primaries beneath; the white spot near the middle of the inner margin of the 
primaries is smaller and rounder in the former than in the latter. The range of these 
two near allies overlaps to a considerable extent; but E. ofella has a more southern 
extension and does not pass beyond Guatemala.

E. myic similis, sed alis anticis paulo magis productis, macula apud marginem internum majore et subtus anticis

The differences between this species and E. myia are given above under that species. 
In its wide range some slight variation occurs between individuals from extreme points. 
Southern examples, especially those from Venezuela, are whiter than is usual in specimens 
from Guatemala ; but the difference is hardly of specific value. The type described and 
figured by Hewitson came from Colombia and formed part of Mr. Birchall’s collection 1.

As Mr. Bates pointed out’, this species has usually been confounded with EZ. nauplia 
(Linn.), with which it associates in the valley of the Amazons and throughout a large 
portion of its range. Mr. Bates adds that he took both sexes of each species in about 
equal numbers in the Amazons valley, and found the differences between the two 
forms quite constant. Both species are figured on plate 46 of Clerk’s ‘Icones 
Insectorum:’ figg. 1, 2 represent the true E. nauplia, whilst figg. 3, 4 represent the 
present species. 
In Central America £. clara is alone found, the insect called E. nauplia by Messrs. 
Butler and Druce* belonging here. It has a wide range in the hotter districts from 
Guatemala southwards.
