Anopheles theobaldi. 



rental hairs being arranged like the veins of a leaf. A prominent 

 pair of palmate hairs is present on the thorax in addition to those 

 on the abdominal segments. The shape of the palmate hair leaflets 

 is shown in the figure (B). 



Habitat and observations. This species occurs in small num- 

 bers in the Central Provinces (Nagpur), and more commonly in 

 some parts of the South of India, Travancore, Goa, &c., and in the 

 Bombay Presidency (Karwar). Outside India it occurs in 

 Mashonaland and Mauritius. A variety in which the hind legs are 

 less banded is described by Mr. Theobald under the term indiensis.

Palpi with three white bands, the two anterior of which are 

 broad and the posterior narrow. Wings light coloured, spotted with 

 black. Legs speckled ; the last two segments of the tarsi of the 

 hind legs pure white. 



Palpi black with three white bands ; the apex is white-scaled, 

 the second band is at the joint between the apical and the third 

 segment, and the third band is at the joint between the third and 

 second segments. 



Proboscis black with a white tip. 



Head covered with black and white scales ; a prominent bifid 

 tuft of white hairs projects forward from the head. 



The thorax is covered on its dorsal surface with white scales 

 and hairs inserted on a dark ground, the scales and hairs being 

 arranged so as to show a median and two lateral darker lines. The 

 lateral aspects of the thorax are of a dark colour. 



The abdomen is intensely black. It is covered with long white 

 hairs. Mr. Theobald says that the apical segments have " small flat 

 scales of a dull golden hue." We have been unable to detect the 

 presence of these scales in the examination of a number of speci- 

 mens, and Colonel Giles originally described the abdomen as " nude." 

 The point is of importance, as the position of the mosquito in the
