INDIAN SPECIES OF ANOPHELES 235 



much darker. Abdomen dark brown. Legs brown, speckled and 

 not conspicuously banded, the last tarsal segment of the hind leg is 

 entirely dark. Costa with six black spots, the two basal ones small. 

 Egg (Plate XXXIV, fig. 2) with a broad upper surface, the floats arising 

 from the rim. Larva with simple and unbranched frontal hairs. Pal- 

 mate hairs only on the abdominal segments ; leaflet long and pointed, 

 very similar to that of rossii, but rather shorter. This species occurs 

 almost all over the plains of India ; it has been recorded from the 

 Punjab, Bengal, Bombay, Central Provinces, the Berars, Sind, Assam, 

 and South India. It is an important natural carrier of the parasites of 

 malaria. Bentley, who has made a careful study of its habits in Bombay, 

 notes that it is a domestic species, breeding in wells and cisterns, 

 in collections of fresh water of every kind, in brackish water, and 

 water that contained more salt than sea water. Larvae which hatch 

 out in fresh water die when placed in salt water, but those which hatch 

 out in salt water live and develop into mosquitoes. The larvae are able 

 to remain twenty minutes under water. In Madras this species breeds 

 in both used and disused wells in the town ; the authors found numbers 

 of larvae in a well which was in constant use by no less than four 

 families. In Mian Mir it breeds in tins of water. 



Anopheles (Cellid) pulcherrima, Theobald. Palpi brown with four 

 white bands, the apical one broad and including the tip. Thorax dark, 

 with three longitudinal rows of white scales. Legs dark and speckled, 

 the last three and a half and sometimes three and three-quarters of the 

 hind tarsal segments entirely white. Costa with six black spots, the 

 basal ones small. Egg much the same as that of stephensi, but the rim 

 is much broader. Larva with simple and unbranched frontal hairs. 

 Palmate hairs absent from the thorax ; leaflets moderately long, the 

 filament very long. This species is common in many parts of the 

 Punjab, the North-West Frontier, and the Bombay Presidency. The 

 larvae have been found in rain pools. 



Anopheles (Myzorhynchus) barbirostris, Van der Wulp. Palpi dark, 

 heavily clothed with scales, but without bands. Thorax dark, with some 

 silvery scales. Abdomen brown. Legs dark brown without any true 

 bands. Costa with a small patch of white scales at the junction of the 

 apical and middle thirds, and another at the apex. Larva with a branch- 

 ed hair on the inner side of the antenna ; median frontal hairs simple, 

 occasionally forked ; external hair branched, forming a cockade. Palmate 

 hairs present on the second to the seventh segments ; leaflets short 

 and broad, filament short. This species is found scantily in most parts
