46 THE FLORIDA ENTOMOLOGIST 
MYCODIPLOSIS MOZNETTEI n. sp. 
By E. P. Felt, Albany, N. Y. 
The small midges described below were received from Mr. 
G. F. Moznette of the Federal Bureau of Entomology accom- 
panied by the statement that they were reared from the pyriform 
scale, Pulvinaria pyriformis Ckll., as many as three individuals 
being reared from one scale insect. The larvae devour the eggs 
of the female scale and when full grown construct small cocoons 
underneath the scale of the host. One slide containing a number 
of females was labelled Miami, Fla., November 26, 1921, G. F. 
Moznette, Avocado. The other slide bears the date of Decem- 
ber 2, 1921, and similar information. 
The species appears to be closely related to three other pre- 
daceous forms in this genus, namely, M. acarivora Felt, M. cocci- 
divora Felt and M. pulvinariae Felt, from all of which it is eas- 
ily separated by the distinctly shorter stems of the male flagellate 
antennal segments. . 
Male: Length 1.25 mm. Antennae a little longer than the 
body, thickly haired, probably yellowish brown, 14 segments, 
the fifth with the stems each with a length one half greater than 
the diameter, terminal segment, basal enlargement roundly disk 
shape, the basal portion of the stem short, the distal enlarge- 
ment broad, broadly rounded, obtuse apically: Palpi, first seg- 
ment subquadrate, the second with a length about twice its di- 
ameter, the third more slender; body and halteres probably pale 
yellowish; legs probably pale straw; Genitalia, basal clasp seg- 
ment moderately stout; terminal clasp segment about one half 
the length of the basal clasp segment, moderately stout, dorsal 
plate longer, deeply and narrowly emarginate, the lobes broadly 
rounded; the ventral plate long, broadly rounded apically. 
Female: Length 2 mm. Antennae about three fourths the 
length of the body; sparsely haired, probably pale straw, four- 
teen sub-sessile segments, the fifth with a stem one fourth the 
length of the cylindric basal enlargement which latter has a 
length two and a half times its diameter ; terminal segment with 
a length three times its diameter and apically a short, obtuse 
process; palpi nearly as in the male; body “pinkish”; halteres 
presumably pale yellowish; the legs probably pale straw; ovi- 
postor about one fourth the length of the abdomen, stout, the 
lobes broadly rounded apically.
