Groups II, ///, IV. 



GROUP II. 



This group includes moderately large mosquitoes, in scale struc- 

 ture approximating to the above group, i.e., with long white and 

 golden hair-like scales on the thorax, the wing scales spindle-shaped, 

 not so broad as in nigerrimus. It includes elegans and punctulatus. 

 The only specimens of this group, so far as we are aware, collected 

 in India, were taken by Dr. Cogill in Karwar. Dr. Donitz has 

 found species of this group in Sumatra and Borneo. 



Habits and character of the larva. The larvae of elegans were 

 found, when water was abundant, in the open, but, as a rule, they 

 were found in jungle springs. The larva has simple unbranched 

 frontal hairs, and well developed palmate hairs. 



Observations. Little is known of this group. It may be 

 remarked that in many characters rossi approximates to this group, 

 e.g., in the character of the scales and hairs on the thorax and 

 abdomen, and in some of the larval characters and habits, but the 

 wing scales of this group are considerably broader and somewhat 

 shorter than in rossi. 



GROUP III. 



This group includes at least two known Indian species, pul- 

 cherrimus and ivillmori. Probably also Stephens* should be included 

 in this group ; it has, however, been classed with rossi in a separate 

 group because of its similar habits and its marked association with 

 human habitations. 



The mosquitoes of this group are very beautiful and are covered 

 with broad white and dark brown scales on the thorax, abdomen and 

 wings. They are comparatively rare and little is known of their 

 habits ; they are at once recognised by their very scaly structure. 

 The larvae have been found in clear pools of water ; those of pulcher- 

 rimus have the median frontal hairs simple, while the external angu- 

 lar are branched. 



GROUP IV. 



This is a large group of black and white mosquitoes, the majority 

 of which have one or more tarsal segments of the hind legs white. 

 The larvae have well developed palmate hairs ; each leaflet, as a rule, 

 has a well-marked blade and rather a short terminal filament. The 

 frontal hairs are more or less branched, most branched in fuligmosus
