the costa well developed as a long and strong 
arm, upturned, widened at its apex, strongly 
sclerotized, and well colored; the valvula and 
the sacculus are recognizable but the sac- 
culus is not distinct; the juxta is simple, in 
the shape of a lengthened plate; the penis 
(Fig. 3 b) is long, with the rostral extremity 
widened and neatly indicated, with the distal 
apex upturned almost at 90 degrees and in- 
clined toward the left side. 
Genitalia 9 : The lobes of the oviporus 
and the eighth urite are rather long but nar- 
row as compared with the great develop- 
ment of the seventh urite. The lobes of the 
oviporus, as well as of the eighth urite, are 
abundantly clothed with bristles. The tergite 
of the seventh segment is strongly developed 
and covers the whole genitalia. The sternite 
of the same segment is modified; beneath the 
ostium bursae are found two triangular plates 
with their tops turned caudad: these plates 
lie on each side of the middle line; the ductus 
bursae is completely sclerotized and strongly 
colored; the ostium bursae is clearly marked 
and well visible; the bursa copulatrix is mem- 
branous and abundantly ornamented with 
unsclerotized folds.

The proboscis is fully developed; the labial 
palpi are upturned, the second joint reaching 
the vertex of the head, the third joint being 
long and directed obliquely; the frons is 
smooth with a tuft of hairs; the male anten- 
nae are ciliated. The thorax has no crest. 
The venation is as described for the sub- 
family.

Wingspread 72—96 mm.; length of the 
anterior wings 37-42 mm. 
The head and the thorax are reddish brown 
tinted with gray; the abdomen is yellow with 
the anterior edge of the segments black. 
The anterior wings are reddish brown irro- 
rated with gray and black; the antemedial 
line is brown and is obliquely curved in the 
middle of the cell; the orbicular spot is small 
and greenish gray; at the apex of the cell the 
reniform spot is typically greenish gray with 
some small black spots; a brownish shadow 
is found beneath the costa; the postmedial 
line is brown, oblique; the submarginal line 
is whitish; the spaces between the ante- and 
postmedial lines and the subterminal line and 
the external margin are of a lighter shade of 
the background color. 
The posterior wings are yellow with a 
middle band and a submarginal black band 
from the costa to the anal fold. 
The underside of the wings is yellow; in 
the anterior wings, in the area of the inferior 
angle, there is an indefinite black spot; the 
legs are yellow with the tarsi gray.
