Genus Cidiciomyia. 233 



basal areas, the third and fourth segments with more or less 

 triangular areas, the following with more or less complete bands. 

 Legs brown, unbanded. Wings of typical Culex form. 



9 . Head clothed with very small, narrow-curved, pale 

 golden scales in the middle, and passing as a narrow area up to 

 between the eyes ; on the sides and spreading some way on to 

 the occiput and around the eyes are flat dull grey scales, some- 

 what irregularly disposed, and

 pale scales in the middle at the Cephalic ornamentation. 



base of the second segment, the 



base of the third and fourth segments with grey triangular 



spots, the other segments with grey basal bands ; venter 



yellowish. 



Legs uniformly brown with ochreous reflections, coxae and 

 femora beneath ochreous ; ungues equal and simple. 



Wings with fork-cells moderately long, the first sub-marginal 

 longer and narrower than the second posterior, its base nearer 

 the base of the wing, its stem rather more than half the length 

 of the cell; stem of the second posterior about two-thirds the 

 length of the cell ; cross-veins very pale, the posterior more than 

 its own length distant from the mid. Halteres with yellow stem 

 and slightly fuscous knob. 



Length. — 3 mm. 



Habitat. — Muina, New Guinea (Biro, 1900). 



Observations. — Described from a single perfect 9 • It re- 

 sembles at first sight C. fatigans, Wied., but differs in (i) the 

 small reddish-brown narrow-curved scales which are of quite 

 different form to those in C. fatigans, and in the marked cephalic 

 scale arrangement. The flat scales spread some way on to the 

 top of the head in front, and are irregularly disposed, but the 

 typical narrow-curved head scales of Culex are present even to 

 the front just between the eyes, and cover most of the top of 

 the head. 



It can be told from the other two species in this genus by the 

 pale grey basal abdominal bands.
