548 A Monograph of Culieidae. 



Abdomen black, with small, nearly basal, lateral white spots ; 

 border-bristles dull brown; venter brown. 



Wings with brown scales ; the lirst sub-marginal cell a little 

 onger, but no narrower than the second posterior cell, its stem 

 about two-thirds the length of the cell, its base nearly level with 

 that of the second posterior cell ; stem of the latter as long as 

 the cell ; posterior cross-vein about one and a half times its own 

 length distant from the mid cross-vein. 



Halteres with ochreous stem and fuscous knob. 



Legs deep brown, unhanded \ femora rather thickened, 

 slightly hairy ; tibiae with long bristles and a row of short ones, 

 also a few apical bristles ; ungues equal and simple. 



Length. — 4 mm. 



Habitat. — Jugra, Kuala Lumpur, Federated Malay States (Dr. 

 Durham). 



Time of appearance. — September. 



Observations. — Described from a ? in perfect condition, bred 

 out by Dr. Durham from a larva collected in the hospital 

 reservoir at Jugra. It certainly comes well in the Genus SJcusea, 

 but there are only five lnid-scutellar bristles. It is a day flyer. 

 In many respects it bears a strong remblance to Skusea multiplex, 

 Theobald, but differs in having simple ungues and an unadorned 

 thorax. 



Genus LEPTOSOMATOMYIA. Theobald. 

 Ann. Mus. Nat. Hung. III., p. 110 (1905). 



Head clothed mostly with flat scales, a few narrow-curved 



ones in the middle line and upright forked scales behind. 

 Antennae in the <J slightly plumose ; palpi in $ very short. 



Thorax with narrow-curved scales, also the prothoracic lobes ; 

 scutellum with small flat scales to the mid lobe, narrow-curved 

 ones on the lateral lobes. Fork-cells of <J short ; median vein- 

 scales mostly in single line ; lateral vein-scales linear, rather thick. 



Distinguished from other Aedifae genera by the cephalic and 

 scutellar squamose characters.
