margin very strongly convexly rounded; clypeal foveae large and 

 deep and the clypeal sutures very distinct; supraclypeal area dis- 

 tinctly set off by shallow sutures running from the antennal foramina i 

 to the clypeal foveae; labrum with four digits; malar space about t 

 equal to the length of eye; eyes bare. Antennal scape clavate, slender [ 

 at base but becoming thicker toward apex, not quite reaching to an- • 

 terior ocellus; pedicel short, cup-shaped; funicle joints from first to ; 

 last successively decreasing in length, the first about three times as • 

 long as broad and about one and one-half times the length of the ! 

 second, the seventh about as long as broad ; club a little longer than i 

 the two preceding funicle joints combined, 3-jointed, the sutures ■ 

 usually distinct but not deep. Mesoscutum finely irregularly wrin- 

 kled, its lateral lobes smooth posteriorly; parapsidal grooves deep i 

 and not or very weakly foveolate; sutures separating axillae from i 

 scutellum strongly foveated, the carinae separating these foveae con- • 

 tinued over the axillae as very fine, widely separated, and more or 

 less parallel and oblique rugae ; scutellum longer than broad, dorsally 

 sculptured like the prescutum, smooth at apex, the transverse fold ! 

 not deeply impressed; propodeum about as long as posterior coxae, , 

 mostly smooth but usually with some obscure reticulation along the ■ 

 basal margin and down the middle, the spiracular sulci not foveated; , 

 pleura mostly smooth and polished. All coxae smooth; femora and I 

 tibiae moderately slender, without sculpture ; basal joint of hind 1 

 tarsi about as long as the three following joints combined; posterior ' 

 tibia apparently with only one spur. Forewing bare basally behind 1 

 the submarginal vein, this bare area with a triangular extension a i 

 little before the middle of wing and reaching approximately half : 

 the length of marginal vein, the rest of wing disk rather densely cili- ■ 

 ated; costal cell moderately broad and nearly uniformly ciliated; ; 

 marginal cilia extremely short, almost absent ; hind, wing vniiformly 

 ciliated from base to apex and with distinct marginal cilia. Seg- 

 ments of gaster apparently not incised medially, all except the first jj 

 short and subequal. Head, thorax, abdomen, and all coxae black, the ' 

 thorax with a slight bluish tinge and the gaster faintly coppery;: 

 femora all dark brown; trochanters, narrow apices of all femora, all 

 tibiae, all tarsi, the tegulae, and the antennae, yellowish testaceous, 

 the antennal flagellum becoming brownish toward apex; wings 

 hyaline.
