SPRING NUMBER LG 
dle. Legs rather long, concolorous with the body; fore femora greatly 
enlarged: all femora with a small, stout anteriorly directed, triangular 
tooth at the apex within. Fore tarsi with a very large strong tooth within. 
This tooth is nearly as large as the rest of the tarsus. 
Wings reaching abdominal segment 6 or 7; membrane clear, distinctly 
narrowed in the middle; 23 interlocated hairs on the margin of the fore 
pair. 
Abdomen widest at the base of the first segment, thence rounding to the 
base of the rather large tube; no conspicuous bristles on the anterior seg- 
ments, those on the posterior about as long as the tube but pale. Those 
at the end of the tube pale and slender of medium length, the longest 
over half the length of the tube. 
Measurements: Head, length 0.3 mm., width 0.21 mm.; prothorax, 
length 0.17 mm., width, including coxae, 0.42 mm.; Pterothorax, width 0.45 
mm.; abdomen, width 0.5 mm.; tube, length 0.19 mm., width at the base 
0.07 mm., at the apex 0.038 mm. Antennal segments 1, 27; 2, 57; 3, 67; 
4, 64; 5, 67; 6, 59; 7, 56; 8, 48 microns; total length 0.47 mm. 
Described from a single female taken in sweeping shrubs in the “flat 
woods” near Orlando, Fla., Feb. 1919. It resembles H. jonesii Karny in 
size, color, antennae and the presence of the femoral teeth, but differs 
in numerous characters including the size of the spine on the fore tarsi, 
short mouth-cone, and absence of spines near the base of the femora below. 
Type in the Experiment Station collection.
