New chalcidoid from Paraguay. 403 



Body from dorsal aspect shaped as in the species microgaster 

 Ashmead; ocelli nearly in an equilateral triangle, the lateral ones 

 tlieir own width distant from the eye margin, the Vertex long. 

 Parapsidal furrows as in microgaster Ashmead but somewhat longer, 

 distinct, but not complete, running two-thirds the length of the 

 mesonotum. Scutellum with a midlongitudinal grooved line and a long 

 fovea bearing a long seta at the caudo-lateral corner; no lateral 

 grooved or pimctured line. Metathoracic spiracle round, small; 

 metathorax with a smooth median carina as in microgaster, bordered 

 on each side with a sulcus but the carina is at least subacute, the 

 sulci not roughened, bordered laterally by a carina or an acute 

 margin. Abdomen conic-ovate, convexed ventrad, above slightly 

 convexed, about equal to the thorax in length, its petiole short, not 

 conspicuous, its second segment long, occupying slightly over half 

 of the surface, the remaining segments all short, their incisions wide 

 and dark, each segment bearing a transverse row of greyish hairs. 

 Ovipositor not exserted. 



Body polygonally reticulated, the large second segment of the 

 abdomen and the metanotum smooth, polished; Vertex with some 

 small punctures, present but much more scattered on the thoracic 

 dorsum, also; these minute punctures are setigerous. Eyes with 

 moderately dense minute greyish pubescence which is short and erect. 



Fore wings hyaline, the marginal vein over twice the length 

 of the submarginal vein, straight, long and slender, the postmarginal 

 and stigmal veins very short, mere spurs. Discal ciliation uniform 

 and dense, Mie marginal cilia short. Posterior wings similarly ciliated 

 discally. Legs normal, tarsi 4-jointed. 



Antennae 8-jointed: scape, pedicel, 1 minute ring-joint, 3 funicle 

 joints and 2 club joints ; submoniliform, cylindrical. Scape cylindrical, 

 longer than the pedicel and the flrst funicle Joint combined; pedicel 

 obconic, shorter than the first funicle Joint; the latter cylindrical 

 oväte, a fourth longer, the second Joint of funicle cylindrical, slightly 

 shorter and narrower, the third oval, still somewhat shorter, the 

 proximal club Joint a little longer and broader, the terminal Joint 

 dome-shaped, smaller than the pedicel, terminating in a short stout 

 spur (considered erroneously by many a third club Joint). Antennae 

 clothed with stiff white setae from whitish setigerous tubercles which 

 are minute.
