ART. 14 ICHNEUMOlSr-PLIES OF GENUS POLYCYRTUS CUSHMAN 17 



space distinctly shorter than basal width of mandible, not distinctly 

 constricted, mouth as broad as narrowest width of face; temples 

 flat; diameter of ocellus two-thirds as long as ocell-ocular line; basal 

 joint of flagellum about eight times as long as thick. Prescutum 

 low; prepectal furrow distinctly foveoiate; metapleurum more dis- 

 tinctly punctate, rugose posteriorly; propodeal carina subangulate 

 medially, apophyses short, obtuse, about midway between carina 

 and apex; hind femur thick, about twice as thick in middle as at 

 apex; areolet broad, recurrent antef ureal; nervellus broken above 

 basal third. 



Clypeus white, palpi entirely white; annulus beginning at base 

 of fourth joint of flagellum ; pleura and sternum distinctly paler than 

 dorsum; tegulae and scutellar carinae stramineous; tergites not 

 definitely white margined apically. 



Tyfe locality. — Cavinas, Beni, Bolivia.

14. POLYCYRTUS (POLYCYRTUS) PROMINENS, new species 



FeTTwle. — Length 14 mm. 



Differs from the foregoing description of nigriclypeatus as fol- 

 lows : Frontal horn more slender, nearly cylindrical, rounded at 

 apex; face faintly alutaceous, malar space much shorter than basal 

 width of mandible, hardly constricted, mouth fullj^ as broad as nar- 

 rowest wielth of face; basal joint of flagellum eight times as long as 

 thick. Anterior lateral angles of pronotum very prominent, the ca- 

 rina high; prescutum low, prepectal furrow distinctly foveoiate; 

 metapleurum rugoso-punctate in middle; propodeum less deeply 

 impressed, the basal elevations not so high, carina more strongly 

 curved medially, apophyses shorter, straight, compressed, fully as 

 close to apex as to carina ; hind femur nearly twice as thick in middle 

 as at apex; inner calcarium two-fifths as long as basitarsus; areolet 

 rather broad, recurrent antef ureal; nervulus postf ureal, post-nervu- 

 lus broken slightly above middle, nervellus above basal fourth: sec- 

 ond tergite little more than three times as long as broad at base, 

 considerably shorter than first; sheath distinctly shorter than hind 

 tibia. 



Face and clypeus as well as mouthparts white; pleura and ster- 

 num paler than dorsum; wings more yellowish; apical white bands 

 of tergites of nearly uniform width. 



Type locality. — Rurrenabaque, Rio Beni, Bolivia.
