Fauna, with descriptions of new species. By KENNETH

Puates V. & VI. 
THE discovery of a species of Oxyethira new to the 
British Islands, and the enquiries made in connection 
with its determination, have resulted in bringing before 
me a considerable mass of Hydroptilide, including 
species of much interest, several of which are quite new. 
Noteworthy amongst the material referred to is a large 
consignment, from the collection of Mr. McLachlan, of 
undetermined Hydroptilide, in which forms apparently 
belonging to the genus Hydroptila are most numerous, 
and comprise at least three which are undescribed. I 
now describe these, together with the British Oxyethira 
above alluded to, which has proved to be new; and I 
also take the opportunity to describe another new Oxye- 
thira, received from Dr. John Sahlberg, of Helsingfors. 
A few notes are added concerning points of interest in 
connection with previously-known species. 
In these notes I have endeavoured to follow the 
terminology used by Mr. McLachlan in describing the 
appendages of the male; but in such minute and densely 
hairy insects, the points of origin and true nature of 
these parts are not always easy to trace. I think, how- 
ever, that with the aid of the accompanying figures, 
drawn under the microscope with the camera lucida, 
there should be no erga: in understanding what is 
intended. 
Genus Hyproptina, Dalman. 
Hydroptila stellifera, n. sp. 
Antenne about 34-jointed in the male, fuscous; clothing of 
vertex yellowish white, the hairs on the face darker; palpi
