Genus DUTTONIA. Newstead (1907). 
Aims. Trop. Med. and Parasit. I., No. 1, 17 (1907), Newstead. 
Head of female clothed principally with flat scales, with 
narrow-curved ones behind, and a row bordering the upper half of 
the eyes; upright forked-scales on the dorsal area. Mesdthorax 
with small narrow-curved and minute hair-like scales ; scutellum 
with flat scales, • the lateral lobes small , somewhat tuberculate , 
and furnished with eight bristles . Palpi short. Fork-cells long, 
almost equal; lateral vein scales long and narrow, but broaden¬ 
ing towards the apex of the wing. Male with the anterior tarsi 
sub-chelate. 
This genus is closely related to Aedimorphus (Theobald), but 
differs in the presence of narrow-curved border-scales to the eyes 
and the character of the lateral lobes to the scutellum. The 
number of bristles to the small lateral lobes is also unusual, and 
moreover there is a complete absence of flat scales to the meso- 
thorax.
