MOSQUITOS OF THE PALAEARCTIC REGION. 279 



The larva has not been fully described. It may be diagnosed as follows :— 

 Antennae with a minute single hair before the middle. Frontal hairs all simple, 

 and all about equal in length, the inner anterior pair widely separated, the posterior 

 pair almost immediately behind the inner anterior. Head markings fairly constant, 

 arranged as in the figure, the spots small. Innermost shoulder hair plumose 

 from ijase to tip, the hair next to it also plumose, but longer and with fewer branches. 

 No rudimentary palmate hairs on thorax or on first abdominal segment ; a pair of 

 small ones on the second segment, and fully developed pairs on segments 3-7 ; each 

 fully developed hair has about 16 leaflets, which are lanceolate, with two or three 

 jags beyond the middle, fomiing a rather indefinite shoulder ; terminal portion 

 long, but not nearly as long as the basal. No difference could be detected between 

 Macedonian and Indian specimens. 



The species is said to be associated with mountainous districts, though by no 

 means confined to high altitudes, and to be largely a stream-breeder. 



Distribution.— Esistem Mediterranean region, from Italy to Macedonia and 

 Palestine ; thence through Upper Mesopotamia and Persia to the Punjab. 

 Also recorded from North Africa, though I have seen no specimens from there. 

 Transcaspia (Firudza, C. Ahnger). 



16. Anopheles (Myzomyia) sergenti, Theo. 



Pyretophorus sergenti, Theobald, Mon. Cul. iv, p. 68 (1907). 



This species very much resembles A. supeypictns. but is rather smaller, and 

 differs as indicated in the key. I have previously considered it identical with the 

 Indian A. culicifacies, but whereas in A. sergenti there are four or five pale spots 

 in the wing-fringe, in A. culicifacies there is never more than one. .4. sergenti 

 might equally well be regarded as a variety of the African A . funestus, which has 

 several pale fringe-spots, but is much darker in general coloration, and has the thu'd 

 vein much less extensively pale. Detailed comparisons of these three species in all 

 their stages are necessary before final conclusions can be reached as to their exact 

 relationships. 



Distribution.— A]gcYm [Sergent] ; Tunis (Tamerza, Dr. M. Langcron) ; Palestine 

 [Annandale, Barraud). 



17. Anopheles (Myzomyia) hispanlola, Theobald (lig. 2, m). 



Myzomyia hispaniola, Theobald, Mon. Cul. iii, p. 49 (1903). 



Pyretophorus myzomyfacies, Theobald, Mon. Cul. iv, p. 69 (1907). 



Apparently only differs (in the adult) from A . multicolor in having leaflets present 

 on the male aedoeagus, and hairs instead of narrow scales on the scutum ; according 

 to Sergent & Foley the eggs of the two species are remarkably distinct. The wing- 

 markings of both species (especially A. multicolor) are so variable that no constant 

 cUfference can be found between them. A. hispaniola is quite indistinguishable, 

 so far as I can see, from the Indian A. tiirkhudi in the adult state. The egg of 

 -1. hispaniola as figured by Sergent is, however, so difterent from that of A.tiirkhiidi 

 as figured by Christophers that, unless a mistake has been made by either author, 

 it is impossible to regard the two as conspecific, especially as they are widely discon- 

 tinuous in their distribution. The larvae also differ, according to the published 

 descriptions, in the number of pairs of palmate hairs present ; but this requires 

 confirmation, since the figure given by James and Liston is inconsistent with their 

 description. 



This species is apparently much less fond of desert conditions and saline water 

 than A. multicolor.
