and the front tibiae reddish brown, tibial spurs and the ovipositor 

 reddish testaceous, the ovipositor sheaths black; wings subhyaline, 

 faintly tinged with fuscous, the stigma and costal vein black, other 

 venation dark brown. Head a little narrower than the thorax at 

 the tegulae, the occiput concave, vertex punctate near ocelli, nearly 

 smooth laterally and behind and sloping strongly from the posterior 

 ocelli to the occipital carina, which is slightly interrupted above; 

 frons depressed, punctate laterally, smooth medially with a slight 

 median ridge; posterior orbits prominent, almost as broad as the 

 width of the eye, not at all receding, and nearly smooth, except for 

 fine punctures along the occipital margin; ocellocular line slightly 

 less than the postocellar line and equal to about one and one-half 

 times the greatest diameter of a lateral ocellus; face convex below 

 the antennae, moderately punctured, the width between the eyes at 

 antennae a little greater than the distance from the anterior margin 

 of the antennal fossae to the base of clypeus; malar space rather 

 long; cheeks broad and finely closely punctate; antennae 32-jointed in 

 the type, the first flagellar joint three times as long as broad, 10 or 

 12 apical joints quadrate; mesoscutum and scutellum shining, mod- 

 erately hairy with weak punctures, the parapsidal grooves 'foveolate 

 their entire length; propleura strongly rugulose-punctate, smoother 

 along the dorsal margin; mesopleura smooth with the sternauli 

 foveolate; propodeum without carinae, mostly rugulose-punctate, 

 with the base before the spiracles more or less smooth and polished 

 and with an apical depression each side of the middle, which is mostly 

 smooth; sides of propodeum sparsely punctured, except along the 

 apical margin, which is strongly punctured; hind coxae sparsely 

 sculptured ; longest hind tibial spur over half the length of first tarsal 

 joint; intercubitus and second abscissa of radius forming a nearly 

 straight line, stub of cubitus beyond the intercubitus slightly longer 

 than the second abscissa of cubitus; abdomen slightly longer and 

 a little narrower than the thorax, the first tergite entirely and the 

 second for the most part finely rugulose-punctate, the base, apex, and 

 lateral margins of the second narrowly smooth; tergites beyond the 

 second polished ; ovipositor about 4 mm, 



Male. — Is like the female except that apical antennal joints are not 

 quadrate but longer than broad, the base of the flagellum is black 

 like the remainder, and the second tergite is almost sculptureless.
