Groups VI, VII, VIII. 



These mosquitoes are of moderate size and of a light brown 

 colour. Their colour permits them to be readily seen on any dark 

 surface on which they rest. The larvae are, for the most part, 

 found in puddles, shallow pools, and pots. They have simple un- 

 branched frontal hairs. The eggs have a broad " deck " surface, 

 the floats are placed rather low down in rossi and higher up in 

 stephensi, so that in the latter the deck area is encroached upon. 



Observations. The mosquitoes of this group contrast with 

 those of group V in being light coloured and therefore readily seen 

 and caught ; they breed in still water ; and probably play little 

 part in the propagation of malaria, although intimately connected 

 with man. Under the detailed description of each mosquito will be 

 found arguments for placing rossi near to punctulatus and stephensi 

 near to willmori. The close \ resemblance of rossi to costalis of 

 Africa, both in structure and habits, is noteworthy. 



GROUP VII. 



In this group at present we can class only one Indian mosquito, 

 viz., turkhudi. This mosquito in the scale structure of the adult 

 approaches closely to group V and has been classed by Theobald 

 in his genus Myzomyia. It differs, however, from all other Indian 

 anopheles (except nagpori, a single specimen of which alone has 

 been taken) in having the tips of the palpi black, although there 

 are three light bands on the palpi. The larval and egg characters 

 too contrast markedly with other ' 'anopheles." Turkhudi is a large 

 brown mosquito with characteristic long thin palpi. The larvae are 

 always found in still water, chiefly by the side of river-beds in the 

 pools formed in the soft mud by the feet of cattle. The larva has 

 simple unbranched frontal hairs, and an additional hair is also found 

 overhanging the mouth. The palmate hairs are small and 

 badly developed, and found only on a few of the abdominal 

 segments, hence the larva does not lie quite flat on the surface 

 of the water like an ordinary ' 'anopheles." The eggs are peculiar 

 in that the floats are practically absent. 



GROUP VIII. 



The two mosquitoes included in this group, viz., gigas and 

 lindesayi, have been found only in the hills. Little is known of their 

 life-history or habits.
