WINTER NUMBER 55 
segments with a narrower peduncle than 4; 6 conical, but little constricted 
at the base; 7 cylindrical, considerably shorter than 8; 8 conical. 1 al- 
most colorless, 2 almost uniformly light brown except the paler peduncle; 
3 light Marguerite yellow (Ridgeway’s color chart) clouded with darker 
gray in the apical third; apical half of 4 and 6 mummy brown (Ridgeway) 
basal half of 4 and often all of 5 Marguerite yellow, 5 sometimes clouded 
with brown in apical third, 7 and 8 a little lighter than 6. 
Prothorax wider than iong and wider and longer than the head, sides 
strongly arched. One bristle on each anterior angle and a pair on each 
posterior angle are unusually large and strongly curved. The longest on 
the posterior angle often reaches a length of 80 microns or nearly half 
the width of the prothorax; another stout bristle (but only about a third 
as long) at the anterior angle; on the anterior margin are a pair of 
bristles nearly as stout and four pairs of minute colorless ones. 
Pterothorax much wider than the prothorax, anterior angles evenly 
rounded to the posterior margin of mesothorax. Metathorax narrower, 
sides nearly straight and parallel. Two large bristles and two smaller ones 
between the wings and two large ones and about 12 smaller ones along 
the anterior margin. Legs light brownish yellow, considerably lighter than 
the body. Tibiae provided with a pair of stout spines near the apex. 
Wing membranes reaching to about abdominal segment 9, fore pair very 
light grayish yellow, provided with heavy bristles, about 25 on costa, 
19-21 on anterior vein, and from 14 to 21 (usually 19) on posterior. 
Abdomen, rather short and thick, widest at about segment 8, thence 
rounding rapidly to tenth segment. The posterior segments (5-9) pro- 
vided with heavy, but comparatively short, curved bristles at the posterior 
angles. The 10th segment split open for not over a fourth of its length, 
tipped with orange at the extreme apex. Provided with about a dozen 
large straight brown bristles which extend far beyond the tip. 
Male. Much smaller than the female, about 0.8 mm., pale yellow. Head, 
length 0.11 mm., width 0.15 mm.; prothorax, length 0.15 mm.; width 0.19 
mm.; mesothorax, width 0.20 mm.; abdomen, width 0.15 mm. Antennae, 
Sepmentel, 25> 2,39; 3,49; 4,46; 5, 38; 6, 46; 7, 7; -8, 11 microns: 
Total length 0.26 mm. Wings with about 22 strong bristles on costa, 16 
on anterior vein and 13 on posterior. Second segment of antennae much 
lighter in color than in female; lighter than the first. Testes yellow- 
ish brown by transmitted light, yellow by reflected. 
Larvae brownish yellow, legs and tip of abdomen lighter. Eyes dark. 
Described from thirty females and four males collected by Dr. 8. C. 
Bruner in Santiago de las Vegas and on the Peninsula de Guanahacabibes, 
Cuba, on oranges, avocadoes, hibiscus, Moringa. Type in the author’s col- 
lection. 
Close to F’. cephalica melanommatus Bagnal, of which it is probably only 
a Cuban race, but differs in the color and form of the second antennal 
segment which projects but little dorsally and not at all forward over 
segment 3, in the larger number of spines on the posterior vein of the 
fore wings (in both sexes) and in the split end of the last abdominal 
segment, and especially in the long, stout, curved bristles. 
It can be told at a glance from F’. cephalica masoni by the lighter color 
and the character of the second antennal segment.
