notum with punctate parapsidal furrows, which converge before 

 reaching the scutellar fovea ; scutelhim strongly convex at the base, 

 with a large depression which is rugulose and indistinctly divided by 

 a raised median line. Metanotum rug-ose, indistinctly areolate ; 

 medially at the base with a short carina which bifurcates to form two 

 carina 3 extending to the posterior angles ; several other irregular and 

 indistinct carina? present. Pro- and mesopleura? smooth, the former with 

 a longitudinal depression which has a series of small fovea? along its 

 base, and with a few shoi't grooved lines posteriorly. Mesopleura 

 behind with a row of large punctures and a small fovea in the middle 

 near the posterior margin. Abdomen nearly as long as the thorax, 

 first segment with a strongly elevated carina arising at each anterior 

 angle, converging and becoming less prominent behind ; irregularly 

 longitudinally striated but less conspicuously so along the median con- 

 cavity between the discal cari^e. following segments polished, smooth ; 

 second and third segments equal, together one-half longer than the 

 first; fourth, fifth and sixth growing shorter, others, still shorter. 

 Ovipositor as long as the abdomen, its sheaths black, hairy. Legs rather 

 stout, honey yellow or pale fulvous, including the coxa? ; the hind tibia? 

 with a piceous stripe above, win^s hyaline ; veins and stigma piceous ; 

 the latter broad, as wide as the transverse cubitus ; radial cell pointed, 

 one-third longer than the stigma ; first section of radius one-half as 

 long as the transverse cubitus ; discoidal cell sessile above, the recurrent 

 nervure received at a distance before the tip of the first cubital cell 

 equal to the length of the first section of the cubitus ; submedian cell 

 slightly longer than the median ; second discoidal cell closed at its 

 lower apical angle ; anal cell with two short stumps of veins above.
