NEW CULICID.E FROM THE FEDERATED MALAY STATES. 259 



Observations. — Described from three males taken by Dr. 

 Durham. They come very near N. stcpliensi, the wing ornamen- 

 tation being ahnost the same ; the thoracic scales are spindle- 

 shaped, not narrow-curved, and the legs are not speckled. In 

 stephensi the hind legs are not white at their apex as in this 

 species. It also comes very near N. maculatas, but differs in 

 (1) the mid ungues of the male not being simple, and in (2) the 

 greater number of white hind tarsal segments. 



Genus Skusea, Theob. (Mono. Culicid. iii. p. 291, 1903). 



Skiisca diurna, n. sp. 



Head black, with a narrow pale median Hue, and paler at the 

 sides ; proboscis brown ; thorax richly brown scaled ; pleurae black, 

 with silvery spots ; abdomen black, unhanded, with basal lateral 

 silvery spots. Legs dark brown, unhanded, paler at the base and 

 beneath the femora ; femora rather swollen. 



J . Head covered with flat black scales, a narrow indistinct line 

 of dull creamy ones and a few pale dull blue ones at the sides ; a few 

 thick black bristles projecting over the golden eyes ; clypeus black, 

 truncated with a slight median depression, in certain lights with grey 

 sheen ; palpi and proboscis brown, the former very short ; antennae 

 brown, base of second joint bright testaceous. Thorax black, covered 

 with rather long rich- brown narrow-curved scales, a few paler scales 

 in front, over the head ; scutelluui deep brown with narrow-curved 

 brown scales, and five median border-bristles ; pleurae brown, with 

 silvery white spots. Abdomen black, with small, nearly basal, lateral 

 white spots ; border-bristles dull brown ; venter brown. Wings with 

 brown scales ; the first submarginal cell a little longer 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 ochraceous stem and fuscous knob. Legs deep brown, 

 unhanded ; femora pale ventrally ; bases of the legs slightly pallid ; 

 femora rather thickened, slightly hairy ; tibia; with long bristles and 

 a row of short ones, also a few apical bristles ; ungues et^ual and 

 simple. Length 4 mm. 



Hah. Jugra, Kuala Lumpur. 



Time of appearance. September. 



Observations. — Described from a female in perfect condition 

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

 reservoir at Jugra. It certainly comes well in the genus Shiisea, 

 but there are only five mid scutellar bristles. It is a day liyer. 

 It bears a strong resemblance to S. multiplex, but differs in 

 having simple ungues and unadorned thorax.
