Dec.. i8 9 8 ] . DYAR : O.V SOUTH AMERICAN MOTHS. 
type has two pair of spurs. The male is needed to place this genus finally ; compare 
section C. 
Type anticlea Druce 9 . Only the female is known and Mr. 
Schaus specimen is one of this sex. Consequently the male antennae 
are unknown. 
Genus Semyra Walker. 
i8 55 —Semyra Walker, Cat. Brit. Mus. V, 1130. 
1878— Eulimacodes Moschler, Verh. Zool.-Bot. Ges. XXVII, 672. 
Type coarctata Walk. The type species is before me ; also Mr. 
Schaus’ type specimen of Eulimacodes mdschleri , which is simply the 
female of coa)data Walk. S. distincta Moschl., with the same struc¬ 
ture and pattern, but larger and V. bella H.-S. are also before me. 
S. cardia Schaus begins to depart a little from the generic type. The 
palpi are a little shorter, not quite attaining the vertex, about as in 
Pt ostermdia Saalm., with which this species might be confounded in a 
synoptic table, though the markings are as in Semyra. 
Genus Prostern id ia Saalm. 
1884— Prosterniaia Saalmuller, Lep. Madagascar, I, 208. 
Type metallic a Saalm. I have not seen this type, but from the 
characters given, place in the genus provisionally P. elcea Druce 
(. Perola elcea D.), which is before me. 
* * Veins 2 and 3 of fore wings stalked. 
Genus A my dona Walk. 
1 8 5 5 —A mydon a Walker, Cat. Brit. Mus. V, 1110. 
Type subpunctata Walk. Mr. Schaus has kindly given me Perola 
dora Druce, which he thinks is the same as subpunctata Walk. The 
forks of discal vein form a right angle, or a trifle less; open. Con¬ 
generic are A. sucia Schaus (Perola sucia Sch.) and A. platona Schaus. 
A my dona sericea Schaus. 
This does not belong here, but I cannot place it, as the hind legs 
are gone. It is a curiously contradictory form, the male antennse 
being distinctly pectinated to the tip, though decreasing rapidly on 
terminal half, while the fork of discal vein is long and closed by a 
cross-vein. The palpi are upturned above vertex, third joint long 
and slender; head rather prominent. Venation normal, vein 1 with 
many small veinlets toward the margin, but no distinct branch ; veins 
2 and 3 widely separate, 7 to 9 stalked, 11 oblique ; hind wings with
