HABITS AND LIFE HISTORY. 47 
The males are somewhat larger than the females, elongate, pyriform. 
The eyes are prominent, purple in color. The legs and antenna 
with the females, are wanting. The general color of the body is yellow, 
with the irregular transparent spots noted in the case of the female. 
The greatest diameter in both sexes is less than one-half a milling 
and in the characteristics of the terminal segment both agree, practi- 
cally, with the adult female. 
Male pro-pupa. — With the second molt the male assumes a form fore- 
shadowing- the true pupa, which may be called the pro-pupa. 1 The 
form is elongate oval ; length. 0.5 mm . The color is very pale yellow, with 
the antenme, limbs, and wingpads, and two or three terminal segments 
of the abdomen, colorless. The legs and antennae, as noted, have 
reappeared, and also prominent pads foreshadowing the wings of adult. 
The eyes are dark purple and placed close together. The antenme are 
very stout, and curved closely around the edge of the body as far as 
the anterior legs, where they bend inward. The wingpads are stout 
and almost entirely cover the abdomen. The terminal segment is still 
broad and flattened and bears two short spines, but the other char- 
acters 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, antenna-, legs, 
wing sheaths, and style being almost colorless and transparent. The 
eye spots are dark purple. The antenme 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 tibia? 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 
posterior tibia-. Length, O.S mm , including style, which measures about 
0.15 mm . 
Mature male. — The general color is orange with a faint duskiness on 
theprothorax. The head is somewhat darker than the rest of the body. 
The eyes are dark purple, almost black. The antenna 1 are yellow, some- 
what 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 ante- 
riorly: transverse band narrow, brown. Antenna' 10-jointed. two basal
