148 Psyche [August 
Abdomen sessile, (lateral aspect) conic-ovate, concave dorsad longi- 
tudinally, convex or ridged along the meson ventrad and pointed caudad, 
with the tip of the ovipositor exposed, not compressed, subdepressed, as 
long as the head and thorax combined; (dorsal aspect) abdomen ovate, 
ending in a sharp point, widest at about the apex of the third segment, the 
second segment longest, occupying a fourth of the surface, segment 3 next 
longest, excepting 7 and 8, a third shorter, segments 4 and 5 subequal, 
slightly shorter than segment 3; the sutures between segments 2 and 3 ob- 
secure; segment 6 subequal to 3 but distinctly narrower, segment 7 triangu- 
lar with the apex of the triangle caudad, at the meson three-fourths the 
length of segment 2; segment 8 pointed conical, as long as segment 6, the 
point of the ovipositor protruding from it slightly; segments 7 and 8 
pubescent. Abdomen somewhat variable in shape, sometimes slightly 
triangularly produced ventrad at base. 
Legs normal, the anterior and posterior femora with their caudal mar- 
gins convexed in the middle, but not conspicuously or abnormally so, the 
tibial spurs all single, the cephalic ones largest, curved, notched at the 
apex; caudal tibial spurs not half as long as the slender proximal tarsal 
joint, which is longest, the fourth caudal tarsal joint as usual, shortest, the 
third nearly as short as the fourth, the second about half as long as the 
first and longer than the fifth. Caudal coxe largest, their lateral aspect 
flat, the intermediate coxe by far smallest. The cephalic coxe subconical. 
Fore wings normal, widest at a point opposite the stigmal knob, usually 
ciliate in the disk, the apex rounded; submarginal vein slender, its whole 
length gently concavely curved, slightly enlarging as it nears the marginal 
vein, about a third longer than the latter; marginal vein broadened, clavate, 
its base twice the width of the postmarginal vein, gradually narrowing 
distad, dark, nearly twice the length of the postmarginal and_stigmal 
veins; the latter two veins, slender, short, subequal in length, the post- 
marginal vein slightly longer, the angle between them about 45°; the 
stigmal vein straight, bearing a small ovate knob with an uncus proceeding 
from its cephalo-distal margin near apex. Marginal cilia absent, except- 
ing along the venation and distad along the caudal margin where they dis- 
appear as the apex of the wing is neared; short. (Fig. 3). Posterior wings 
widest before their middle; the cephalic margin of the wing is nearly 
straight, obliquing distad; the caudal margin broadly convex, broadly 
emarginate towards base, sloping distad but the apex obtuse; discal cilia 
dense, but delicate and minute; marginal cilia moderate in length on the 
caudal margin. Venation usual; about 22 hooklets. Maxillary palpi 
4-jointed, the last joint much the longest, cylindrical oval. Labial palpi 
3-jointed. 
Male—The same. Eyes smaller, about the length of the gene, ovate; 
antenne more slender, filiform, more noticeably hairy, pilose, more loosely 
jointed, the distal funicle joints subpedunculate; 14-jointed, with two ring- 
joints and a 4-jointed club; the funicle but 6-jointed, the first funicle joint 
very long, cylindrical, narrowed in the middle, the joints shortening distad,
