98. Chrysopilus birmanensis, sp. nov. 



Very near C. cochinensis, differing as follows : Head bluish 

 ash-grey, except the centre of the frons, which is of the same 

 shade of brown as in C. cochinensis ; 3rd antennal joint brown, 

 the whitish pubescence rather more conspicuous; occiput with 

 distinct whitish pubescence towards side-margins. Suutellum 

 wholly dead-black, like the thoracic dorsum. Pubescence of 

 abdomen at base of 2nd, 3rd, and 4th segments more golden 

 yellow than whitish. Basal half of anterior femora black. Wing- 

 tip without suffusion; stigma yellowish brown, more diffused, the 

 suffusion not extending below 2nd longitudinal vein. 



Described from a unique $ in the British Museum from 

 G-okteik Gorge, Northern Shan States, Upper Burma, 26. vii. 

 1900 (Col. C. T. Bint/ham). 



This is remarkably like C. cochinensis, and may possibly be a 

 variety of it.
