the antenne than at the vertex. Pubescence of thorax and 
abdomen rather finer than in A7rt/pes, while on thorax, abdo- 
men, and legs the pubescence is brighter yellow, almost 
golden, not dull yellowish white as in hertipes. Femora 
yellowish on the basal half or more. All tibia conspicuously 
yellowish in the middle, basal and apical sixths black. Tarsi 
entirely black (as in S. hirtipes). 
SWITZERLAND: Canton du Valais—Gruben, 1847 wm., 
vill. 1920, and Lac de Champex, 1465 m., ix. 1920 (Prof. 
Galli- Valerio). The collector writes: ‘* They were in swarms 
and very unpleasant, entering into the nose, mouth, and eyes, 
but I was never bitten.” 
‘Type and eight other females presented to the British 
Museum by the collector; others returned to him. ‘The 
other European species, which probably, though not certainly, 
belong to’ the subgenus (rufum, Mg., ferrugineum, Wahlg., 
and pallipes, Fries), are quite distinct; macropyga, Lundst., 
is no doubt a Prosimulium, but is known only in the male 
sex, and may not be distinct from hértipes. None of these 
four species are represented in the British Museum collection, 
Stmulium (Prosimulium) fulvipes, sp. ., 2. 
Closely related to S. (P.) hirtipes, Fries, and S. (P.) gallia, 
sp. u., differing as follows:—Front wider than in hirtipes, 
but narrower than in gall, being about one and a half times 
as broad at the vertex (that is, between the angles of the eyes) 
as it is at the level of the antenne (in Scottish examples of 
hirtipes it is almost twice as broad between the angles of the 
eyes as it isjust above the antennee). Pubescence of thorax 
rather yellower than in Airé?pes, but not so distinetly golden 
nor so dense as in gallit. Scutellum reddish, Femora and 
tibia almost entirely yellowish, only the bases and tips of 
the latter dark ; bases of metatarsi also distinctly yellowish, 
at least on four front legs; second joint of hind tarsi also 
more or less yellowish at the base. Costal veins paler than 
in hirtipes or gall. 
BULGARIA: Mt. Rila, 2000 m., 2. ix. 1906 (Prof. Schisch- 
kof ). 
Type and two other females presented to the British 
Museum by the collector. 
A female trom Thues les Bains, Pyr. Or., 8. France, 
26. vi. 1900 (Lord Walsingham), may be conspecific, but 
lacks the pale bases to the anterior metatarsi. This may 
possibly be Meigen’s 8. rujipes, which, however, is described 
as having a reddish-brown abdomen.
