﻿AFKICAN CULICIDAE, OTHER THAN ANOPHELES. 19 



9. 0. faseipalpis, sp. n. 



Q . Head clothed mainly with loosely applied flat scales, a few narrow curved 

 and some upright forked on the nape, pale yellow ; the flat scales are mostly pale 

 yellow, but there are a few black ones in front, and a pair of sublateral triangular 

 patches of the same colour. Antennae and clypeus black, first antennal joint 

 with small whitish scales on the inside, clypeus bare. Palpi black-scaled, with a 

 median white band ; fully one-fourth as long as the proboscis, rather thin. 

 Proboscis black-scaled, a few white scales in the middle of its upper surface. 

 Thorax black, clothed above with black and pale yellow narrow curved scales ; 

 the distribution of colour will best be understood by a glance at the figure. 

 Pleurae with patches of flat white scales. Scutellum with flat white scales on the 

 median lobe. Wings with the veins clothed with black scales, a few white ones at 

 the extreme base of the costa ; first fork-cell a little longer than second, its stem 

 rather more than half its length. Auxiliary vein terminating at the costa just 

 before base of first fork-cell. Legs black, femora whitish on the basal two-thirds, 

 and at the extreme tip ; all the tarsal joints with white basal bands, that on the 

 metatarsus the narrowest. Claws of hind legs simple. Abdomen black-scaled, the 

 segments with narrow basal white bands, which expand very slightly laterally 

 and in the middle, on all eight segments. Venter black, with basal white bands 

 on the first five segments. Ovipositor not visible. Length 4 mm., without 

 proboscis. 



Type in the British Museum ; presented by the Entomological Research 

 Committee. 



Described from a single female, in perfect condition, bearing the label " Little 

 Ruaha River, South Usangu District, 3,500 ft., German E. Africa. 28. xi. 

 1910. S. A. Neave." 



Fig. 4. — Ochlerotatus fascipcdpis, sp. n. 



This species most resembles O. hirsutus, but is much darker and has banded 

 palpi and a flat-scaled scutellum. The thoracic adornment is very suggestive of 

 O. wettmani, 0. ornatus and O. lateralis, and perhaps the real relationships of the 

 insect are with those species. The three last-mentioned, with O. longipalpis, 

 form a distinct group, in which the eighth abdominal tergite in the female is 

 larger and broader than usual, and the cerci are minute or absent ; the male palpi 

 of O. lateralis and O. longipalpis are scarcely swollen. This group, therefore, 

 seems to connect Ochlerotatus with Stegomyia.
