae somewhat close together ; legs 

 stout, the posterior tibiae with a few coarse punctures, the 2nd 

 and 3rd joints of the tarsi sagittate, the subapical joint about half 

 the length of the apical and overlapping it on the underside ; 

 abdomen strongly compressed, the apical four segments quite flat, 

 vertical, the 2nd strongly produced below at right angles to the 

 1st, above not quite so broad as long. Dark shining bluish green ; 

 the central plate of the mesonotum, the apical abdominal segment 

 above, and the apical three below brownish, the anterior tibiae 

 and basal joint of the tarsi and the posterior four femora deep 

 red : wings hyaline, infuscated on the disc of the fore wing, the 

 latter with an appendiculate radial and two cubital cells; the 1st 

 cubital cell twice the length of the 2nd, receiving the 1st recurrent 

 nervure very little after its middle, the 3rd cubital cell reaching 

 beyond the radial and receiving the 2nd recurrent nervure ; the 

 2nd transverse cubital nervure received at the apex of the radial 

 cell.
