ON THE MOSQUITOS OF, MACEDONIA. 9 



September ; .on 25th August a large brood hatched out from a pool, and a similar 

 hatching was noted about four weeks later. The species continued to be taken well 

 •on into October.

Theobaldia annulata, Schrank. 



During the last week in September a darker, stouter example was noticed in a 

 'batch of full-fed longiareolata larvae. The specimen was isolated, and pupating on 

 30th Sept. produced on 4th Oct. a female of annulata. A pure strain of annulata 

 was later found in a well near the Experimental Farm at Mikra (24. xi. 17) and from 

 these larvae several imagines were reared. They were still emerging during the first 

 week of December. The siphon of all these larvae is broader and the spines of the 

 comb less numerous and stouter than in any English examples of annulata that I 

 have seen. 



Genus Culex, Linn. 



Besides the species dealt with below, a single male of the pipiens group was raised 

 from larvae taken in Lake Amatovo in November. The palpi were scantily set with 

 bristles (cf. hortensis) and there are some colour differences of uncertain value. The 

 genitalia are neither those of pipiens nor oi fatigans. For the latter, careful seaich 

 has been made, but without result. In a long series of preparations of the male 

 rgenitalia only pipiens could be detected. 



Culex mimeticus, Noe. 



A conspicuously spotted insect with a superficial Anopheline appearance, 

 occurring all over the country but nowhere very numerous. It is a stream-breeder, 

 and we took it in various nullahs round Lahana, Likovan, Milovci (Giol Ajak), and 

 ibelow Oreovica. Dr. Niclot and others reared it from the neighbourhood of Salonika;
