TYPES OF LEPIDOPTERA. 
synonyms, most of the species having been previously named by 
Walker himself. 1 here remain seventeen names which must, I 
think, be adopted. Most of these have been since described by 
other authors, who had not the opportunity of examining Walker’s 
types. Of the four generic names proposed, none are valid. 
I should not have been able to obtain results so complete if it 
had not been for the generous assistance of Mr. J. A. Kershaw and 
Mr. Geo. Lyell. The latter went through the types before my 
arrival, and left me a box of examples from his own collection, which 
he had compared and identified with them. The former supple- 
mented these with other examples from the Museum collection. 
Having satisfied myself of the correctness of the identifications, 
and in some instances this required special care, I was able to study 
the loaned examples at leisure after my return to Brisbane. 
My detailed results are as follow : — 
1. Eterusia auroatra. — The type is unfortunately missing. 
The description applies to some species of unusually 
distinct appearance, and should be recognisable, but 
at present I cannot identify it with any Australian 
species known to me. 
2. Eutane partita.— This is a good species correctly identified 
by Sir Geo. Hampson, and described as Thallarcha 
partita (Cat. Lep. Phal. II., p. 503). There are 
several allied and very similar species ; this one is 
best distinguished by its deep orange-ochreous g round - 
colour, and by a fuscous spot in cilia of hind wings 
below middle. It appears to be very rare in collec- 
tions ; a specimen lent me from the National Museum 
bears the locality label Spring Yale, Victoria. I have 
taken a series, which T refer to this species, at Glen 
Innes, New South Wales, in October. 
3. Caslula binotata = Castulo doubledayi, Newm. = Cluaca 
rubricosta, Wlk. The type of binotata is a variety 
occasionally met with in which the termen and cilia 
of hind wings are ochreous, with a narrow dark-fuscous 
subterminal line. 
4. Orqyia semifusca is, I think, a good species, but cannot 
be referred to this genus. The $ agrees structurally 
with Porthesia, but Mr. Kershaw has lent me a ? from 
the National Museum which strikingly resembles a 
$ Orqyia. I propose to make this species the type of 
a new genus Ocybola, and both genus and species will 
be described below. 
5. Team ludipmnis is a synonym of Oenmmda boMuvalii, 
Newm $ ■ This species is sexually dimorphic.
