5. Pseudocloeon veteris McDunnough 
Pseudocloeon veteris McDunnough (1924a:8). 
As McDunnough remarked when describ- 
ing this species, he based his description on 
old, faded specimens. Recently collected 
specimens, which could be studied while still 
alive, necessitate considerable change in the 
description of the color of this species. 
Mave.—Length of body 4.5-5.0 mm., of 
fore wing 5.0-6.0 mm. Head dull brown, 
frontal shelf hyaline; antennae dull tan, 
each scape white at apex; eyes orange-yel- 
low. Thorax bright orange-brown; yellow 
on prescutum, along outer parapsidal fur- 
rows, on scutellum, on pleural sutures, and 
covering the entire thoracic sternum; wings 
hyaline, faintly stained yellow at bases, stig- 
matic crossveins numerous, anastomosed; 
legs pale yellow, apex of each femur shaded 
with orange. Abdominal segments 2-6 yel- 
low, sometimes faintly suffused with tan, 
each tergite with a pair of submedian, red 
or red-brown dots, and usually a short, me- 
dian, red or red-brown, transverse stripe at 
posterior margin; segments 1-6 with black 
spiracular dots and longitudinal spiracular 
line usually present on either side; sternites 
1-6 yellow, with a median, dark brown spot 
at posterior margin of each and often black 
tracheal outlines extending ventrad from 
spiracles on anterior sternites; apical ter- 
gites dark orange-brown, sternites suffused 
with pale pink; genitalia white, apical for- 
ceps segment two and one-half times as long 
as broad; caudal filaments white. 
FEeMALE.—Length of body 5 mm., of fore 
wing 6 mm. Head and thorax light brown; 
legs light yellow, femora shaded toward 
apexes with pink or tan; abdominal dorsum 
light brown, with a pair of submedian, red- 
brown dots faintly visible on each tergite; 
abdominal sternum light tan, with a fairly 
large, black dot on meson of posterior mar- 
gin of thoracic metasternum and abdominal 
sternites 1-7.

34. NEOCLOEON Traver 
Neocloeon Traver (1932b: 365). 
The genus Neocloeon is similar to Cloeon 
in that the fore wings have relatively few

crossveins and single marginal intercalary 
veins, and the hind wings are wanting. 
In the males of Neocloeon, the fore tar- 
sus is approximately as long as the fore 
tibia, and either one is one and one-third to 
one and one-half times as long as the fore 
femur; the partly differentiated first tarsal 
segment of the hind leg is as long as the 
three apical, clearly differentiated segments 
combined. The stalk supporting the upper 
faceted portion of each compound eye is
