SATYRINAE 
28 
show ocelli of varying size on the wings both above and beneath. These ocelli are often white pupiiy 
and usually dark ringed: they are variable in size and number even in the same species, and those 
nearest apex and tornus show a tendency to divide, when one of the ])air is usually larger than its fellow. 
At fii’st siglit many of the sj)eeies bear a supei'fieial resemblance to eacli other. 
A tendency toAvards melanism (an increase in the size and intensity of the dark markings of tlie wing) 
is noticeable in the butterflies of this subfamily. In illustration of I his, Ave have figtired melanic exampies 
of Heteronymjyha merope and lleteronympha philerope. 
We have only defined tAvo neAv genera, though upon the A'enation alone nearly ex’ery species of 
JJeteronyynplia might be separated. In the generic table Ave ha\*e used as a minor subdivision the relative 
lengths of vein 5 and A’ein (i of the foreAving. This difference in length is the result of the diseocellii- 
lars being directed toAvards the termen or toAvards the base. The generic definitions are based entirely 
upon Australian specimens.

Genus MYCALESIS Hubner. 
Verzoichniss bekannter Schmetterlinge, p. 55, 1816. 
Antennae about half tlie length of costa. Avith clubs long, gradual and slender. Eyes liairy. Fore- 
AAing AA'ith Aein 12, median A'ein and A’ein la. sAA’ollen at base: A'ein 10 from su})Costal before end of 
cell: vein () someAvhat shorter than vein 'y: cell about half length of Aving. HindAving Avith vein 3 and 
A’ein 4 arising A'ei*^' close together. The sexmarks of the male consist of a A'ariable patch of specialised 
scales set in a iiearly area on vein la of foreAving beneath, and a similar patch at base of vein 7 of 
hindAving above, Avhich is coA-ered by a pencil of long hairs lying along the subcostal A*ein. 
Type. Mycalesis erande Cramer, from Africa. 
This genus is found throughout the Tndo-Australian and Aethiopian Eeo’ions. Moore has split up 
the Tndo-Australian species into a large number of genera, but most of these are, Ave believe, onlv 
admissible as siibgenera. In Australia the genus is only found north of latitude 25°. The biitterflie=! 
aie all small and of AA'eak flight, and occur abundantlv in grassy clearings flying close to the yTOund. 
The arrangement of the ocelli of the hindwing beneath affords some beln in the determination "of the 
species.
