36 THE FLORIDA ENTOMOLOGIST 
Mesothorax sculptured in the middle of the dorsal surface, sides bulging. 
Metathorax with nearly straight but diverging sides. Legs almost uni- 
formly brown, but little lighter apically. Wings uniformly brown except for 
a small colorless area about .2 the length from the base. Costal fringe of 
hairs scanty, absent from basal half. Veins rather prominent; costal 
bearing from 23 to 26 bristles, the others from 5 to 7, scale 5. 
Abdomen with a few short, brown bristles on segments 9 and 10. Dorsal 
surface faintly sculptured. The posterior margin of each segment is bor- 
dered with a series of about 20 rounded lobes. On the posterior segments 
these are more difficult to detect. 
Male not seen. 
Described from three females taken in Rabun Co., Ga., on 
Lespedeza, pine and bitterweed (Helenium). Readily recognized 
by the dark color, short intermediate antennal segments and 
crenated posterior borders of abdominal segments. 
Type in the author’s collection. Paratype in the National 
Museum.

Head about a third wider than long, widest behind the eyes. Cheeks 
arched, roughened, and bearing a few short, stiff bristles. All the dorsal 
surface behind the eyes striated with a half dozen anastomozing lines. 
Frontal costa deeply emarginate. A row of four minute bristles behind 
each eye and posterior ocellus. One in front of each posterior ocellus 
and a minute one near the inner anterior angle of each eye, opposite the 
anterior ocellus. Hyes dark, very large, occupying about .7 the length and 
.8 the width of the head, non-protruding, pilose, facets very large. Posterior 
ocelli very large, situated opposite posterior third of the eyes and touching 
their margins. Anterior about half the diameter of the posterior and about 
the size of the facets of the eyes; situated on the edge of the frontal emar- 
gination and directed forward. Mouth cone reaching about half way across 
the prosternum; sides almost straight up to the prolonged but rounded apex. 
Antennae 9-segmented, 2.2 as long as the head. Segment 1 short and thick, 
concolorous with the head; 2 lighter; 3 and 4 yellow with considerable 
orange pigment; 5 at least two-thirds yellow but dark brown at the extreme
