AET. 8 NEW HYMEKOPTERA, SUBFAMILY ANTEONINAE EENTON 13 



CHELOGYNUS PROPODEALIS, new species 



Figs. 25 and 10 



Female. — ^Length, 2.Y mm. General color black except as noted 

 below. Head wider than long (8:5); surface of vertex polished with 

 scattered very fine hairs; ocelli in equilateral triangle, lateral ones 

 same distance from occiput as eyes, a distinct carina extends from the 

 median ocellus to between the bases of the antennae; head extended 

 and sides strongly convergent behind the eyes; occiput truncate, 

 mandibles fuscous; antennae testaceous, short, being scarcely longer 

 than head. (Fig. 25.) Pronotum, mesoscutum and scutellum smooth 

 and polished with no visible sculpturing and with fine scattered 

 white hairs; pronotum narrower than mesoscutum and slightly 

 shorter than this (4:5); mesoscutum without parapsidal furrows; 

 scutellum transverse, much wider than long, rugose along its posterior 

 margin; postscutellum rugose, shorter than scutellum, being almost 

 linear; legs testaceous except posterior femora and tibiae and also 

 middle tibiae, which are brownish, posterior femora darker on the 

 stalk than the club ; chela as in Figure 10 ; wings with two transverse 

 darker bands, the first and larger extending from the pterostigma 

 half \^ay to the tip and almost to opposite margin of wing, the second 

 and smaller extending across the apex of the basal cells, radius angu- 

 lar, proximal part much longer than distal. Propodeum rugose, 

 posteriorly sharply truncate, this part having a large, smooth, 

 median area, bounded by a carina, the enclosed area being in the 

 shape of a five-sided polygon, the sides of which are longer than the 

 divisions at either end. Abdomen fusco-piceous, smooth, polished. 



Type locality, — Santarem, South America. 



Described from one specimen.

Female. — ^Length, 2.1 mm. General color black, except as noted 

 below. Head wider than long (8:5); surface of vertex dull with 

 short scattered dark hairs ; ocelli in an equilateral triangle, lateral 

 ones being about same distance from occiput as eyes, a distinct carina 

 extends from median ocellus to between bases of antennae ; head con- 

 vergent and rounded behind the eyes; occiput truncate, arcuate; 

 mandibles black except teeth, which are brown; antennae fuscous, 

 except sixth to ninth joints, which are testaceous, short but notice- 

 ably longer than in propodealis. (Fig. 24.) Pronotum, mesoscutum 

 and scutellum smooth with scattered short dark hairs; pronotum 

 narrower than mesoscutum and shorter than this (2:3) ; mesoscutum. 

 with parapsidal furrows convergent and extending about half way 

 towards its posterior margin ; scutellum transverse, two-thirds length
