NEW NORTH-EASTERN SUMATRA BUTTERFLIES. 45 
This subgenus will comprise the following species :— 
Euthalia (Nora) kesava, Moore. ‘ 
discispilota, Moore. Probably one species. 
rangoonensis, Swinhoe. } 
ramada, Moore. 
decorata, Butler. 
a »  bipunctata, Vollenhoven. 
es! » _ salia, Moore. 
Ee »  erana, de Nicéville. 
i » (2) laverna, Butler. 
se »  lavernalis, de Nicéville. 
All these species I possess, except #. laverna and £. lavernalis. There are 
probably other described species which should also be included in the list 
which J have not seen. The subgenus is a very compact and natural one, all 
the species being closely allied. 
I give below a key to the subgenera which I would admit in the genus 
Huthalia, 'To my mind there is something peculiar and distinctive in all Luthalias, 
As far as is known, their transformations are similar, and in the field they have 
the same habits. ‘They have a bold flight, settle with wings both closed and 
open, the former more especially when alarmed. ‘They are particularly partial 
to the juices of over-ripe fruit. I deprecate as much the splitting up this genus 
into numerous genera as I do those of Danais, Huplea, Lethe, Mycalesis, Neptis, 
Charaxes, Papilio, and others, At the same time, for classificatory purposes, it is 
most convenient to institute subgenera for the various groups into which the 
above-named and other large genera can be divided. If these subgenera be 
raised to the rank of genera, at once all connection between them appears to be 
lost, a Dophia becomes as good a genus as an Huthalia, this being very far from 
the case, while Dophia, Huthalia and, say, Charazes are all genera of equal rank, 
which misrepresents the facts, as Oharares is entirely distinct from the other 
two, which latter are closely allied.
