My study of the bibliography has been very superficial and 
my material too scanty for a satisfactory revision of these little 
known species. Lyccena ludicra Weymer 1890 ( op . cit. : 122, 
“Tacora, Bolivia,” pi. 4, fig. 3 5) may be a form of Itylos moza , 
or an allied species, with well developed cyanic overlay, and 
Itylos grata Kohler 1934 (Rev. Soc. ent. Argentina 6 : 38-39 
“Las Lajas, Argentina,” text fig. [poor phot.] 5 ) is apparently 
close to pads Weymer. Cupido vapa Staudinger 1894 (Iris 7 
: 79, “Huallatani; Cocapata, Bolivia”; Lyccena vapa , ibid. pi. 
2, fig. 4 5 ) may turn out to belong to Itylos , and the same may 
be said of Lyccena martha Dognin 1887 (Le Naturaliste 9 : 190, 
“Loja, Ecuador”), which, judging by the woodcut (l.c. fig. 
5 5 $) combines Hemiargus and Itylos wing characters and 
very possibly is a form of koa (some specimens of which have 
a well formed, “black,” scintillated praeterminal mark in Cu^ 
with strongly developed ornamentation of the catochrysopoid 
type. 
Generic Description 
A very holarctic looking genus. TEdeagus acuminate, slightly 
incurved, in structure and shape closely allied to Icaricia , Aricia, 
and Lycceides. Suprazonal portion subequal to the subzonal 
one ; suprazonal sheath in ventral view rather narrow above the 
zone, then slightly broadening, then tapering to a sharp point, 
and (in side view) laterally enveloping the vesica only immedi- 
ately above the zone, then gradually turning into a strictly 
ventral shield. Vesical opening on the dorsal side beginning 
immediately above the zone, vesica plain, weakly convex, about 
as long as the subzonal sheath. Alulae small. Furca well devel- 
oped. Sagum absent. Falx resembling an enlarged edition of
