more or less marked; the most variable trac- 
ing is the spot, without a distinct margin, 
which is found at the apex of the cell and 
the color of which varies from greenish white 
to a lighter shade of the background color. 
When they are well marked three transverse 
basal bands which are a little darker than 
the background color can be distinguished. 
There are also a slightly arched line which 
passes through the middle of the spot, and a 
line that starts at the apex runs almost paral- 
lel to the costa as far as Cun/ and is there 
directed toward the inferior edge of the wing. 
The space outside this line is lighter in 
color. 
The posterior wings are black with a gray 
base. A lengthened spot, more or less bright 
pink, and a marginal band of white spots, 
typically triangular extend from the anal 
angle to the middle of the wing; each spot 
is found between veins. 
The underside of the anterior wings is 
grayish, and the medial space is black with 
three whitish spots; the posterior wings are 
gray; the abdominal space is black with the 
pink spot; the body and the legs are gray. 
Genitalia cT : The tegumen is not strongly 
developed and has a narrow and thin uncus, 
first turned upward, then downward; the 
apex is sharp, the dorsal part of the uncus is 
clothed with bristles; the vinculum is rather 
broad, lengthened toward the frons but does 
not form a real saccus; the anal tube has a 
well-developed scaphium; the valvae (Fig. 
2a) are subrectangular with a short expan- 
sion in the area of the external ventral angle; 
in the middle of the internal surface is a 
narrow process; the juxta is well developed 
and the penis is short, in part membranous 
in its apical region. 
Genitalia 9 : The lobes of the oviporus 
are almost square; the posterior apophyses 
are normal; the eighth urite is entirely sclero- 
tized, showing a differentiated plate in the 
middle ventral area above the ostium bursae; 
this, although not specialized, is clearly in-

dicated; the ductus bursae is highly sclero- 
tized in the part connected with the ostium 
bursae; the bursa copulatrix is large, with 
small sclerotized marks (Fig. 2b).
