ON THE MOSQUITOS OF MACEDONIA. 11 



This species formed only a small percentage of the mosquitos taken in tents, etc. 

 Once or twice blood-gorged females were taken in such situations, but though 

 doubtless a common biter, no specific complaints against it were made. Some 

 hundreds of examples in all were bred out, and the average size is decidedly small. 

 Larger examples had however begun to appear in late November and early December. 



Culex hortensis, Fie 



This species was first identified from the Lahana district, where it occurred in 

 three localities : — (a) Near Hadji Bairamli in a partly artificial pool near one of our 

 camps (see notes on C. pipiens). This site was quite in the open, though there were 

 one or two isolated trees near, (b) In the Likovan stream ; and (c) on the Mahmudli 

 spur — larvae sent by Capt. Lovell-Keays (24th Sept.). Later one <$ and one $ 

 were bred from larvae from Lake Amatovo (Oct. 1917). Ficalbi, who found hortensis 

 in many places in Italy, considers it a sylvan species and believed it lived on the 

 juices of plants, neither attacking animals or man, nor occurring in houses. I have 

 not seen the precise spot on the Mahmudli Spur where the third lot of larvae — which 

 produced only males — were gathered, but the other sites are in open country, though 

 patches of scrub, vineyards and woody nullahs occur near by. But males, and on 

 one occasion what was apparently the blood-gorged female, were certainly found 

 along with C. pipiens in tents, etc. C. hortensis is similar to, but a little smaller 

 than, C. pipiens. It is a blackish or dark greyish mosquito with nearly white bands 

 at the apices of the abdominal segments, in which the scales are relatively broad ; 

 while pipiens is a browner or dark buff species with paler bands at the bases of the 

 segments. The male of hortensis can be told at a glance, with a low power lens, by the 

 sparsely clad palpi and stout thumb-like inner chitinous lobe of the side-pieces of 

 the genital armature. 



Uranotaenia unguiculata, Edw. 



U. unguiculata, Edwards, Journ. As. Soc. Bengal, ix, p. 51 (June, 1913). 



Of this very interesting small mosquito Major C. Joyeux bred a few examples 

 from larvae collected at (a) Vlochichta, near Koritza, and (b) Yenidje-Vardar. He 

 also found this species (larvae only) at Kastorta. Four imagines examined from the 

 first locality bear the date 24th Sept., and two from the second 15th and 17th May, 

 respectively. I have myself only one specimen ( $) bred from a larva taken from 

 a pool beside the Vardar, north of Karasouli (9.x. 17). The larva will shortly be 

 described and figured by Major Joyeux. 



U. unguiculata is remarkable for the extreme development of the upper of the 

 two lateral fines of bluish white scales towards the front of the mesonotum. 

 These lines however do not meet antero-medianly. U. unguiculata evidently belongs 

 to the African bilineata group. In making his description, Edwards had before him 

 a single $ (now in the Indian Museum, Calcutta), but the species has since occurred 

 in Egypt (Boulac Dacrur, 20.xii.1908, Dr. L. H. Gough, 1 <$ in British Mus., det. 

 F. W. Edwards). U. unguiculata is the only Uranotaenia found in the Palaearctic 

 region and the above records form a considerable extension westwards of ita 

 ascertained range.
