1945] Notes on Neotropical Plebejinoe 13 
line convex posteriorly and somewhat concave below its promi- 
nent anterior point. Uncus lobe very long, thicker and blunter 
than in Chilades , somewhat related to Plebejus , slightly ex- 
curved, just above one-half the length of the tegumen proper, 
twice broader than the forearm and more than five times as long 
as broad. Valve bearing a false resemblance in shape to Iolana 
Tutt ( Glaucopsy chinee ) ; in general proportions likewise resem- 
bling Parachilades ; in character of rostellum somewhat allied 
to Pseudothecla ; in basic structure truly allied to the next 
genus; very short, at its broadest (very distal) part about three- 
quarters as broad as long, shorter than the sedeagus, about 
sixteen times shorter than the length of the forewing (which is 
about 11 mm.) [the latter ratio being one-eighth in Freyeria 
(about 7 mm.) where, as in all Old World Plebejinoe , the valve 
is longer than the sedeagus], subtriangular, strongly expanding 
from its bluntly rounded base to form a buffalo hump; the 
process superior abruptly sloping from that point to evenly rise 
again at a point immediately below whence it projects distad 
as a slender, very slightly incurved, horn-like rostellum, in 
length just under one-sixth of the whole process. Stretch be- 
tween rostellum and mentum extensive and steep, lending the 
valve a gaping appearance, this effect being due not to any spe- 
cial feature of mentum or distal margin of valval membrane, 
but to the rudimentary or aborted (despite the horn-like free 
end) condition of the upper process which in all other Plebe- 
jinoe is long enough to allow the rostellum to rest on the mentum. 1 
Female: fibula well developed, about 0.16 long by as much 
broad, consisting of a triangular portion over an oppositedly 
directed cordate one. Papillae anales small, about 0.3 broad by 
0.2 long with comparatively very long (0.82) rods. 
Measurements (in mm.) : aedeagus 1, suprazonal portion 0.5, 
subzonal 0.5 with breadth (in lateral view) 0.11; penis 0.93. 
Furca 0.47. Sagum 0.33. Vertical/Horizontal extension of un- 
1 In situ the end of the processus superior of bornoi tends to be infolded, i.e., 
to overlay the ventral concavity of the valve as occurs also in Parachilades , 
Chilades , and Hemiargus (s.s .) . Another character of these valves (and also that 
of the next genus) which lack the regular bullula of other genera is the fact that 
under pressure the whole margin below the rostellum has a trick of bulging (pro- 
ducing as it were a second mentum), a circumstance which incidentally misled 
Bethune Baker (1913, Trans. Ent. Soc. London 1913: 201-204) in his rather con- 
fused attempt to separate what he called phiala Grum Grshimailo (of which he 
examined, at the best, a locotype or cotype — not the actual type as wrongly 
stated : 204) from the absolutely conspecific galba Lederer.
