218 A Monograph of Culicidae. 
Observations.—A. single 2 of this very distinct mosquito was 
given me by Dr. Cropper, taken on a “ hill-side” in Palestine. It 
answers in every detail to Ficalbi’s Culex hortensis, except that 
the scales at the base of the antennae are white, not light blue, 
nor are the scales on the pleurae and bases of the legs bluish 
white, but white to grey. The species is so very marked that no 
mistake can, however, be made, the white apical abdominal 
banding and the white band on the palpi being very character- 
istic. The difference seen in the antennal scales, and those on 
the pleurae, may point to hortensis being distinct. 
Ficalbi says that hortensis does not attack man, nor enter 
habitations, but he believes subsists on the juices of plants. 
CULEX SERGENTII. n. sp. 
Thorax reddish-brown, with narrow-curved dull brown scales. 
Abdomen black, with narrow apical white bands and large 
white apical lateral patches continuous with the apical bands ; 
venter entirely white-scaled ; proboscis and palpi deep brown. 
Legs deep brown, unbanded, with small white knee spots, and 
grey base and venter to femora. Wings with rich brown 
scales. 
2. Head deep brown, covered densely with rather long 
narrow-curved creamy-white scales, deep, brown upright forked 
scales and small rather long flat scales laterally, with some large 
black bristles projecting forwards over the eyes; palpi short, 
black-sealed ; proboscis deep brown to black; antennae deep 
brown, basal joint and base of the second paler. 
Thorax reddish-brown to deep reddish-brown, covered with 
narrow-curved brown scales, almost yellow around the front of the 
mesonotum, and some slightly paler ones in front of the scu- 
tellum, two more or less distinct median parallel bare lines with 
a line of black bristles between ; prothoracic lobes with grey 
scales ; scutellum pale brown, with narrow-curved pallid scales, 
and six brown border-bristles to the mid lobe; metanotum 
chestnut-brown ; pleurae pale ochraceous, with three patches of 
white scales, one under the root of the wings. 
Abdomen black, covered with black scales, with violet 
reflections, each segment (except the first) with a narrow apical 
border of white scales which spreads out laterally to form large 
apical white lateral spots; basal segment blackish, with two 
median patches of black scales, and long pale deep brown and
