deum, and abdomen except for basal segments, black. Basal ab- 

 dominal segments yellow. Fore and middle legs mostly straw- 

 colored to pale yellow. Femora of fore legs on outer aspect at base 

 with some fuscous. Femora and tibiae of hind legs mostly blackish, 

 the extremities yellowish. Apical tarsal joints faintly brownish. 

 Ovipositor sheaths, as seen from beneath, brownish. 



In the tag-mounted specimens, the head is shriveled, face deeply 

 sunken and frontovertex folded. Antennal sockets with their upper 

 margin about tangent to basal ocular line and spaced about as far 

 apart as they are above oral margin. Cheeks without discernible 

 suture. Posterior ocelli less than their own diameter from eye 

 margins and about the same distance from occipital margin. Poste- 

 riorly the eyes contiguous with occipital margin. 



Antennal scape of usual shape, slightly fusiform, about four 

 times as long as wide. Pedicel about one and one-half times as long 

 as wide and distinctly shorter than the first funicle joint. First 

 funicle joint slightly longest, slightly more than one and one-half 

 times as long as wide; following funicle joints successively very 

 slightly shorter and wider, the third only slightly longer than wide. 

 Club as seen in tag mounts slightly wider than funicle. In the 

 balsam mount the antenna is oriented so that the club appears 

 slightly narrower than the funicle (fig. 58). 



Mandibles broad and truncate at apex, the margin very slightly 

 and indistinctly incised. 



Scutellum a trifle wider than long and as long as mesoscutum. 

 Spiracles slightly oval, almost rotund. Abdomen of moderate size; 

 in tag-mounted specimens after shrinkage, longer than wide and 

 not as long as thorax. Ovipositor concealed. In the cleared balsam- 

 mounted specimen, the ovipositor is seen to be less than one-half 

 as long as the abdomen (fig. 12). 



Fore wings with an infuscated area under distal half of marginal 

 vein. Marginal vein longer than submarginal ; postmarginal vein 

 absent; stigmal as shown in Figure 86. Ciliation of the disk slightly 

 coarse on basal half and moderately dense. 



Mesoscutum clothed with numerous short, black setae arranged 

 in somewhat irregular, longitudinal files; setae on lateral and pos- 

 terior margins stronger and about same size as the two setae located 

 on each axilla. Each parapsis with three setae. Scutellum about 

 as densely setose as mesoscutum and with a pair of long apical 

 bristles. Middle femur at apex beneath with a strong black spine 

 and a few smaller pale spines; base of the tibia with a few short 

 spines. Eyes with short fine setae. Face and cheeks with yellowish 

 setae, those on the frontovertex slightly stronger and blackish. 



Measurements in mm. : Length 1.3. Scape 0.1352 long by 0.0336 

 wide. Pedicel 0.0520 long by 0.0344 wide. First funicle joint
