MOSQUITOS OF THE PALAE ARCTIC REGION.

than the smallest C. pipiens, the integument of the thorax is generally paler and the 

 scales browner. The long, bare male palpi will at once distinguish that sex from 

 C. pipiens as well as from all other Palaearctic species except C. pusillus and C. hortensis. 

 The pale markings of the abdomen have an ochreous tint ; the colours of the 

 tergites are either separated in a straight line, or the pale lateral stripes are slightly 

 enlarged apically. 



Distribution. — Italy (Ficalbi) ; Hungary [Kertesz ; also Neusiedler See, Mik) ; 

 Macedonia (Waterston) ; Asia Minor (Salyr, Konia and Bashara, Naday) ; Palestine 

 (marsh at Tel Abu Zeitun, Austen) ; perhaps the species recorded from Rumania 

 by Leon as C. fusculus.

I did not at first distinguish this species from C. modestus, and it was recorded 

 by Barraud under this name. It closely resembles C. modestus, but differs quite 

 markedl}^ in the male hypopygium. The claspers are shorter and stouter, there 

 are differences in the lobe of the side-piece, and the anal and genital parts are much 

 more elongate and rather differently constructed. The pale markings of the abdomen 

 are pure white, and thus differ in colour as weU as in form and position from those 

 of C. modestus. 



I have examined the original specimens of Macquart's C. pusillus, one of which 

 is in the Vienna Museum and the rest in the Bigot collection in Mr. CoUin's possession.
