128 Sir George IF’. Hampson on the 
through Scoparia with vein 5 stalked or from a point 
with 4, Mestolobes with vein 3 absent, J'etraprosopus with 
porrect tufts of hair on the palpal joints, Helipsiodes 
with the median nervure of hindwing loosely pectinated, 
and Micraglossa with the palpi upturned. 
Of the value of the Hydrocumpine as a group there 
is considerably more doubt; they are primarily dis- 
tinguished from the Pyraustine by vein 10 of the fore- 
wing being stalked with 8, 9, but this character breaks 
down in many individuals of several species of Nymphila, 
Oligostigma, etc., not in the genera most closely allied 
to the early genera of Pyraustine, but in the more 
specialized genera where one would have expected the 
character to have become fixed; these are to be dis- 
tinguished by their long maxillary palpi and long upturned 
palpi with acuminate 3rd joint, except from a few Pyraus- 
tine genera such.as Sufetula, Massepha, and Homophysa, 
from which they are to be separated by their facies only. 
It may in consequence be contended that it would be 
more natural to distribute the Hydrocampinx among the 
Pyraustine, as Mr. Meyrick does, in accordance with the 
forms of their palpi, placing the group of genera allied to 
Nymphula near Sufetula and Homophysa, the group 
allied to Coptobasis and Tatobotys near Sylepta and 
Nacoleia, and Stenia, Diathrausta, Hurrhypara, ete., in 
the true Pyrausta group; but the fact that the genera 
Talanga, Daulia, and Parthenodes, which are undoubtedly 
closely allied to the Nymphula group, have short porrect 
palpi, and appear to form the transition between the 
porrect and upturned palpi groups, seems to make it 
advisable to retain the group, at all events pending 
further evidence, and not to merge it in the already 
very inconveniently large subfamily Pyraustine. 
The genus Cenoloba from Australia is extremely 
aberrant and not at all closely allied to any other 
Pyrale, though the well-developed maxillary palpi and 
the neuration of the hindwing show clearly that it 
belongs to the family; vein 5 of the hindwings from the 
middle of the discocellulars is a very generalized cha- 
racter, only found elsewhere in the Pyralide in Simx- 
thistis, Tineodes, and Oxychirotis, the first Indian, the 
two latter also Australian, and all three coming among 
the very early Pyraustine; the palpi are like those of 
Tineodes or a Crambus, whilst the fore and hindwings are
