Explanation of Plate 1 
All figures X 18° A- 2 
1. ^deagus of Agrodiostus ( = Lysandra) cormion Nabokov (? hybrid between 
Agrodicetus coridon Poda and Meleageria meleager Esper), paratype, “Moulinet, 
Alpes Maritimes [S. France], 20-VII-1938 leg. V. Nabokov,” Am. Mus. Nat. 
Hist., in dorsal view. 
2. ^Edeagus (generalised Hemiargus s.l. etc.) in lateral view; 
3. Plain falx ( Lycceides ) ; 4 Humped falx ( Hemiargus etc.) ; 
5. Angulate falx ( Agrodicetus cormion , same specimen as 1). 
1,2. Measurements of aedeagus (= penis -f- sheathing) : d. distal point (often 
notched) of suprazonal sheath shielding vesica ventrally (projecting from under 
the vesica in fig. 1 as seen from the dorsal side of the organ) ; It. lateral edges of 
ventral part of suprazonal sheath (when fully developed these enfolding edges 
just reach the dorsal side of the organ and in dorsal view appear to line the 
vesica laterally as in Agrodicetus etc.) ; o. point at which the suprazonal sheath 
opens on the dorsal side (this point coincides with the zone in several genera, 
e.g. Agrodicetus ) ; c. Chapman’s process: a not unfrequently occurring spine-like 
or filament-like prolongation (of the dorsal lining of the sheath) running along 
the vesica, v. vesica (exposed distal portion of penis proper) studded with 
cornuti (minute hook-like or spine-like structures not represented in a number 
of genera) ; e. everted frothy membrane of vesica in erection; z. zone (level at 
which the organ is attached to the genital cavity) ; aa. alulae (out-turned flaps 
of subzonal sheath) ; p. base of penis enclosed in subzonal sheath; tt. proximal 
tabs of subzonal sheath. 
dt. length of aedeagus; dz. length of suprazonal sheath ventrally; oz. length of 
suprazonal sheath dorsally (excluding Chapman’s process) ; do. length of vesical 
opening on the dorsal side; zt. length of subzonal sheath with breadth measured 
at w in lateral view; vp. length of penis proper. 
3,4,5. Right uncus lobe with falx in flat ventral view; FHBUSA- falx, LUB- 
uncus lobe. 
F- point of forearm; H- point of elbow; B- basal point of humerulus; U- pos- 
terior point of shoulder proper; S- summit of shoulder; u- anterior point of 
shoulder; A- apex of (proximally directed) falcal arch; L- distal point of uncus 
lobe. 
1 persephatta Alpheraky which Stempffer (followed by Forster) makes con- 
generic with semiargus (apparently on the strength of a casual note in Chapman) 
belongs to another subfamily (Glaucopsychince ) .
