Larva of M. turkhudt. — The larva is Culex- 

 like in some of its characters, though undoubtedly 

 much more nearly related to the Anopheltne type. 



The full-grown larva is distinguished by the 

 adoption of the slightly hanging attitude. The 

 chief characters of the larva are : — 



1. Two large additional frontal hairs are 

 developed, which reach as far forward as the 

 longest of the hairs described in other larvae. 



2. The shape of the head differs from that 

 of the ordinary Anopheltne larva. 



3. The palmate hairs are only represented 

 on two or three abdominal segments, namely, 

 the fourth, fifth, and sixth. They are absent on 

 the first three abdominal segments. 



4. The palmate hairs are small and poorly 

 developed. The leaflets are irregular and the 

 terminal filament blunt. 



This species must be looked upon as a form 

 which in its egg and larval stages has lost many 

 of the characteristics of Anopheltne eggs and larvae, 

 and has approached in these stages the characters 

 of the eggs and larvae of Culex.
