332 Mr. H. W. Bates on the Nymphaline 
spots lying lengthwise, instead of forming a double row of spots, and 
in the arcuated rufous stripe on the inner side of the central stripe 
being simple instead of consisting of two rufous lines. The fulvous 
spot of the fore wing differs in shape from that of H. [phicla, being 
curved outwards. In the only example I have before me it is followed 
by a small fulvous spot near the apex.

This fine species has the form and strength of thorax of an Apatura. 
I found it sparingly on the Upper Amazons, in sunny places in the 
forest.

A common insect in the forest on the Upper and Lower Amazons. 
I have seen specimens from New Granada which do not differ from 
Amazonian examples.

Banks of Lower Amazons, in thinned woods, in company with 
H, Cytherea. 
* Another allied form belonging to the Zphicla group of Heterochroa is the 
following :— 
Heterochroa Basiloides (Boisd. MS.). 
9. Expanse 2” 8”. Similar on the upper side to H. Iphicla. White belt 
less green in hue, and extending on the fore wing to the lower radial nervure, 
followed by a white spot lying between the lower and the upper radials. The 
fulyous spotis similar in shape to that of H. Zphicla, but it is not prolonged infe- 
riorly. Beneath, the fore wing does not differ from that of H. Iphicla, except 
in the extension of the white belt, and the absence of the dusky-brown streak 
between the white belt and the submarginal lines. The hind wing, Jeneath, differs 
from H. Iphicla and all the allied forms in having a small spot at the end of the 
cell, between the central rufous belt and the arcuated streak : both the arcuated 
streak and the spot are formed of dark rufous lines.
