New chalcidoid from Paraguay. 405 



mesonotum included by them, straight; mesoscutum without a median 

 grooved line, longer than the scutellum; tlie latter witli a straight 

 longitudinal groove on each side of the median line, otherwise simple, 

 peltate, with a more or less obscure, round fovea laterad of each 

 grooved line about two-thirds down toward the apex. Metanotum 

 with a distinct, complete median carina whicli at the caudal margin 

 divides and runs laterad aroimd that margin; also a lateral carina 

 mesad of the spiracle and a more obscure confused one laterad of 

 it; metathoracic spiracle round, moderately large, near the cephalic 

 margin. Metathorax with a slight, collar-like neck. Abdomen sessile, 

 with no trace of a petiole, pointed conic-ovate, longer than the head 

 and thorax combined, its apex acute and acuminate, the ovipositor 

 not exserted, the segments not distinct, convexed ventrad near base, 

 concaved dorsad, none of the segments very long. 



Fore wings hyaline but with a dusky appearance from the 

 discal ciliation which is moderately dense and uniform, absent 

 proximad of the proximal fourth of the marginal vein with the 

 exception of a broken oblique line running from the break of the 

 submarginal vein and a long straight Single line running from the 

 caudal end of this, along the caudal wing margin, formiug a caudal 

 boundary to the discal ciliation out beyond a point opposite to the 

 distal end of the venation. 



Marginal ciliation moderately short, not short. Marginal 

 vein subequal to the submarginal, or slightly longer, the postmarginal 

 vein absent, the stigmal vein well developed, slender, slightly 

 curved, terminating in an oblong uncus pointing disto-cephalad, 

 narrower than the marginal vein and between a fourth and a fifth 

 of its length. A small naked area disto-cephalad of the stigmal 

 vein. Posterior wings with discal ciliation similar to that of the 

 fore wing, its marginal ciliation also similar at the caudal margin 

 but at the cephalic margin the cilia are shorter and closer, The 

 posterior wing is shaped like the blade of some hunting knives. 

 Legs normal, tarsi 4-jointed. 



Antennae 10-jointed: scape, pedicel, 2 ring-joiuts, 3 funicle joints 

 and 3 club-joints; inserted about in the middle of the face and 

 somewhat above an imaginary line drawn between the ventral ends 

 of the eyes, the bulbs widely separated both from each other and 

 from the respective eye margins. Scape moderately thick, cylindrical, 

 nearly twice the length of the pedicel, subequal in length to the 

 long first Joint of the funicle; pedicel long obconic, slightly shorter
