Eleven genera and 19 species of the subfamilies discussed in this 

 paper are known from Burma and Lower Siam. In the preparation 

 of this paper 34 specimens from these localities have been studied.

Of the 19 species I have seen specimens of only 10. Of the 21 species 

 of Calopterygma> known from Burma and Lower Siam I had seen 

 17 and studied 233 specimens. Many more specmiens of Caloptery- 

 gina3 have been received from Mr. Earnshaw during the preparation 

 of this paper. Further comment on the relative numbers of speci- 

 mens in the different subfamilies and on the unavoidable mcom- 

 pleteness of this paper is unnecessary. V
