124. APISA CANESCENS. 



Apisa canescens, Walker, Lep. Het. iv. p. 917 (1855). 



Camp near 119 miles inland from Mombasa, 7th July, 1897. 



The single female example is smaller than any example of that 

 sex which I have hitherto seen, but we have no East-African speci- 

 mens obtained further north than Natal. It is just possible that 

 this may be a small race of the species, as Sir George Hampson 

 informs me that he has seen a male from East Africa still smaller 

 than the female now received. 



125. ETTCHROMIA AMCEWA. 



Euchromia amoena, Moeschler, Stett. ent. Zeit. xxxiii. p. 350 

 (1872). 



Mayera, 17th July ; Taru, 20th December, 1896. 



This is the species which I called E. africana ; Herr Moeschler 

 erroneously gave Silhet as its habitat.
