Genus Stethomyia. 61 



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

 Durham). 



Time of capture. — January and December. 



Observations, — Described from two $ 's bred by Dr. Durham. 



It is a very delicate-looking species, and differs completely 

 from the dark Stethomyia nimba, Theobald (Mono. Culicid. III., 

 p. 62). 



Type in the British Museum (Nat. Hist.). Dr. Durham 

 sends me the following note concerning this species : — 



"Sunday, Jan. 18, 1903. Larvae and pupae collected about 

 two miles away (from Kuala Lumpur) in a pool in the jungle. 

 Clear water pool, surrounded and more or less hidden by shrubs 

 and ferns ; looks as if it might have been a drinking-water 

 dripping well since abandoned, about four feet in diameter and 

 two or three feet deep, near a stream and some dried-up swamp 

 where Culex mimeticus larvae had been caught. Numerous small 

 dark Anopheles-like larvae which all died before transforming ; 

 there were also some quite minute pupae. Only two hatched 

 out."

 tomentum and hair-like brown curved scales. Legs long and

 iridescence or fawn colour. Wings unspotted. Prothoracic lobes 

 apparently stalked.

 slender hair-like scales it is covered with a short fine tomentum or 

 frostiness such as is often seen in Anophelina. Antennae brown, verticels

 frosty tomentum, dorsally with small flat brown scales, a couple of bristles 

 or long hairs at the apex ; proboscis light brown, covered with very thin 

 flat scales and curved hair-like scales, a few bristles at the base, tip lighter, 

 eyes dark brown ; clypeus light, with frosty tomentum.
