﻿AFRICAN CULICIDAE, OTHER THAN ANOrHELES. 49 



2. C. pallidipes, Theo., Ann. Mag. Nat. Hist. (8) VII, p. 399 (1911). 

 Legs all pale ; wings unspotted ; thorax dark above. 

 Uganda. 



Sub-family 3. DIXINAE. 



Whole insect, notably the antennae (in both sexes) and the wings, almost bare ; 

 head and thorax as in Chaoborinae ; neuration of the Culicid type, but 

 differing in some details, principally in the course of the second vein ; in the male 

 the claws of the fore and mid legs are larger than those on the hind legs, and 

 bear several long, fine teeth on the under side ; in the female the claws are all 

 equal and simple. 



That JDixa is related to the Culicidae is now well recognised : Williston 

 favours its inclusion in the family, making three sub-families of Culicidae — as 

 here ; Dyar would group Dixa with Chaoborus and its allies into a separate 

 family. The inclusion of Dixa with the Culicidae is supported by (1) the 

 structure and habits of the larvae and pupae ; these, according to Knab, are 

 subject to much variation in Dixa, but are essentially similar to what is found in 

 the Chaoborinae ; (2) the neuration of the adults, which is of a form found 

 only in Dixa and the Culicidae ; (3) the structure of the adult antennae, with 

 one globular basal joint, common to Culicidae, Dixa, and Chironomidae, 

 but never seen in the Tipulid series ; (4) the occurrence of more or less interme- 

 diate forms between the three sub-families, such as Ramcia and Mochlonyx ; 

 (5) the differentiation in the claws — in the Tipulid series, so far as I have seen, 

 the claws are all alike. 



Genus Dixa, Mg. 

 Syst. Beschr. I, p. 216 (1818). 

 Two specimens of Dixa from Morocco are in the British Museum collection, 

 collected by Major P. Fowler, R.A.M.C., in 1909. These I have provisionally 

 determined as follows : 



1. D. maculata, Mg., Syst. Beschr. I, p. 219 (1818). 



Cross-veins much darkened, faint clouds on the wings ; thorax blackish ; legs 

 yellowish ; femora and tibiae blackish at tip, tip of hind tibiae somewhat swollen. 



2. D. aestivalis, Mg., Syst. Beschr. I, p. 218 (1818). 

 Wings clear ; thorax reddish ; legs all yellowish brown.
