232 MEDICAL ENTOMOLOGY 



Egg and larva unknown. The species is fairly common in Quetta at 

 certain times of the year. Mrs. Davys says that it breeds in open pools, 

 and irrigation channels. 



Anopheles (Pyretophorus) ntirsei, Theobald. Closely allied to nigri- 

 fasciatus ; palpi with a well-marked apical white band. According 

 to Mrs. Davys it is one of the commonest anophelines in Quetta, and 

 breeds in the same kind of places as nigrifasciatus ; the larvae are 

 able to remain as long as eight minutes below the surface. 



Anopheles (Nyssorhynchus) maculatus, Theobald. Palpi with three 

 white bands, the apical one including the tip, and only separated from 

 the next by a narrow dark band. Thorax brown with lighter sides. 

 Abdomen dark brown. Legs brown and speckled ; the last tarsal 

 segment of the hind leg is entirely white. Costa with four long black 

 spots, and three smaller basal ones. Egg with frill interrupted by the 

 floats, which touch the upper margin ; floats short, about one-third the 

 length of egg. Larva with simple and unbranched frontal hairs ; 

 palmate hairs present on second to seventh abdominal segments ; leaflet 

 moderately long, filament very short. This species is common in the 

 Bengal Duars. 



Anopheles (Nyssorhynchus) fuliginosus, Giles. (Plate XXXVII, fig. 2.) 

 Palpi black with three white bands, the basal one narrow, the next 

 broader, and the apical one, which includes the tip, broad. Thorax dark 

 brown. Abdomen dark, almost black. Legs black, narrow, with distinct 

 bands at the fore and mid tarsal joints ; last three tarsi of hind leg 

 pure white. Costa with six long black spots separated by small white 

 spots. Egg (Plate XXXIV, fig. 8) with rather broad upper surface and 

 well-marked frill, which is encroached on by the floats. Larva with 

 frontal hairs with few branches, the external with more than the 

 internal. Palmate hairs only present on the abdominal segments ; leaflet 

 moderately long, serrated and with a long spine. 



This species is widely distributed, and is common in Calcutta and 

 other parts of Bengal, in many parts of the Punjab, in Bombay, Goa, 

 and the Central Provinces ; it is also common in many places in 

 South India, including Madras City. It breeds in pools, ponds and 

 tanks with vegetation at the sides, and is a natural carrier of the 

 parasites of malaria. 



Adie has noted a distinct but unnamed variety, in which the palpi have 

 four narrow white bands, and the last two and a half or two and three- 

 quarters of the hind tarsal segments are white. It is found at 

 Ferozpore and Amritsar in the Punjab, but only at certain seasons.
