DIONE MONETA, HUBN. AND D. GLYCERA, FELD. 277 
Colombia, Ecuador and Peru, but he wrongly assigns Costa Rican 
specimens (which belong to poeyti) to butleri, and gives the 
locality of true moneta as Bolivia and Upper Amazon, whereas 
specimens from those districts are in fact referable to butlert or 
are intergrades. 
Seitz (1918), who seems doubtful about the distinctness of 
D. moneta and D. glycera, has figured poeyit under the name of 
butlert, and refers to poeyt (sie!) as a Cuban form in which the 
fore wings have the discal area lighter! This is altogether 
wrong, for I can find no record of Cuban specimens of moneta and 
much doubt whether the species occurs in that island. 
It is remarkable that none of the above-mentioned authors 
seem to have known of the existence of D. moneta in the area 
which the typical form actually does inhabit, namely, Northern 
Argentina and the extreme south of Brazil. This typical form 
differs from the other two races in the much lighter colouring of 
the upper surface, the base of the fore wings being scarcely or 
not at all darker than the discal area and the discal black spots 
being vestigial or absent. In January, 1920, I met with it 
sparingly near Santa Maria in Rio Grande do Sul, and in the 
following month I found it very abundant at Salta in N.W. 
Argentina at elevations of from 2000 to 3500 ft. Many of 
these specimens agree absolutely with Hubner’s figure, thus 
disposing of the idea that the latter was intended to represent 
D. glycera, but a few of the Salta examples are transitions 
towards the form butleri, although never so dark as those from 
Colombia and Ecuador. The butterflies have a flight similar to 
that of the larger Argynnis, but frequent flowers by the roadside 
and damp places on the ground; they are never found in the 
dense forest. In Colombia I have taken the form butlert at an 
elevation of 4500 ft , and rarely near Caracas at 3500 ft., but in 
both countries it probably occurs much higher. In Central 
America the form pryii occurs, according to Godman and Salvin, 
from near sea-level up to 8000 ft., but personally I have never 
met with it below 3000 ft.; on the other hand I once took 
several examples on the Volcano of Cartago in Costa Rica at 
nearly 10,000 ft. 
D. glycera is a very similar but smaller species of much more 
restricted range, occurring only in Venezuela, Colombia, Ecuador 
and Peru. The type was from Venezuela, and Stichel has 
recently separated the Colombian race under the name of 
Gnophota, but the characters upon which this is founded are so 
slight that it is doubtful whether the name can be maintained. 
Specimens from Ecuador and Peru are in any case similar to 
those from Colombia. The species is found as low as 3000 ft. 
in Western Ecuador (Huigra), and as high as 8000 ft. above 
Medellin in Colombia, flying at the same time of year as moneta 
var. butleri. Whether D. glycera is fully distinet from D. moneta
