ON THE MOSQUITOS OF MACEDONIA. 7 



On a last visit to Amatovo (29.xi.17) no larvae could be found and only an 

 occasional Chironomus and a Dixa were beaten from the reed-beds. 



A. sinensis breeds on till late in the season. Two blood-gorged females were taken 

 in a tent at Karasouli and, after being given two days to clear up, were transported 

 to the unwarmed Laboratory at the base (13th Oct.). On the morning of the 21st 

 numerous empty egg-shells were found on the water over which the females had been 

 confined. The gut of the young larvae was well filled and they were probably 2-3 

 days old. The first change of skin took place on the 24th-25th. There was no 

 subsequent change, all dying by about the middle of November. 



Stegomyia fasciata, F. 



This species is said to be exceedingly common within the town of Salonika, 

 occurring particularly in churches, etc. Many complaints of its persistent biting 

 have been received. Major Armour showed me one or two examples taken at 

 Kalamaria, where however I have seen only a single specimen alive. Before leaving, 

 I received several examples from Lt. J. M. Wallace, taken at the Base Laboratory. 

 How far S. fasciata is to be found inland is deserving of attention, but no data are 

 at hand, nor in numerous collections made near the town were larvae of this species 

 encountered. 



Genus Ochlerotatus, Arrib. 

 Ochlerotatus dorsalis (Mg.). 



In the last week of September and during the first half of October this species 

 was annoying and persistent in its attacks in the Kalamaria District, in houses, 

 tents, wards, etc. It was active in the early evening and late afternoon and attacked 

 one viciously. No signs of breeding-places could be discovered in the hospital, where 

 it was most regularly seen ; but about three-fourths of a mile off, on flat ground by

the shore, its numbers increased, and here there had been recently some standing 

 pools behind the beach. Along the shore of Mikra Bay it was frequently found, and 

 in the marshes it was in thousands. Col. Wenyon took about this time several 

 examples of Ochlerotatus on the Struma, which appear to belong to this species ; 

 the specimens are however much rubbed. Like those from Mikra they bit severely.
