﻿34 F. W. EDWAEDS— A SYNOPSIS OF THE SPECIES OF 



the name of the African species. Although Culiciomyia does not seem to differ 

 structurally from Culex, it is perhaps worth while retaining it as a separate 

 genus, since the group can be fairly easily recognised on scale characters. It 

 should, however, be noticed that in Culex annulirostris (and C. somaliensis and 

 C. microannulatus, both perhaps forms of C. annulirostris) the male palpi have a 

 row of white translucent hairs in the same position as the similar scales of 

 Culiciomyia.

 (1901). 

 Culex fragilis, Ludl., J. N. Y. Ent. Soc. p. 142 (1903). 

 A specimen in the British Museum named Culex frag His is undoubtedly only 

 C. nebulosa. Hence this species, like B. luteolateralis, extends its range into the 

 Philippine Islands. 



Genus Eumelanomyia, Theo. 

 Mon. Cul. V, p. 240 (1910). 

 Resembles Culex in most essentials ; the male palpi are somewhat shorter than 

 the proboscis, of uniform thinness and almost devoid of long hairs ; there is a 

 large area of flat scales over the top of the head. From Culiciomyia this genus 

 can be distinguished by the shorter male palpi, which lack the characteristic row 

 of outstanding scales, and by the more extended flat-scaled area on the head.

A medium-sized blackish species, with small lateral, apical pale spots on the 

 abdominal segments, and a pale venter.

 1. M. (?) inconspicuosus, Theo. (Aedes), Entomologist, XLI, p. 109 (1908). 



This is a small brown mosquito, 3 mm. in length, and without close examina- 

 tion might be mistaken for a Uranotaenia or an Ligramia, but the proboscis is 

 not swollen at the tip, the fork-cells are longer, and the lateral vein-scales 

 narrow. 



The genus Micraedes was founded by Coquillett for a single North American 

 species, M. bisulcatus, which has the palpi one-third the length of the proboscis 

 in both sexes, and a tooth on one claw of the fore and mid legs of the male. 

 This African species does not quite agree with Coquillett's diagnosis, as the palpi 

 are barely one-sixth the length of the proboscis in both sexes, and all the claws 

 are simple (those on the fore and mid legs of the male being unequal) ; as, 

 however, the species fits better into Micraedes than any other genus, I have 

 included it here rather than create a new genus for it on very slight characters.
