the sternum, the prepcctus, however, tineli' rugose ; propodeum rugosely 

 punctate becoming coarsely rugose dorsad, the petiolar region smooth, 

 shining and limited above by transverse cariniform rugosities; the meta- 

 pleura finely rugoso-punctate. Mesonotum with a much finer, shorter 

 pubescence than on the face ; that on the mesopleura a little longer than 

 on the scutum and that on the propodeum as long and dense as on the 

 face. 



Abdomen about a third longer than the head and thorax; basal tergite 

 slightly longer than its apical width, its basal half flattened, not or 

 hardly excavated medianly, forming an obtuse angle with the apical, 

 transverse part; the following tergites transverse, the second longest, the 

 rest gradually shortening, the third and fourth widest ; the second to 

 fourth wtih a slight transverse impression on each side half way between 

 the middle and apex, a longitudinal furrow on each side close to the 

 lateral margin and a somewhat oblique furrow on either side on basal 

 half just within the spiracles, the intervening area between these sulci 

 forming a spiracular protuberance, which is smooth and shining with 

 the spiracle located at its apical end, and forming a distinct although 

 small emargination on the sides of the second and third tergites in dor- 

 sal aspect ; apical margin of the first five tergites slightly elevated and 

 impunctate, the basal half of the first, the basal margin of the second 

 together with the three apical tergites also impunctate, smooth and 

 shining, with a delicate reticulate surface sculpture except at base of 

 first two segments ; apical half of the first and the four following ter- 

 gites otherwise densely, moderately coarsely punctate with round punc- 

 tures, and hardly at all tuberculate either before or behind the transverse 

 impression; the last tergite with two fine impressed lines 'meeting in an 

 acute angle at the middle of the basal margin, the enclosed triangular 

 area having the surface sculpture finer and smoother; pubescence rather 

 conspicuous on the venter and wide epipleura, on the sides of 

 the apical tergites and on the apical margin of the eighth tergite; the 

 basal and middle tergites with an extrefnely fine or microscopic pubes- 

 cence; ovipositor about one-half as long as the abdomen, its sheaths 

 finely, densely pubescent. 



Legs of the usual type, the front tibiae dorsally thickened at the 

 middle and then somewhat rapidly constricted towards the apex ; last 

 joint of the tarsi about thrice as long as the fourth; the claws simple 

 although greatly widened at base. Areolet of wings sessile, quadrangu- 

 lar, the transverse vein emitted beyond its middle ; the discocubital vein 

 slightly arcuate, usually not broken ; apical abscissa of radius straight ; 

 nervulus a little postfurcal or sometimes interstitial ; nervellus of hind 

 wings broken somewhat more than half way above its middle. , 



Length : About 5 to 10 mm., smaller specimens being most abundant. 

 $ . — Similar to female, the antennae rarely brown, usually entirely 

 fuscous or blackish; the hind tibiae and tarsi black, with the tibial spurs 

 and a band from the middle half way to the base of the tibiae pale yel- 

 lowish or white; the middle tibiae with a similar pattern, but the dark
