as tibiae and inner calcariiim fully half as long as basitarsus; simple 

 claws; strongly curved apical abscissa of radius; large obliquely 

 rhomboidal areolet; very strongly curved or subangulate second 

 recurrent; rather long second discoidal cell; smooth, pohshed, apically 

 compressed abdomen with first tergite at least twice as long as broad 

 at apex; ovipositor short, straight, ^yit\l sheath not or barely half as 

 long as first tergite; entirely black body, this color including at least 

 the coxae and trochanters and sometimes the entire legs; and more or 

 less distinctl}' infumate wings. 



The present species is distinct from all the others in its bright yellow, 

 apically infumate wings. 



Female. — Length 15 mm, antennae 13 mm. 



Head slightly more than twice as broad as thick; occiput rather 

 deeply concave; temples weakly convex, sharply receding, finely 

 sparsely punctate; frons densely punctate, mat, Math a median welt 

 between antennal foramina; face densely and medially confluently 

 punctate, medially longitudinally elevated and with a deep impression 

 on each side below antenna, distinctly less than twice as broad as 

 long; clypeus more than three-fourths as long as broad, divided 

 slightly before middle, weakly by elevation and distinctly by sculp- 

 ture, apical margin sharply rounded; cheeks in front view slightly 

 concave, their extended angle sharply acute; malar space three-foiu-ths 

 basal width of mandible; mandible twice as long as broad at base, 

 little narrowed toward apex; eyes slightly longer than dorsal width 

 of face, distinctly convergent; antenna 58- to 60-jointed, slightly 

 attenuate at apex, first joint of flagellum barely twice as long as 

 second, joints just beyond middle about as thick as long. 



Thorax densely punctate, least densely so and strongly shining on 

 mesopleiu-um and scutellum ; notauli shallow but distinct ; propodeum 

 finely reticulate rugose, with more or less distinct lateral median traces 

 of apical carina, and with lateral and pleural carinae indicated; 

 spiracles elongate, situated well above pleural carinae. 



Legs rather stout, hind femur barely six times as long as thick, 

 three-fourths as long as tibia; inner hind calcarium distinctly more 

 than half as long as basitarsus, apical joint of hind tarsus nearly as 

 long as third joint. 



Wings: Apical abscissa of radius a half longer than basal abscissa, 

 strongly curved at base; areolet obhque rhomboidal, apical angle 

 acute, second recurrent shghtly before middle; basal abscissa of 

 subdiscoideus hardly a half longer than second recurrent, the latter 

 strongly curved above; nervulus slightly postf ureal; abscissula twice 

 as long as intercubitella. 



Abdomen polished, with only sides of petiole punctate, compressed 

 at apex; first tergite twice as long as broad at apex, second longer 

 than broad at base; ovipositor sheath less than half as long as first 

 tergite.
