General color variable, dilute brownish black ; scape, pedicel, caudal coxre, 

 trochanters, three proximal tarsal joints and the cephalic tibiae pallid yellowish ; 

 flagellum of the antennae, cephalic and intermediate cox;e, femora, intermediate 

 and caudal tibiae and the venation dusky black, the club joint darker. Wings 

 hyaline, excepting the slightly clouded middle portion of the posterior wings. 

 Abdominal petiole yellowish brown to yellow. Eyes reddish, ocelli pink, 

 Gular surfaces yellow% Abdomen reddish brown, smooth, shining, impunctate. 



Fore wings in general as in the preceding species but decidedly more 

 slender and the discal cilia are distinctly stronger and coarser, coarse, less 

 dense, being about half as many in a transverse row across the widest part of 

 the wing (about ii to 12 longitudinal lines, counted from one margin to the 

 other) ; posterior wings, however, as in the preceding species but the two lines 

 of discal cilia near the margins are less distinctly paired. 



Abdomen conic-ovate, longer than the combined length of the head and 

 thorax, the hypopygium extending somewhat beyond the apex but the ovi- 

 positor not at all exserted. Legs as in the preceding species. Tibial spurs all 

 single, the intermediate ones smallest, the cephalic ones long, comparatively 

 stout and forked at its tip, forming a strigil with the longitudinal row of 

 brush-like bristles along the ventral aspect of the proximal joint of the cephalic 

 tarsi. \'entrad of the antennal bulbs, the face bears sparse hispid pubescence, 

 the antennal bulbs widely separated, thrice the distance from each other than 

 each is from the respective eye margin. Head (cephalic aspect) triangular, the 

 face concave, margined laterad but the cheeks rounded. Eyes ovate. Parap- 

 sidal furrows distinct, complete, short, curved. Vertex broad but declivous 

 cephalad of the cephalic ocellus, just caudad of that ocellus, acute transversely ; 

 ocelli in an obtuse angled triangle on the caudal half of the vertex, the lateral 

 ones near the occipital margin, not near the eye margins, but nearly thrice 

 farther separated from each other than each is separated from the eye margin 

 and nearly twice the distance apart than each is from the cephalic ocellus, the 

 latter about in the center of the vertex. Lateral margin of the eye slightly 

 concave. The " vertexal carina" present (cephalic aspect), apparently a trans- 

 verse grooved line along the cephalic margin of the vertex, abruptly changing 

 angle laterad and proceeding obliquely caudo-laterad along the eye margin and 

 then (dorsal aspect) at the caudo-mesal angle of the eye, changing angle, pro- 

 ceeding obliquely caudo-mesad to the occipital margin where it is lost (caudal 

 aspect), apparently, however, in the foraminal dejiression curving convexly, 

 caudo-ventrad or beyond the occipital margin, curving around to join the cor- 

 responding part on the opposite side and thus forming one continuous groove. 

 This groove separates the lateral ocelli from the eye margins. (Dorsal aspect), 

 occipital and cephalic margins of the vertex concave, the head longer (axially 

 or cephalo-caudad) at the lateral margin by about a fourth, than at the meson, 

 wide behind the eyes, the face scooped out between the eyes. Body very 

 faintly sculptured, practically smooth. Scutellum hemispherical, smooth, at its 

 caudal (apical, distal) fifth, following the apjcal margin of the sclerite is a 

 convexly curved line of uniformly round dot-like punctures or fovere. Meta- 

 thoracic spiracles minute, circular, margined, no sulcus ; metathorax polished, 

 with no carinac. Legs hairy, especially the tibiae.
