Hydroptilide belonging to tie Hurupean fauna. 79 
ment.’ As he has there indicated, S. atra, being so 
much larger than the other described species, this figure 
gives a better idea of the neuration of the genus than 
his earlier one. 
Two insects from Madeira (Haton) appear to belong 
here. The anal parts are much concealed in the hairs, 
and the figures given are from an example entirely 
denuded and mounted in balsam. ‘The true form of the 
part between the pieces which are produced into a spine 
at the apex, is a little uncertain.

MeLachlan’s drawing) ; fig. 1, apex of abdomen, from beneath

Genus OxyrEtuira, Haton. 
Oxyethira costalis, Curt.—It appears to me that the 
lower margin of the inferior appendages in this species 
does not run continuously to the incurved apex, but is 
angulated before the apex, as shown in Plate VI., fig. 1. 
There isa pair of down-turned hooks lying above the 
ventral plate, one of which is shown in fig. 2. 
Oxyethira ecornuta, n. sp. 
Antenne 33-jonted in the male (mutilated ?), fuscous ; clothing 
of head whitish yellow; palpi fuscous; legs dingy testaceous. 
Anterior wings brown, with whitish markings and darker fringes. 
The ventral plate in the male is large and usually much produced, 
. the excision in its outer margin being shallow but extensive; the 
lateral lobes of the plate when viewed directly from beneath are 
small, but well marked, inturned and blackened. The inferior 
appendages are very short and scarcely incurved. Above the 
ventral plate is a pair of black much downturned hooks. The penis 
is not exserted in the examples before me; its apex, as far as 
visible, seems to be more decidedly dilated than in O. costalis. 
Ventral lobe apparently as in that species. Expanse of male 
about 5 mm. 
Three males and one female from Teisko, Finland, 
received from Dr. John Sahlberg. 
A species very closely allied to O. costahs, Curt., yet 
sufficiently distinct. It differs in the form of the ventral 
plate, and of the hooks above the plate; also and 
especially in the absence of the black inturned tips 
which mark the inferior appendages of O, costalis. rom
