40 Psyche [March-June 
Cyclargus ; somewhat allied to Aricia but well formed, with a 
steeper and narrower shoulder. Forearm straight, tapering to 
a blunt point, falcal arch narrow, shoulder high and conical 
though not as high in relation to the falx as it is in Echinargus. 
Uncus lobe with Albulina affinities, larger than in all preceding 
groups considerably higher than the forearm. Structure of 
tegumen at its junction with the uncus more elaborate, than in 
the preceding genera, of a common holarctic type ( Albulina , 
Plebulina , etc.). Valve likewise representing the holarctic 
norm, longer than the aedeagus, with a well developed bullula. 
Rostellum, broader than in Aricia , serrated, exceeding the men- 
tum in length, differing from Paralycceides in the latter char- 
acter as well as in the receding margin of the comb, the sharp 
regular teeth of which are directed downward. 
Papillae anales with comparatively short rods. Henia well 
developed, with an oval fibula ( koa ) somewhat resembling 
Aricia. 
Itylos moza Staudinger 
(figs, moz, pi. 6, 7) 
One male investigated: prep. 606, “Bolivia” ex coll. Hunting- 
ton [ex coll. Staudinger-Bang Haas], Am. Mus. Nat. Hist., and 
one female: prep. 528 ( Lyccena babhru Weeks, holotype), “Sica- 
sica, Bolivia, l-X-1899,” ex coll. Weeks, Mus. Comp. Zool. 
HLdeagus 1 mm. long with the suprazonal portion slightly 
shorter (by about 0.1) than the subzonal one. Furca about 
equal in length to the penis. Forearm a third of the length of 
the aedeagus, about ten times as long as broad, thus rather thin; 
humerulus thick, about a third of the forearm in height, and 
rising to double of that at the shoulder ; uncus lobe very slightly 
excurved, as long as the suprazonal portion of the penis, less 
than a fourth of that broad, somewhat expanding above the 
level measured, then gradually tapering to a rather well accused 
point. Valve large, about one and a half times longer than the 
aedeagus when measured from the base to the end of the rostel- 
lum and less than half as broad as long, with the hump at about 
two thirds of the length of the upper process from the base of 
the valve. 
Measurements (in mm.) : aedeagus 1, suprazonal portion 0.44, 
subzonal 0.56 with breadth (lateral view) 0.11; penis 0.94. 
Furca 0.93. Vertical/Horizontal extension of uncus (ventral
