thorax sloping abruptly, almost smooth, with a distinct longitudinal carina on

 gradually beyond the middle to a fine point, ridged dorsally from basal margin 

 of 2d segment to apical margin of 4th, some deep punctures at base of 3d and 

 4th segments and a transverse row of broad shallow costae anteriorly on 2d, 3d, 

 4th and 5th segments, each with a fringe of long procumbent hairs posteriorly. 

 Sheath of ovipositor broad and flat, slightly protruding. Legs stout and hairy, 

 hind coxse greatly developed. 



Metallic green with some purplish reflections, head and thorax bluish green, 

 hind trochanters, knees, tips of tibiae and tarsi reddish to yellowish, antennae

 E. incerta, new species. 



Female. — Length 4.5 mm., expanse of wings 7.25 mm., greatest width of 

 fore-wing 1.35 mm. Head and thorax closely umbilicately punctate, rather 

 thickly clothed with a silvery white pubescence, prothorax laterally, hind coxae 

 outwardly and mesopleura above shagreened, the latter aciculate below, abdomen 

 smooth and shining, segments i, 2, 3, 4 basally, 5, 6, 7 entirely microscopically 

 punctate and sparsely clothed with silvery hairs. Head transverse, front wide 

 between the eyes, which are small, face also broad, ocelli arranged in an obtuse 

 triangle, antennae inserted on middle of face, 9-jointed (i ring-joint and an 

 undivided club), joint measurements in mm. i .33, 2 .12, 4 .iS, 5, 6 and 8 .13, 

 7 .12, 9 .32. Thorax convex, almost tuberculate, pronotum as long as mesonotum, 

 parapsidal grooves distinct, scutellum convex, rounded posteriorly, metathorax 

 sloping abruptly, depressed in the middle. Abdomen compressed, elongate ellip- 

 tical from above, triangular from side, apically produced to a fine point, 4th 

 segment widest, wider than 2 and 3 together, sheaths of the ovipositor broad, 

 slightly protruding. Legs pubescent, hind coxae enlarged. 



Black, mandibles, base of scape outwardly, tip of ovipositor sheaths and 

 legs (with the exception of the femora and tibiae outwardly) brown (only base 

 and apex of hind femora and tibiae brown). Wings hyaline, marginal vein short, 

 postmarginal vein nearly as long, but stigmal shorter, ending in a club. 



Male. — Length 3.75 mm. Like the female but the funicular joints of 

 antennas nodose, pedicellate at apex, each node with two whorls of long hairs. 

 Club not quite as long as scape but longer than funicle joints, which are all sub- 

 equal, pedicel very small and obconic. Abdomen long petioled, much reduced 

 in size and rather hatchet-shaped. Petiole broad and flat and shagreened.
