 is unsatisfactory, the larger the number of the character-

 classification. 



The important subdvisions of the Culicidae are : 

 CORETHRIN^E. Proboscis adapted for suction and not 

 for penetration. 



Megarhinina. Proboscis very long and curved. Palps 

 long, ist fork cells in wings very short. Scales on veins 

 of wings small. Scutellum, lateral lobes very small. 

 Larvae are larviverous. Very short respiratory siphon. 

 Eggs oval, thick shelled.

FIG. 68. Neuration of wing characteristic of Culicidge (Theobald). 



Anophelina. Proboscis straight. Palps same length 

 as the proboscis in both sexes, clubbed in male. Scutellum 

 not lobed. Scales on veins of wings usually lanceolate. 

 Scales on thorax and abdomen rarely abundant. Larvae 

 asiphonate. Eggs with lateral air-floats. 



Culicina. Proboscis straight. Palps short in female, 

 in male as long or longer than the proboscis. Wing 

 scales variable. Scales on thorax and abdomen 

 abundant. Scutellum trilobed. Larvae always siphonate ; 

 the siphon may be long or short. Eggs variable ; may 

 be in rafts or thick-shelled eggs deposited singly.
