joint ; club 5-jointed, the first joint rounded, considerably smaller 

 than the other joints, 2-4 subequal, a little longer than thick, the last 

 ovate, a little longer than the preceding and slightly more than twice 

 as long as thick ; all club-joints fluted. Mesouotum fully twice as 

 long as wide at base ; collar striated at sides ; scutellum indistinctly or 

 feebly striated at sides ; the cup small, ovate, with the disk smooth, 

 impunctate. Wings hyaline, entire and rounded at apex, ciliated ; 

 the veins (except the basal nerve, stigma, and marginal vein, which 

 are piceous) reddish yellow ; the marginal vein is open along the fore 

 margiu, while the first and second abscissas of radius are about 

 equal in length, the marginal cell being a little more than twice as 

 long as wide. Abdomen not quite so long as the head and thorax 

 united, with a slight rim at base but without pubescence, and, 

 except some striae at base above, perfectly smooth and polished.

2 . Length 1 mm. PoUshed black ; antennae rufo-piceous, the 

 club black ; legs honey-yellow, the coxse and clavate parts of femora 

 browTi or rufo-piceous : mandibles reddish yellow. 



Antennse 13-jointed, about as long as the head and thorax united ; 

 the scape clavate, 3 times as long as thick ; funicle 6-jointed, the 

 first joint 3 times as long as thick, the second hardly longer than 

 thick, joints 3 to 6 moniliform, equal in size ; club 5-jointed, the 

 first rounded and much smaller than the second, the second 

 smaller than the thu'd but a little longer than thick, joints 3-4 

 subequal, oblong, the fifth ovate, hardly twice as long as thick. 

 Mesonotum not twice "as long as wide at base, the scutellum dis- 

 tinctly striated at sides ; the cup small, elliptic, with a small fovea 

 posteriorly and a single puncture on the anterior part. Wings 

 hyaline, ciliate, the apex of front pair with a slight sinus ; other- 

 wise the venation is similar to P. coxalis, except that the second 

 abscissa of radius is evidently slightly longer than the first. 

 Abdomen as long as the head and thorax united, without a 

 pubescent girdle at base. 



Balthazar. Described from one female specimen. 



Eeadily distinguished from the preceding species by the shorter 

 antennae and the relative length of same, shorter mesonotum, and 

 the shape of the anterior wings.
