﻿AFRICAN CULICIDAE, OTHER THAN ANOPHELES. 37 



in Dr. Ingram's series bred from the same lot of larvae one specimen has a 

 banded abdomen, the rest showing only the lateral spots to a variable extent. 

 Usually the second joint of the female antennae is 2-£ times as long as the third 

 (31. hispida, type), but in some specimens quite three times as long (M. palustris, 

 type). The mesonotum is usually clothed with blackish brown scales and black 

 bristles, but the bristles are sometimes yellow and the dark scales seem replace- 

 able by yellowish ones. The metanotum may be all yellowish, or w r ith a dark 

 line down the middle (M. hispida, type), or entirely dark (M. palustris, type).

 On comparing the types of B. mimomyiaformis and M. pincema I find them to 

 be the same. The former has only the last 2^ joints of the hind tarsi pale, and 

 the pale spots on the tarsal articulations are present though faint. 



Second joint of female antennae 1^ times the length of the third, and rather 

 swollen.

I rather strongly suspect that this is really the same as the last species ; in any 

 case the claws are probably not " all equal and simple." One specimen in 

 Dr. Ingram's series of 31. hispida shows the c? palpi bent exactly as figured by 

 Theobald (First Rept. Welle. Lab. p. 83, where the species was not named), and 

 this condition is evidently only due to shrinkage.

This genus is quite an easy one to recognise. The most marked feature is 

 found in the short fork-cells, the first being slightly or considerably shorter than 

 the second. The head is always flat-scaled, and also the scutellum ; the proboscis 

 is slightly swollen at the tip in the female, distinctly so in the male ; the middle 

 femora are swollen near the base (but this is the case in many other mosqnitos) 

 The species are all small (2-3 mm. in length) and frequently have blue markings on
