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



under Mimomyia, while the new genus Ingramia has had to be erected for 

 those species which were formerly included with M. splendens in Mimomyia. 

 To the characters already given (Bull. Ent. Res. II, p. 244, under Ludloioia) 

 may be added the structure of the eighth abdominal tergite in the female. 

 This is narrower and more pointed than in Culex, though not nearly so narrow as 

 in Ochlerotatus, and is of uniform shape throughout the genus (see fig. 1, C). The 

 basal segment of the female antennae is hairy on the inside ; the second 

 segment is variable in length, but always longer than the third. 



In my previous paper (Bull. Ent. Res., Oct. 1911), reference to Ludlowia 

 sudanensis, Theo., was accidentally omitted ; it was described from a single male 

 mounted in balsam, which is said to be, but is not, in the British Museum 

 collection. As the ungues are described as " apparently all equal and simple," 

 its location in this genus must be regarded as doubtful until more material is 

 obtained. Dr. Ingram has performed the remarkable feat of breeding all the 

 African species, except the doubtful M. sudanensis. None of the larvae were 

 previously known. 



A fresh table of the species is given.

1. M. splendens, Theo., Mon. Cul. Ill, p. 304 (1903). 



This is one of the most striking and beautiful of all the African Culicidae ; 

 the brilliant green scales contrast strongly with the shiny black integument of 

 the thorax and make it an extremely well-marked species. The legs are mainly 

 golden yellow, but bear numerous purple scales, especially at the tips of the 

 femora, and the apical fourth of the hind tibiae is conspicuously black and some- 

 what swollen. There are traces of basal pale bands on some of the joints of the 

 tarsi, which are mainly brownish. Length 3 mm., without the proboscis. Second 

 joint of female antennae 1^- times as long as third. 



Uganda ; Sudan ; Gold Coast. 



2. M. hispida, Theo. (ffispidimyia), Mon. Cul. V, p. 245 (1910).

Megaculex palustris, Theo., Novae Culicidae, I, p. 13 (1911). 



This is a variable species, and it is possible that there may be two or more 



included under the same name, but I do not think so. The abdomen may be all 



purple, entirely unhanded, or with distinct basal lateral spots, or with entire basal 



yellow bands. That these are not specific differences is shown by the fact that
