Vol. IX, No. 1.] Diptera of the Lake of Tiberias. 51 
[V.8.] . 
10. Uranotaenia unguiculata, sp.n. o&. 
Head black scaled, a rim of bluish-white scales round the 
eyes and a patch of similar ones on the nape. Proboscis, palpi 
and antennae dark b 
Thorax dark bein, ere black towards the margins of 
the mesonotum ; a line of flat bluish-white scales extends from 
the wing-base forwards to the very front of the mesonotum, 
not, however, meeting its fellow; a similar line of scales, 
parallel with the first, extends across the pleurae and protho- 
racic lobes. Wings with dark brown scales, except for a short 
space at the base of the first longitudinal vein, where the 
scales are white. Lateral vein scales about three times as long 
as broad. Upper fork-cell rather narrower, but almost as long 
as lower. Halteres dark-brown, stem light brown. Legs dark- 
fied, except that the claws are much larger than usual and 
unequal ; they are not, however, so unequal as those on the 
mid legs, which are normal. 
Abdomen clothed with dark-brown scales above, except 
the — segment, which is white. Venter pale. 
Rema In two respects—the unusual front claws, and 
= prolongation of the upper of the two lines of bluish scales 
the fro the mesonotum—this species differs from all 
cae Oriental or Ethiopian species of the genus, and its 
mayeri ; the former however has banded hind tarsi and 
no pale line on the middle femora, and the latter has white at 
the base of — fifth (not first) vein, and has white markings 
on the abdom 
ecurrence. i Tiberios, 1g (type: in the Indian Museum, 
Calcutta).
