equal in length, gradually decreasing, their caudal margins straight; 
segment six sometimes slightly longer than segment three; segm'ent 
eight conical, subequal in length to segment seVen. Ventrad and 
dorsad, caudal margins of the segments with a slight whitish 
pubescence or fringe. 
Fore wings normal, with the usual densfe discal ciliation, the sub- 
marginal vein slenderer than the marginal and about a third longer, 
widening at its curVe; the marginal vein normal, thrice thicker than 
the submarginal vein at its middle and distinctly wider than either 
the postmarginal or stigmal veins and a fourth longer than the 
former and a third longer than the latter; postmarginal vein dis¬ 
tinctly longer than the stigmal vein which is slightly curved, bearing 
a moderately large club with a cuneate uncus from its cephalo-distal 
margin; marginal cilia short. Hind wings ciliate distally. Fore 
wings broadest at points opposite the knob of the stigmal vein. 
(Fig. 3). 
Legs normal, slender, the tibial spurs all single, moderately stout, 
the cephalic femora stout but not abnormally or conspicuously so, 
the tarsi all 5-jointed, the proximal joint of the caudal tarsi over 
twice the length of the caudal tibial spur and about twice the length 
of the second tarsal joint, the fourth joint, as usual, smallest. 
Left mandible 3-dentate, the inner (mesal) tooth broadest, nearly 
truncate, the second tooth intermediate in size and shape, acutely 
dome-shaped and the third, outer (lateral) tooth longest, slenderest, 
acute, subfalciform. (Fig. 2). Eight mandible 4-dentate, the teeth 
gradually lengthening laterad, the mesal one shortest, obtusely convex, 
the second longer, obtusely conic, the third still longer, subacutely 
conical, the fourth or lateral tooth longest, acute, subfalciform. 
(Fig. 2). Maxillary palpi 4-jointed, the apical joint longest, twice the 
size of joint three, clavate, the proximal joint shortest. Labial palpi 
3-jointed, the middle minute, the others subequal. 
$. The same. The adbomen flat, depressed, from dorsal aspect 
elliptical-oval, with a large yellowish white artea in the dorsal and 
ventral basal region. Petiole shorter than in the female, not as 
noticeable, the segmentation of the adbomen not as distinct. Antennae 
inserted slightly higher up on the face, slenderer. Mandibular and 
other characters the same as in the female. Similar to male 
Pteromalus Swederus or nearly so. 
A genus of moderately stout, metallic green hyperparasites 
with the general aspect of Pteromalus and about the same stature. 
On account of the insertion of the antennae, high up on the 
head, near the middle of the face and not especially near the
