374 Anopheles barbirostris. (Van der Wulp.)

' Leyden Museum Notes,' 6, p. 48, Van der Wulp ; ' Mono. Culicid.,' 1, p. 146 (1901), Theobald.

Thorax deep grey with slaty reflection, dark longitudinal lines and minute black specks, with long scattered golden hair-like scales. Palpi densely scaled, entirely black, palpi and scaled proboscis forming a very prominent black projecting mass. Abdomen nearly black. Legs dark brown, usually unbanded, but with sometimes narrow apical and basal banding. Costa black, with two small yellow spots ; apical fringe black, except between the second and third veins. Scales much more robust than in A. sinensis and its sub-species.

Length, 5 mm.

Habitat. Calcutta ; Selangor ; Old Calabar (West Africa).

Observations. This Malay and East Indian species, which has also recently been found in India, can at once be told from the others of this group by the entirely blqck palpi and the much broader wing scales. Dr. Christophers sent me a note (undoubtedly concerning this species) from Gopal Chunde Chatterpee, stating that in living specimens the halteres are to be seen rythmically moving backwards and forwards, and thus differing from sub-species nigerrimus, in which the halteres are not so fully developed, and do not move about.

Anopheles gigas. (Giles.)

' Ento. Mo. Mag.,' p. 196, vol. 37, 1901, Giles ; ' Mono. Culicid.,' 2, p. 308, 1901, Theobald.

Thorax fawn coloured in the middle, dark brown on each side ; abdomen dark brown ; palpi long and thin, deep brown ; legs dark brown, with basal pale banding, especially to the hind legs, bases of the legs pale, almost white.

Wings with two large black spots on the costa and black patches on the wing-field ; fringe pale where the veins join the border of the wings except at the ends of the fifth vein, which have a pale patch between them.

Length. 6 to 7 mm.

Habitat. Conoor, Nehilgerri Hills, India.

Observations. The largest and handsomest Indian anopheles I have seen. The two pronounced black costal spots should at once identify it. Taken at an elevation of 6,000 feet.

Anopheles metaboles. n. sp.

Thorax brown, with frosty-grey scales in the middle, the brown forming a broad line on each side. Abdomen deep brown with golden
