258 THE ENTOBIOLOGIST. 



Dr. Durham sends me the following note concerning this 

 species : — " Sunday, Jan. 18th, 1903. Larvae and pupae collected 

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

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

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

 dipping well since abandoned, about four feet in diameter, and 

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

 where Culcx mimeticus larvae had been caught. Numerous small 

 dark AnojjJieles -like larvae, which all died before transforming ; 

 there were also some quite minute pupae. Only two hatched out. 

 The long-palped species sat a la Anopheline at an angle."

 largest, with three small spots beneath ; most of the veins pale scaled,

 snowy-white spindle-shaped scales and some browu ones projecting

 with small flat and narrow-curved white scales. Wings ornamented 

 much as in xV. stephend, but the fourth black spot on the first long

 also more dark scales on the branches of the first submarginal cell, 

 and three (not two) spots on the upper branch of the fifth vein. Legs 

 brown ; the fore pair with apical pale bands to the metatarsi and first 

 two tarsi, and a white apical spot to the tibiae ; ungues unequal, the
