8 Psyche [March-June 
linose; ocellar area very little raised, denuded, shiny black, not 
extended downward; frontal callus low, black, transverse, with 
nearly straight sides which are separated from the eyes by nar- 
row pollinose orbits. Fronto-clypeus shiny honey-yellow, with 
infuscated blotches; upper half of cheeks, very narrow inner 
orbits and entire outer orbits grey pollinose; facial pits yellow; 
upper lateral areas (above the pits) flattened convex, not coni- 
cal. Antennae dirty-yellowish on segment 1, fuscous-brown to 
blackish on 2 and 3, very slender, much longer than fore fem- 
ora; segment 1 about one and one-third times the length of 2; 
3 scarcely longer than 1, its basal portion very little swollen; 
1 and 2 cylindrical, not swollen, equally thick both from above 
and in profile. Palpi yellowish-brown. Thorax black, fairly 
shiny, lightly covered with grey pollinosity, which forms two 
narrow, continuous median lines on the dorsum and is more pro- 
nounced on the pleura and on the sides of the dorsum between 
the wings and the shoulders; no pleural stripes nor spots; 
scutellum shiny black. Legs mostly infuscated to black; much 
of fore femora, extreme tips of mid and hind femora, and entire 
hind tarsi dirty yellowish-white; all tibiae flattened convex, 
moderately widened. Wings fairly cloudy over most of the 
clearer areas, decidedly hyaline only in the two basal and the 
anal cells; darker markings as follows: costal and subcostal 
cells, very narrowly connected with the apical spot, which is 
poorly defined but fills in most of the apex of the wing; it is 
darkest close to the costa and fades gradually toward the 3d 
posterior cell; a very narrow, nearly hyaline streak divides it 
from the distal margin of the crossband, beginning well inside 
the marginal cell a short distance from the costa; cross-band 
with nearly straight distal edge, far from the fork of the third 
vein, divided at the hind margin by an ill-defined, semi-hyaline 
spot covering much of the 5th and the median portion of the 
4th posterior cells; center of discal cell also somewhat paler; 
base of wing, extreme tips and bases of both basal cells and 
narrow upper margin of anal cell infuscated; stigma well de- 
fined, blackish-brown; anal cell broadly open at apex. Halteres 
black. Abdomen: 1st tergite yellowish-white, with a narrow 
black apical margin; 2d tergite yellowish-white over a little 
more than anterior half, the black hind portion extending for- 
ward along the sides; 1st and 2d sternites mostly pale yellow- 
ish; remainder of abdomen shiny black, without markings;
