transition from the one to the other. The much larger size, however, of the southern 
specimens, coupled with the more strongly pronounced markings of the undersurface, 
and also the absence of the continuous violet on the discal area of the secondaries, in 
addition to the greater faintness of the submarginal ochreous line in the primaries, 
enable one without difficulty to discriminate between the two forms. 
E. bubocula was described by Mr. Butler from specimens in Van Patten’s Costa-Rica 
collection, whence we have also received examples, as well as others from the State of 
Panama. None of these are females, and that sex is only known to us from a specimen 
in Dr. Staudinger’s collection. We hesitate to admit that the Mexican females in the 
British Museum, alluded to by Mr. Butler in his description, really belong here. If 
the locality given to them is correct, it is far more probable they will prove to be 
females of H. wsacus. Our figures are taken, the male from one of the types from 
Costa Rica, the female from the one in Dr. Staudinger’s collection already alluded to, 
and which came from the State of Panama. 
NAROPE. 
Narope, Westwood, Gen. Diurn. Lep. p. 348 (1851). 
Seven species have now been described of this peculiar genus, which, though not 
nearly allied to any of the foregoing genera, clearly belongs to the Brassoline, a position 
indicated for them by Prof. Westwood. As in Opsiphanes, the prediscoidal cell of the 
secondaries is large; but the terminal joint of the palpi is longer than usual in this 
subfamily. There is a tuft of hair on the underside of the primaries above the middle 
of the submedian nervure, and a denuded patch to correspond on the upperside of the 
secondaries near the costa. The tegumen of the male (in WN. cyllastros) has a pair of 
peculiar short spurs, one on each side of the ventral surface, directed outwards; the 
harpagones have a simple dorsal edge, with a strong tooth near the extremity and 
another at the end. | 
Only one of the seven species is found in Central America; the rest are widely 
dispersed over South America, being found in Ecuador, Peru, Bolivia, and Brazil. 
None are as yet known from Guiana, though one is said to have been taken at Para. 
From what is said below it is probable that all the species are nocturnal in their 
habits; and as the underside of the wings has the coloration of a dead leaf, when at rest 
during the day with wings closed they must be very difficult indeed to detect. Hence 
their great scarcity in collections.
