the lepidopterous genus Euchromia. 115 



25. Euchromia siamensis, Butler. 

 One example only, from Siam. 



In one of his ' Kevisions of Australian Lepidoptera,' 

 Proc. Linn. Soc. N. S. W-, 2nd ser., vol. i. p. 787 (1886), 

 Mr. Meyrick describes what he regards as Euchromia 

 polymena from North Australia. Judging by his descrip- 

 tion of the markings of the primaries, I have no hesita- 

 tion in pronouncing it to be perfectly distinct from the 

 Indian species. As, however, I have not seen the 

 broken specimen from which Mr. Meyrick penned his 

 description, I leave it to him to give it a distinctive 

 name : it probably should stand near the following. 



26. Euchromia semiluna, Walker. 



A very distinct species founded upon a single example, 

 the habitat of which is unknown.
