34 Psyche [March-June 
wedge-shaped yellow spot or stripe upon the metapleurae. Ab- 
domen: chiefly yellowish, the first segment wholly yellow, second 
segment light brownish-yellow throughout with a slender but 
inconspicuous scarcely darker brownish line down the middle. 
Third segment yellow laterally on the basal two-fifths; in the 
middle and upon the entire remainder of the segment light 
reddish-brown. Whole of the fourth segment and the hypo- 
pygium reddish-brown. The hypopygium seen from above is 
bulbous at the base and drawn out into an abrupt point, there- 
fore the hypopygium proper viewed from above looks somewhat 
like an acutely pointed equilateral triangle. The pile of the ab- 
domen is pale yellowish upon the first and second segments; on 
the remainder of the segments it is brown but not black. The 
abdomen is rather slender in shape. Legs: anterior legs almost 
wholly light yellow; last four joints of tarsi pale brown, the mid- 
dle pair exactly the same ; hind femora brownish on the basal fifth 
and obscurely brownish before the apex. Hind tarsi brown, ap- 
pearing darker because of the black pile, the apical joint yellow. 
Hind femora ventrally with sparse black spinules throughout its 
whole length which near the apex are arranged in a single row on 
each side. Wings: upon the costal, and upon the subcostal and 
marginal cells, clear yellow as far as the end of the costal cell. 
The outer or stigmal portion of the subcostal cell and the outer 
part of the marginal cell sharply dark brown, the color extended 
narrowly along the apical margin of the submarginal cell. The 
brown of the subcostal cell is definitely darker than that of the 
marginal cell. Also the fifth longitudinal vein throughout its 
posterior section and base is margined with brown. Subapical 
cross vein strongly sigmoid; loop of third vein deep, rising 
vertically. 
Holotype: No. 23803, one male. Bella Vista, Panama, Au- 
gust 8, 1924, N. Banks collector. 
This species is somewhat similar to cothurnatus Bigot from 
which it appears to differ in a number of particulars. It is con- 
siderably smaller and the tarsi are pale brown, tending rather to 
be yellowish instead of black as described by Bigot. Apparently 
the pleurae of cothurnatus are black whereas here they are reddish, 
with a single large yellow and a single small yellow stripe. The 
abdomen in this species is more extensively yellowish, in cothur- 
natus reddish with the posterior borders brown. I have a speci- 
men from Panama quite different from the present specimen
