216 RHOPALOCERA. 
Hewitson, who gave a figure of it in their ‘Genera of Diurnal Lepidoptera.’ We have 
never seen this specimen, nor any thing like it from Central America; but Monsieur C. 
Oberthiir, into whose hands Dr. Boisduval’s collection passed, tells us that the type still 
exists, and that the figure is a good representation of the insect, which he considers to 
belong to an excellent species. It is evidently closely allied to V. antiopa, and is said to 
inhabit Mexico. 
GRAPTA. 
Grapta, Kirby, Fauna Bor.-Am. iv. p. 292 (1837) ; Doubleday, Gen. Diurn. Lep. i. p. 195. 
This is another northern genus, found in both the Old and New Worlds, and entering 
our region only in Mexico, where two species have been discovered. 
The secondary male sexual organs in Grapta have the tegumen very feeble, but with 
lateral projections, one on each side, meeting in the middle line below the central spine 
the harpagones have the dorsal edge prolonged into a stout incurving spine. 
The palpi are hairy, and clothed anteriorly with densely matted scales; the terminal 
joint is about one third the middle joint, which is slightly swollen; the antenne have 
87 joints, whereof 11 form a moderate club, the last joint of which is blunt; the front 
legs of the male are slightly hairy, but clothed with densely matted scales; coxa=3 
femur-+trochanter ; tibia—femur; tarsus=} tibia; the claws of the other legs are 
strongly curved, the paronychia being also curved and the pulvillus well developed. 
The margins of the wings are very undulating, the costa of the primaries sinuated 
towards the base; the first and second subcostal branches are thrown off before the end 
of the cell, the third a short way beyond it; the upper discocellular is short and only 
half the middle. The costal nervure of the secondaries is much curved, the precostal 
being nearly at right angles to it. 
Grapta may be distinguishcd from Vanessa not only by the curvature of the costa 
and the crenulated margin in both wings, but by the palpi and front legs being clothed 
with large densely matted scales.

Hab. Mzxico 1, Oaxaca (Fenochio), Rio del Monte (coll. Staudinger). 
We have a single example of this species, obtained by Fenochio in the mountains of 
Oaxaca, and have seen others in the collection of Dr. Staudinger from Rio del Monte. 
The former agrees accurately with Doubleday and Hewitson’s figure in the ‘ Genera 
of Diurnal Lepidoptera.’ In its size and in the arrangement of the black spots of the
