﻿44 F. W. EDWARDS — A SYNOPSIS OF THE SPECIES OF 



Diptera by a genus of Egger's, and thus it is necessary to coin a new name. It 

 is with much pleasure that I name the genus after Dr. A. Ingram, who has done 

 such excellent work in breeding many African Culicidae, and is the first to have 

 reared any member of this genus from the larva. I take this opportunity of 

 redefining the genotype, making it Mimomyia malfeyti, Newstead, the species 

 which has been bred by Dr. Ingram. 



Most of the characters will be gathered from the table, but the following may 

 be added : Proboscis of male with the apical half much swollen, of female less 

 swollen and then only at the tip ; second segment of female antennae at least 

 twice as long as the third ; lateral vein-scales rather broad or very broad. In 

 the African species the male claws are all simple. 



Ingramia consists of small gnats resembling Uranotaenia in general appearance, 

 and also structurally, in having the proboscis swollen towards the tip. The genus 

 differs widely from Mimomyia in many respects, though it is curious to note that 

 in some species of the latter genus the second segment of the female antennae is 

 elongated. 



Table of the species. 



1. Anterior third of mesonotum pale ochreous, concolorous with the 



pleurae, the rest dark brown ... ... ... 1. circumtestacea. 



Mesonotum uniformly brown or dark brown ... ... ... ... 2. 



2. Bristles of thorax long, in three distinct rows, the median one 



double ; scales absent except for regular rows of minute ochreous 

 scales between the rows of bristles ... ... ... 2. malfeyti. 



Bristles of thorax shorter, not arranged in distinct rows ; scales 



uniformly distributed, though rather sparse, blackish ... ... 3. 



3. Darker species ; second joint of female antennae almost five times 



as long as third ; integument of thorax all dark... ... 3. nigra. 



Paler species ; second joint of female antennae hardly more than 

 three times as long as third ; three darker patches on thoracic 

 integument... ... ... ... ... ... 4. uniformis.

 Second joint of female antennae about five times as long as third. 



Sudan. 



2. I. malfeyti, Newstead (Mimomyia), Ann. Trop. Med. I, p. 29 (1907). 

 Easily distinguished by the peculiar arrangement of the vestiture of the thorax. 



Second joint of female antennae only twice as long as third. The male and 

 female recorded from the Congo by Theobald (Mon. Cul. IV, p. 582) as 

 M. uniformis are this species.

 A distinct row of rather strong black bristles on the pteropleurae. The other 

 three species have only weak, pale-coloured hairs in this position. 2". nigra also
