Judging from the figure alone it appears to us that Moore's type 

 specimen was a female, he described it, however, as a male. It is 

 considerably larger than our male." (Elwes and de Niceville, I. c.) 



This species was originally described by Mr. Moore from a specimen 

 obtained by Limborg at Hatsiega, Upper Tenasserim, and he gives the 

 expanse as i-^ inches, otherwise his description is substantially the same 

 as that quoted but not so detailed. 



I caught a few specimens at Tilin, Yaw District, Upper Burmah, 

 during March, 1890.
