= An. pUtiniger, Donitz. Insect. Borse, Jan. 1901. Specimens of this 

 supposed new species proved to be partly examples of An. barbirostris 

 and partly of An. sinensis.

"Wing intensely black, with a small apical spot, a single tiny 

 interruption of the costa, opposite the middle of the fork stems, 

 and two basal dots of a much clearer white than in the allied 

 species ; the fringe is black at the apex and elsewhere, except 

 opposite the junctions of III, and post. V, and over a rather 

 long space about that of ant. V ; there are only two or 

 three white spaces on the long veins. Legs sooty, wnth small, 

 but obvious apical white rings to the tibise and tarsi. Thorax 

 black, with a dorsal patch of grey bloom, and some appearance 

 of linear marking, imparted by irregular lines of scattered, golden 

 linear scales. Abdomen black, nude, with brown hairs. Head 

 and appendages entirely black except for a white frontal tuft, 

 and greyish tips to the otherwise black fork-scales of the nape. 



There is no need to give any further description of this very distinct 

 species, the differences from the Sinensis group having been already 

 sufficiently indicated. 



In the Nortli-west Provinces of India it is one of the commonest 

 species of the genua, and may be seen about much later in the year 

 than An. Bossii. It is noticeable that males are to be met with in 

 considerable numbers, long after the females have hidden themselves 

 for the winter, and I took one of these on November 20th, in Shahjahan- 

 pur, last year. Length. — 5 to 6 mm. 



Habitat. — Straits Settlements, Upper IBurmah, Calcutta, North-west 

 Provmces, and Punjab, India.
