PERIDROMIA. 2738 
found in South-western Texas. We have specimens from Mexico and from various 
points in Central and South America down to Rio Grande in Brazil. The species, 
however, appears to be absent from Guiana and the valley of the Amazons. Its range 
in altitude in Guatemala does not exceed 3000 feet. 
c. Underside of secondaries pure grey, or slightly tinged with fulvous.

This widely spread South-American species is only found within our limits in the 
State of Panama, its place being taken in Costa Rica and elsewhere in Central America 
by the very nearly allied form A. guatemalena, from which it differs in having the 
secondaries beneath pure grey without any admixture of buff. In the Amazonian 
region Mr. Bates tells us it is the commonest species of the genus, being found in spaces 
in the forest where there is no underwood, or in plantations, settling on the trunks of 
trees 3.

Mr. Bates separated this form from P. feronia}. The differences, he says, are in the 
belt of dingy white spots of the fore wing, which consists of much more elongate spots 
giving a different aspect to the insect. The submarginal ocelli are very different from 
those of P. feronta. In the fore wing they have much larger round pupils (of a dingy 
grey instead of a white colour) and narrower black irides ; in the hind wing they have 
also large suboval dingy pupils encircled by three concentric rings, two narrow and grey,
