130 Sir George F. Hampson ow the 
Elwes for the gift of the types described by Mr. Meyrick 
from the Malayan region; and Mr. Meyrick for much 
help with the Australian species, and I wish specially 
to acknowledge the help derived from his papers, which 
have cleared the whole groundwork of the classification 
of the Pyralide. 
As in my other papers on the Pyralidx, species of 
which the type is in the British Museum are marked with 
at; species I have examined, but which are not in the 
Museum, with a *; whilst species I have been unable to 
see, and the classification of which is doubtful, are enu- 
merated at the ends of the genera. When it is stated 
“Types in Coll. Rothschild and B. M.”, the type is in 
Mr. Rothschild’s Collection, a co-type in the British 
Museum. Of a large number of the species not in the 
Museum, which have never been figured, coloured draw- 
ings have been made from the types and pinned into 
their places in the collection, among others of the whole 
of the types of Pyralide in the Oxford Museum Collec- 
tion, for the loan of which I am indebted to Prof. 
Poulton. 
Subfamily Hyprocampina. 
Moths usually of very slender build, the legs very long. Pro- 
boscis present. Forewing with vein 7 from the cell; 10 stalked 
with 8,9, except in a few species of Nymphula and Oligostigma, 
and in a small percentage of specimens of other species in these 
genera, this character, though highly characteristic of the sub- 
family, not having become a very stable one in the subfamily ; 
these exceptions may be discriminated from the Pyraustine by their 
long maxillary palpi dilated at the extremity. Hindwing with the 
median nervure non-pectinate. 
The larve of some species of Nymphula feed on water-plants, 
and are fitted for a life below the surface of the water.
