Distribidion. — S. Spain {Macdonald) ; Algeria {Sergcnt) ; S. Tunis (Tamerza, 

 Dr. M. Langeron). Does not appear to occur in Egypt or Palestine.

18. Anopheles (Myzomyia) turkhudi var. persicus, nov. 



The type male of A. tnrkhndi has no scales on the scutum, and has distinct 

 leaflets on the aedoeagus. The same is true of all specimens I have seen from the 

 Punjab, but a number sent me by Christophers from East Persia show distinct scales 

 on the scutum, and are in fact indistinguishable externally from A. multicolor. 

 They can hardly be that species, however, since the male aedoeagus bears distinct 

 leaflets, as in A. turkhudi and A. hispaniola. Provisionally, therefore, I regard them 

 as representing a distinct variety of A. turkhudi, which inhabits adjacent areas in 

 the Punjab. The real relationships of all these forms can only be determined by a 

 close study of their habits, early stages and distribution, and the early stages of this 

 Persian form are not yet recorded.

The adult does not differ appreciably from A. hispaniola and A. turkhudi except 

 in having scales on the mesonotum (these scales, however, varying in number, width, 

 and distinctness), and in the entire lack of leaflets on the male aedoeagus. A. 

 superpictus has a similar thoracic ornamentation, but can easily be distinguished 

 by its white-tipped palpi. Egyptian specimens commonly have the wings more 

 extensively dark than those from Algeria, but, on the other hand, it is almost certain 

 that Donitz's A. impunctus, described from an abnormally pale specimen, is only 

 a variety of this species. 



The larva has been fully described by Foley (1912) and Langeron (1918). 

 According to Langeron's figures the innermost shoulder-hair is only trifid at the 

 tip, but in a number of specimens he has sent me from Tozeur, as well as in some 

 skins sent by Capt. Barraud from Palestine, it is branched almost from the base 

 and somewhat plumose. The head of the larva is extremely dark, the usual markings 

 being all fused in most specimens into a large black patch which occupies the greater 

 part of the head, leaving the front of the clypeus yellowish. The lower surface of 

 the head, as well as the upper, is mainly blackish. 



The egg as described and figured by Foley (reproduced in fig. 2, k) is very dis- 

 tinctive, and quite unlike that of A . hispaniola or A . turkhudi. The species is said 

 to breed in highly saline desert pools, or in brackish water near the sea. 



Distribution.— Desert regions of North Africa from Southern Algeria to Egypt ; 

 Palestine ; Teneriffe. Not certainly known from further east or north. 



Tribe Cui.iciNi. 



I propose to revert to the old classification of mosquitos, and recognise only two 

 tribes, the Anophelini and Culicini, including in the latter the Megarhinini and 

 Sabethini. I am now convinced that Howard, Dyar and Knab were right in 

 including Megarhinus in the Culicini and placing it somewhere near Psorophora ; 

 the modifications of the adults, though striking, are not fundamentally important. 

 On the other hand, I am equally convinced that the tribe Sabethini cannot be 

 maintained. Every character on which it has been attempted to define it breaks
