in a large rock pool in the Wadi Hof, some twelve 
kilometres South-east of Iielouan, at an altitude of 
about 200 metres. Three weeks later this pool was dry 
(and has remained so until the time of writing, —- 
November i 3 th, 1924.) and a search for aestivating 
adults was unsuccessful. It is possible, — but I think 
very unlikely — that the dry season is passed by this 
and other desert mosquitos in the egg stage. 
Gutex (Neoculex) deserticola, n.sp. 
Male : 
Vertex and occiput brownish testaceous, clothed 
with almost white narrow flat-lying scales, and pale 
brown upright capitate ones. Torus yellow, darker on 
the inner side, with a single row of about eight greyish 
white scales on the upper surface. Intermediate joints 
of the antennae whitish, with Mack rings at the in¬ 
sertions of the whorls of long greyish hairs, the last 
two joints brown with short pale hairs. Olvpeus 
yellow like the tori, proboscis brownish yellow, the 
apical third somewhat dilated, and appearing rather 
darker. Eyes in life bright emerald green. Palpi with 
the long joint similar to the proboscis, with some 
dark scales neare the middle and towards the apex, the 
last two joints dark brown above, rather paler be¬ 
neath, with abundant but not very long almost black 
hairs. The palpi are longer than the proboscis by 
about the length of the last joint.

central stripe, and somewhat browner at the sides be¬ 
hind. Scales straw-coloured, slightly paler at the sides 
in front, and in front of the scutellum.
