Genus Wyeomyia. 597 



dull metallic tints ; nietanotum brown with short black chaetae ; 

 pleurae testaceous with silvery grey spots. 



Abdomen black, the fifth, sixth and seventh segments with 

 basal white bands, the sides of all the segments with basal 

 triangular white spots, most prominent on the basal segments ; 

 the abdomen is compressed basally, depressed apically. 



Legs blackish ; femora pale beneath, unbandecl, rather thick ; 

 ungues small, equal and simple. Wings with brown scales, the 

 lateral vein-scales linear, rather dense, first sub-marginal cell 

 longer and narrower than the second posterior cell, its stem 

 about two-thirds the length of the cell, stem of the second 

 posterior as long as the cell ; posterior cross-vein nearly twice its 

 own length distant from the mid. 



Length. — 4 mm. 



$ . Head clothed with flat dusky scales ; antennae brown, 

 the lower third with the long verticillate hairs, upper two-thirds 

 with dense short hairs only, except for one group of three or four 

 long ones towards the middle of the short-haired area ; palpi 

 small, black-scaled ; proboscis rather longer than in the 9 > black. 



Thorax clothed as in the $ ; prothoracic lobes white-scaled. 



Abdomen black with rich violet reflections and with basal lateral 

 white triangular spots ; apical segment expanded, basal lobes of 

 genitalia very large, scaly and hairy. Legs brown unhanded. 



Length. — 4 mm. 



Habitat. — Peradeniya, Ceylon (E. E, Green). 



Time of capture. — January and February (1902). 



Observations. — Described from a perfect $ and 9 • It is the 

 only member of this genus yet found in Ceylon. The general 

 appearance at once separates it from all allied forms, except 

 Phoniomyia longirostris, but the proboscis is shorter and not 

 longer than the body as in that genus. 



The metanotal chaetae are difficult to see, and the strange $ 

 antennae appear to be rather contorted. 



Wyeomyia (?) leucostigma. Lutz (nom. nud.). 

 Mosq. do Brasil, p. 14 (1904), Lutz (in Bourroul). 



Lutz refers to this species as being distinct from the other 

 two Brazilian Wyeomyia in a synoptic table. It has white scales 

 on the metanotum. 



Typical Wyeomyias have not, but the species is retained here 

 until the opportunity occurs of examining it.
