322 HYMENOPTERA. 



shorter than proximal funicle joint. Ovipositor distinctly exserted but 

 not for any length (about a third or less of the body of the abdomen). 

 Sculpture of body polygonal figures, scaly. Scutellum with a line of 

 round fovese before its apex, following its outline ; parapsidal furrows 

 complete, widely separated, nearly straight; fore wing moderately 

 densely ciliate but naked near the cephalic margin and for some dis- 

 tance out from the marginal vein excepting for a single line of cilia in 

 the latter place and two short lines leading along the margin from the 

 marginal vein in the former. Marginal cilia where longest, only be- 

 tween a third and a half of the greatest wing width. Posterior wing 

 very narrow and slender, linear, without discal ciliation at all but a 

 line of cilia along each wing edge ; the marginal cilia of the posterior 

 margin over four times the width of the wing blade. Fore wing dis- 

 tinctly fumated its entire length. Middle of metathorax elevated as in 

 bifasciatipenne , the margins acute. Proximal tarsal joint as long as 

 the other three united. Metathoracic spiracle minute, round. There 

 is a carina leading from it, having its origin just off (caudo-mesad) 

 of the spiracle, running nearly caudad, and another shorter one, obli- 

 que, running caudo-mesad from the lateral aspect toward the caudal 

 end of the first, forming a more or less obscure V-shaped figure. 

 Fore wings with about fifteen longitudinal lines of discal cilia, each 

 cilium moderately long and the lines separated.

Polynema rufescens Ashmead. 

 Ashmead, 1904, p. 521. 



From the single male tagmounted type specimen in the 

 United States National Museum collections, I have made the 

 following observations. The specimen was labelled "Poly- 

 nema rufescens Ashm. <3^ type, d^ type No. 6595, U. S. N. 

 M. Bnito Prov., Pernmbuco, Brazil. Feb. 83". 



Body brown. Fore wings deeply fumated. Parapsidal furrows 

 complete, curved, widely separated. Body shining, the sculpture 

 nearly imperceptible, delicate, polygonal figures. Metathorax with 

 the usual central triangular elevated portion, whose margins are cari- 

 nated, and with two lateral carinse, the first prominent, originating 

 cephalo-laterad of the minute circular spiracle and running caudo- 

 mesad to the mesal elevation and in front of the spiracle ; the second 

 is nearly parallel with the first but caudad of the spiracle, originating 

 in the lateral aspect directly laterad of the spiracle, and running in a 

 gentle convex curve caudo-mesad as to general direction but the curve 

 finally caudo-laterad. The spiracle is between these, nearer to the 

 first. Antennae filiform, 13-jointed, the funicle joints with numerous 

 long carinse, stiff grey pubescence and gradually increasing in length
