28 THE FLORIDA ENTOMOLOGIST 
terior pair opposite the anterior third of the eyes and touching their mar- 
gins. Mouth cone short and very bluntly rounded, scarcely reaching the 
middle of the prosternum, slightly swollen at the base. Antennae twice as 
long as the head. Segments 1 and 5-8 dark, concolorous with the head; 2 
and 4 lighter brown; 3 yellow, clear at the apex. No sense cones on the in- 
ner surface of segment 3, those on 4, 5 and 6 thick but colorless. Bristles 
light colored and short. 
Prothorax about as long as the head, sides conspicuously bulging across 
the coxae where they bear each a heavy, knobbed, but light-colored bristle; 
posterior angles much contracted, each bearing a similar bristle. 
Pterothorax subrectangular, sides straight and nearly parallel. Legs 
rather long and slender. Femora dark brown, concolorous with the body. 
All tarsi and tibiae light brownish yellow, the latter shaded with brown on 
the outer surface. Fore femora considerably enlarged. Fore tarsi with 
a strong curved tooth and a smaller straight one. Wings well developed 
but not reaching the tip of the abdomen. Membrane clear in distal half 
but the proximal half of fore wing clouded with brownish gray. Fore wing 
much contracted in the middle, destitute of prominent veins or bristles; 
fringing hairs numerous and fairly long, 4 or 5 interlocated ones. 
Abdomen rather long, sub-cylindrical, conspicuous bristles on only the 
last two segments but a few of these are quite long, light brown. 
Described from two specimens; one obtained from sweeping vegetation 
including scrub oak at Daytona Beach Aug. 1919, and another from beating 
Basswood foliage Tilia americana at Gainesville, May 1920. 
Male similar to the female but the fore femora more enlarged and the 
tarsal spine larger. 
Described from a single specimen collected from underneath the bark of 
an oak tree (Quercus falcata) at Orlando Oct. 1919. Stated by Mr. Funk 
of the U. S. Drug Garden who called our attention to this insect, to have 
been abundant on the oaks in the spring.

* General color grayish brown with a little red and purple hypodermal 
pigment. Fore femora and tarsi lighter. 
Measurements: Total body length 1.17 mm.; head, length 0.19 mm.; width 
0.17 mm.; prothorax, length 0.20, width including coxae 0.288; mesothorax, 
width 0.37 mm.; abdomen, width 0.24. mm. Antennae, segment, 1, 32; 2,

Head 1.1 times longer than broad, sides slightly bulging, parallel or 
slightly converging posteriorly, sparsely pilose, post-ocular bristle short and 
pointed, not reaching the middle of the eye. Hyes moderately large, occupy- 
ing .4 the length and .7 the width of the head. Ocelli large, posterior pair 
set in front of the middle of the eyes and touching their margins. Mouth 
cone evenly and bluntly rounded, reaching a little past the middle of the 
prosternum. Antennae 1.5 times as long as the head; almost uniformly 
grayish brown, segment 2 a little darker and segment 3 a little lighter than 
the others; sense cones and bristles pale and inconspicuous. 
Prothorax shorter than the head, nearly 1.5 times as wide as long, trap- 
ezoidal in outline; posterior angles well rounded and each bearing a pair of
