 Wings hyaline, the veins light brown. Head transverse, the vertex broad, the 

 cheeks rather broad, rounded ; eyes oval, pubescent; antennae inserted below the 

 middle of the face, incrassated. the pedi(^el much longer than any of the funicular 

 joints, the latter transverse, increasing in width to club. Thorax subovoid, the 

 upper anterior margin of the pronotum with a slight reflexed margin ; mesonotura 

 across the shoulders nearly twice as wide as long, a little narrowed anteriorly, 

 the parapsidal furrows shaqily indicated anteriorly for half its length or a little 

 more ; the extreme tip of scutellum and the postscutellum smooth, impunctured ; 

 metathorax produced into a small, subglobose neck, with a median carina and 

 lateral folds, the median carina forked at apex and extending on each side of the 

 neck intersecting with the apices of the lateral folds, the surface between the 

 folds and the median carina as well as on each side of them, finely rugulose ; the 

 spiracles oval, away from the postscutellar ridge ; the superior margins of meta- 

 pleura fimbriate. Wings hyaline, the marginal vein less than twice as long as 

 the stigmal, the postm.irginal vein only a little longer than the stigmal. Abdo-

 slight median sinus; antennse subdavate, slender, the pedicel scarcely as long as 

 the first joint of funicle, the funicular joints very gradually shortening and 

 almost imperceptibly thickening toward the club, the first being about twice as 

 long as thick, the last scarcely longer than wide. Thorax with the mesonotal 

 furrows only indicated anteriorly, the pronotum exceedingly short, appearing 

 above as a sharp, transverse line; metathorax short, scarcely half the length of 

 the scutellum. tricarinate, the neck or produced ajjcx of metathorax short, the 

 median carina forked at and surrounding its base, the lateral folds strongly curved, 

 the spiracles prominent, linear-elliptic, two and a half times as long as wide. 

 Wings hyaline, the veins brownish, the marginal vein about two and three-fourths 

 times as long as the stigmal, the })ostmarginal a little longer than the stigmal. 

 Abdomen conic-ovate, nearly one-half longer than the head and thorax united, 

 the second segment (first body segment) the longest, the third the shortest, the 

 segments from the third impercejjtibly increasing in length, none being very
