MOSQUITOS OF THE PALAE ARCTIC REGION. 345 



hypopygium in the paper quoted. According to Storey the larvae are indistinguish- 

 able from those of C. perexigtms. 



Distribution. — An Ethiopian species, known from Madagascar, Zanzibar, and 

 the Congo, which has also been recorded from Egypt by Storey as C. invidiosus. 

 Also found in Egypt by Austen (Kantara, Suez Canal). Perhaps occurs in Palestine 

 (Acre and Jerisheh, Austen; females only).

 (1915). 



This species may be distinguished from C. pipiens by the combination of some 

 or all of the following characters : — Mesonotal scales somewhat coarser, with a 

 dull brownish-ochreous instead of a dark brown or reddish-brown tinge (but 

 Japanese and American specimens are often as red-tinged as C. pipiens). Upper 

 fork-cell shorter in both sexes, that of the female being less instead of more than 

 three times as long as its stem. Male palpi somewhat shorter and less hairy. Pale 

 abdominal bands of the female rather more rounded. The only absolutely rehable 

 distinction between the adults is, however, in the structure of the aedoeagus (see 

 figures in Bull. Ent. Res. iv, pp. 54, 55). The larvae are rather more easily separated 

 than the adults by the characters mentioned in the key. 



Distribtdion. — This species, almost universal in the tropics, has a very limited 

 area of occurrence within the Palaearctic region. I have only seen it from Lower 

 Mesopotamia [Barraud), Seistan, eastern Persia {Annandale), and Japan (Kobe and 

 Nagasaki, Lamborn). It has been recorded by various observers from southern 

 Europe and North Africa, but I consider it highly probable that all such records 

 refer to other species.
