WINTER NUMBER ~ 39 
margins; anterior directed forward. Mouth cone reaching about half way 
across the prothorax, abruptly constricted near the base but very broadly 
rounded at the apex. Antennae 8-segmented. Segment 1 cylindrical, con- 
colorous with the head; 2 urn-shaped, abruptly constricted to a very broad 
pedicel, concolorous with the head except the yellowish brown apex; 3 
obovate, narrower than either 2 or 4,gradually narrowed to a broad base, 
yellowish brown, darker along the sides and with a broad, colorless band 
at the apex, usual sense cones present but colorless and inconspicuous; 4 
ovate with a short, broad pedicel, basal third concolorous with 3, but re- 
mainder darker, the colorless collar at the apex narrow; 5 and 6 barrel- 
shaped, pedicel shorter and narrower than in 4, dark brown; 7 cylindrical, 
sides but slightly arched and converging slightly apically; 8 unusually 
large, margin conspicuously crenate. All antennal bristles thin, pale brown 
and inconspicuous. 
Prothorax (including coxae) about twice as wide as long, trapezoidal in 
outline, much widened posteriorly, posterior margin arched, posterior angles © 
abruptly rounded and bearing a pair of sharp-pointed, light colored bristles 
of medium length; coxae each bearing one short, dark, thick bristle and a 
pair of very short, thorn-like spines; anterior angle with a short heavy 
bristle. 
idesothorax broad, with very acute anterior angles and nearly straight 
sides which converge slightly posteriorly. Mesothorax somewhat narrower, 
sides more arched and more constricted posteriorly. Wings rather weak, 
membrane scarcely reaching the eighth abdominal segment, quite narrow 
except at the extreme base, unusually deeply constricted for a Haplothrips, 
to a diameter about half that nearer the apex. Fringing hairs moderately 
long, seven interlocated ones. Legs rather slender, dark, fore femora but 
little thickened; fore tarsus with a small tooth. 
Abdomen long and slender, destitute of conspicuous bristles, those of the 
ninth segment shorter than the tube. Tube of moderate size, sides slightly 
concave, terminal bristles about as long as the tube. 
Male not seen. 
- Described from two females taken from coarse marsh grasses 
at Clayton. Type and paratype in the author’s collection. 
Hoplan¢rothrips flavoantennis (Wats.) 
The female only was originally described. (Liothrips flavo- 
antennis, Ent. News, March 1916, p. 129.) A male was collected 
in Georgia. 
Male. Color uniformly dark brown except antennal segments 3-8, which 
‘are bright yellow. (In some females also segment 8 is yellow, also segment 
2 may be brown.) 
Measurements: Total length 1.7 mm.; head, length .235 mm., width 
.18 mm.; prothorax, length .13 mm., width including coxae .29 mm.; meso-
