A specimen taken by Smith at Khun Tan, October 27, 1929, has 

 been examined by Dr. Ticehurst, who writes : "Seems to be (small $ ) 

 assamensis." Nine males and one female (all in poor condition), 

 collected by Griswold at the summit of Doi Ang Ka, March 22-30, 

 1937, are also called assamensis by Ticehurst, with the qualifying re- 

 mark : "I cannot make anything else of them." In addition, a male 

 from Doi Suthep, 2,700 feet, January 18, 1936, and a female from 

 Chiang Saen Kao, January 12, 1937, are identified by the same au- 

 thority as P. r. assamensis > claudiae.
