dark, subterminal line. In constantia only the extreme apex is white, 
the remaining part of the apical third is largely filled with fuscous 
and leaden-gray scales. The female genitalia of constantia show much 
more sculpturing and spining in the bursa copulatrix than is present 
in serena. No comparison of the male genitalia can be made because 
the male of constantia is unknown. 
Cochylis constantia, new species 
Fiaure 11; Puarse 4 (Fria. 8) 
Alar expanse 17 mm. 
Labial palpus fuscous, paler on inner surface of second segment. 
Antenna grayish fuscous; scape sordid white strongly suffused fuscous. 
Head fuscous. Thorax mottled fuscous and pale gray; posterior edge 
white; apex of tegula white. Forewing ground color sordid white; 
basal patch ill-defined, indicated mainly by fuscous and gray mottling; 
costa marked by gray spots and short bars; at middle of costa a 
subquadrate, gray blotch; on dorsal edge six small, fuscous spots; 
from mid-dorsum a large gray blotch extending into cell and super- 
imposed over it an outwardly oblique fuscous band; from tornus to 
termen at vein 5, thence obliquely to costa before apex, a gray suffusion 
mixed with fuscous at its middle; apex white with three small, grayish- 
fuscous spots at edge; cilia grayish fuscous mixed with cinerous. 
Hindwing sordid white contrastingly mottled with grayish fuscous. 
Foreleg ocherous white overlaid with fuscous on outer side; midleg 
ocherous white suffused with grayish fuscous; tibia with fuscous spot 
distally on outer side; tarsal segments narrowly edged whitish distally ; 
hindleg ocherous white with only slight suggestion of infuscation. 
Abdomen grayish fuscous. 
Female genitalia slide JFGC no. 11593. Ostium slitlike; anterior 
edge slightly concave. Antrum broadly sclerotized. Inception of 
ductus seminalis from slight depression in side of bursa copulatrix. 
Ductus bursae short, membranous. Bursa copulatrix membranous 
except for longitudinal sculpturing posteriorly and spiculate inner 
surface. Accessory bursa from juncture of ductus bursae and bursa 
copulatrix. Lamella antevaginalis membranous; lamella postvaginalis 
scobinate. 
Holotype: U.S. National Museum No. 69756. 
Type-locality: Peru, Cusco, Machu Picchu, 2700 m. 
Distribution: Peru. 
Described from the unique female holotype (6.11.1959, J. F. G. 
Clarke). 
Under the foregoing, serena, I have discussed the apparent rela- 
tionship of the two species, but much additional material will be 
required before a proper alignment can be made.
