Genus Cellia. 105 



for the malarial parasites, viz. Cellla pharoensis, Theobald, Cellia 

 argyrotarsis, Desvoidy, and Cellia albimana, Wiedemann. 



It is one of the most marked genera of this section, the dense 

 scaling and lateral tufts being marked in all the eight species. 



The life-history of three is well known, namely, pulcherrima, 

 argyrotarsls and albimana (albipes). 



That of pulcherrima has been worked out by Liston and James, 

 albimana by Dr. Grabham, argyrotarsis by Goeld and Lutz. 



The adults as seen in C. pharoensis and C. pulcherrima are 

 found in houses, barracks and native huts. 



The genus occurs in Asia, Africa, South America, and the 

 West Indies. The following species are known : — 



1. C. pharoensis, Theobald, Mono. Culicid. I., p. 169 (1901) (Africa, West,
