cate like a funnel at the end. The disk rugoso-punctate, margined 

 on sides and prolonged so as to form with above cup a blunt spine 

 On outer edge of each pit the axilla forms a prominent tooth which 

 reaches a little beyond middle of scutellum. Propodeum somewhat 

 prolonged into a neck, the carinae converging in front. Mesopleura 

 separated from sternum by distinct carina with a finer ridge just 

 above it. Metapleura pubscent with bare spot above. Wings dusky, 

 reaching beyond abdomen, radial cell closed, three times as long as 

 broad, cell to wing ratio 1:3.8, first abscissa of radius shorter .than 

 second, no areolet, surface pubescent, margin ciliate. Abdomen 

 longer than broad, normally compressed, obliquely truncate behind, 

 second tergite occupying 0.7 and with ring of hairs at base.

Genotype. — Zaeucoila unicarinata Ashmead. Monobasic. 



Short, robust. Head not broader than thorax, cheeks margined, 

 antennae in male with first segment of flagellum slightly longer 

 than second, all flagellar segments oblong-oval, twice as long as 

 broad (not "about thrice" as stated by Ashmead Math "first joint of 

 flagellum not longer than second"). Pronotum truncate. Mesoscu- 

 tum shorter than broad, polished, with a low median ridge which is 

 widest in front and tapers gradually to a point at or near hind margin, 

 short grooves just over fore wings. Scutellum rounded behind, 

 cup large, almost circular, over half as wide as disk, reaching nearly 

 as far back as disk, pits at base large and deep, disk rugose. 

 Mesopleura separated from sternum by carina. Radial cell short, 

 closed, wing surface pubescent and margin ciliate. Abdomen with 

 ring of hairs at base. 



Separated from Moneucoela Dalla Torre and Kieffer, Frireniella 

 Kieffer, and Rhabdeucoela Kieffer, which all have a median longitudi- 

 nal ridge on mesoscutum, by the short and dosed radial cell.
