DESCRIPTIONS OF INSECT. 53 
wingpads are stout and almost entirely cover the abdomen. The ter- 
minal segment is still broad and flattened and bears two short spines, 
but the other characters have disappeared. 
True pupa of male. — The true pupa resembles the previous stage, 
except that the members are longer and slenderer, and the prominent 
anal style has appeared. The pupa is pale yellow and purplish in 
color, darkest about the base of the abdomen, the head, antennae, legs, 
wing sheaths, and style being almost colorless and transparent. The 
eye spots are dark purple. The antennae extend nearly to the middle 
femora, and are not curved under the body as formerly, but are applied 
close to the sides with the apex free. The anterior legs are held for- 
ward, reaching slightly beyond the eyes. The middle femora rest 
transversely to the body, projecting somewhat beyond the margin of 
the abdomen, while their tibiae form with them a right angle and reach 
nearly to the apex of the hind femora. The latter incline posteriorly, 
while the hind tibiae are applied close to the sides of the body, except 
toward the tip, and reach nearly to the base of the style. The style is 
rather stout, conical, obtusely pointed at tip, and about as long as 
posterior tibia?. Length, 0.8 mm , including style, which measures about 
0.15 mra . 
Mature male. — The general color is orange with a faint duskiness on 
the prothorax. The head is somewhat darker than the rest of the 
body. The eyes are dark purple, almost black. The antennae are 
yellow, somewhat obscure or smoky. The legs and style are dusky, 
the latter paler than the former. The thoracic shield is regularly 
ovoid, compressed anteriorly, dusky in color, with margin brown, more 
distinctly so anteriorly; transverse band narrow, brown. Antennae 
10-jointed, two basal joints shortest, second nearly globular, inserted 
in the first; joints 4 and 5 subequal, longer than any of the others; 
joint 6 next in length, and joints 3, 7, and 9 shorter and subequal; 
joint 10 still shorter, conical. Antennae somewhat hairy and nearly as 
long as the body of the insect. Wings faintly dusky, iridescent with 
yellow and green. Length of body about 0.6 ram ; style, 0.25 mm . 
Female, third stage. — After the second molt the females still appear 
pale yellow as before, with various larger and smaller transparent spots 
around the border of the body. The form is nearly circular, with 
greatest diameter averaging- 0.56 mm . The sucking bristles are very 
prominent and long, three times the length of the insect. The last 
segment in this stage has practically the characters of the mature female, 
as follows: There are two pairs of lobes, the terminal ones largest and 
nearly three times as broad as the other lobes. Terminal lobes are 
rounded at the apex and are distinctly notched near the middle of the 
external edge. The second pair of lobes is smaller and narrower, and 
is also notched externally. Between the first and second lobe on either
