66 « THE MOSQUITOES OF EGYPT, 'THE SUDAN AND ABYSSINIA posterior cell nearly as long as the cell; supernumerary and mid cross-veins in one line, posterior cross-vein about its own length distant behind the mid.

Halteres with pale stem and fuscous knob.

Legs brown with very narrow apical yellow bands. Length. 4.5 to 5 mm. Habitat. Baro and Pibor.

Observations. Described from several females, but all have been slightly damaged, the wings are very characteristic and approach nearest to Giles’s Anopheles gigas from India. Dr. Balfour states that “ it boarded the steamer in the evening at Baro and bit freely.”

There is variation in the wing marking especially in the size of the black spots on the wing field. It is abundant on the Baro.
