MOSQUITOS OF THE PALAEARCTIC REGION. 303 



3. Aedes (Ochlerotatus) mariae (Sergcnt) (Tigs. 6 b, 8 c, 9). 



Culex mariae, Ed. & Et. Sergent, Ann. Inst. Pasteur, xvii, p. 62 (early in 1903). 



Before having examined specimens of the true A . piilchritarsis, I took A . mariae 

 to be s^iionymous with Rondani's species, but the two are in fact chstinct. 0. 

 mariae has the wings, femora and tibiae, and even the tarsi in part, densely speckled 

 with pale scales ; the tarsal rings are creamy white and not very sharply marked ; 

 the mesonotal scales are almost uniformly ochreous without any bronzy tint. The 

 male hypopygium resembles that of 0. caspius, l:>ut the basal lobes of the side-pieces 

 are smaller and carry no spines. 



The Sergents' description of the larva being somewhat inadequate, fresh figures ' 

 are gi^'en here, prepared from specimens collected by Capt. Barraud. These figures 

 will explain themselves, but it may be specially noted that the antennae are almost 

 devoid of small spicules, a very unusual character for this genus ; the siphon is also 

 remarkable in being almost as broad at the tip as at the base, the base being feebly 

 or not at all chitinised (even in full-grown larvae) ; siphonal index 1-4-1 -6. (It 

 may be remarked here that Wesenberg-Lund's figure of the siphon of A. caspius 

 is inaccurate ; the tip in that species is really much narrower than the base.) The 

 anal gills in A . mariae are minute and globular, as usual in salt-water breeders ; the 

 saddle is extremely small ; formula of anal brush 10 4- 4. 



The species seems to be exclusively a salt-water breeder. 



Distribution. — Algerian coast [Sergcnt) ; Southern France (Segiiy) ; Palestine 

 coast (Athlit, Barraud) ; Syria (Beirut, Barraud). Probably occurs also along the 

 intervening Mediterranean coasts. 



4. Aedes (Ochlerotatus) zammittii (Theobald). 



Acartomyia zammittii, Theobald, Mon. Cul. iii, p. 252 (25th July 1903). 



This rather closely resembles A. mariae, the only difference I can detect in the 

 adult being the presence of two more or less definite longitudmal stripes of white 

 scales on the mesonotum, resembling those seen in 0. caspius. The male hypopygia 

 appear to be identical. The main reason for keeping the two distinct is the occurrence 

 of certain larval differences. The two larvae of A. zammittii in the British Museum 

 are both very much damaged, and one is immature, but the antenna has distinct 

 spicules, and the pecten teeth are shorter, rather more numerous, closer together, 

 and with more serrations than in A . jnariae ; it is possible they may have been wrongly 

 associated with the adults, and in any case it is very desirable that more and better 

 material should be obtained. If A. zammittii should prove identical with A. mariae, 

 the latter name will stand for the species ; it must have been published earlier, since 

 Theobald quotes it (Mon. Cul. iii, p. 354). 



Distribution. — Originally described by Theobald from Malta. I have also seen 

 specimens with a more or less distinctly white-striped thorax from Palma, Majorca 

 [Griinberg), and Southern France [Dollfus, per Dr. Langeron). 



5. Aedes (Ochlerotatus) pulchritarsis (Rondani). 



Culex pidchritarsis, Rondani, Bull. Soc. Ent. Ital. iv, p. 31 (1872). 

 Cidex leucacanthus, Loew, Beschr. Eur. Dipt, iii, p. 1 (1873). 



In the specimens which I have examined there are no pale scales on the wings, the 

 femora and tibiae are moderately speckled ; the tarsi are black, with sharply marked 

 white rings ; the mesonotal scales rather variable, usually dull bronzy-ochreous 

 with some patches of darker ones, sometimes, as in the specimens from Paris and 

 Chitral, a more or less distinct central white stripe. It is just possible that the species 

 ma}^ not be correctly identified, since Ficalbi in his detailed description says of the 

 (4183) y2
