0. Arenostola unicolor s]>cc. nov. 



Staudinger, followed by Spuler and Hampson, refers the insects here treated 

 of, taken at Tura, Issyk-Kul and Amdo, to lAragmilidh Hbn. ; the insect which 

 I call unicolor, of which there are in the Tring Museum .5 ? ? taken in the Tedschen 

 Oasis, Transcaspia, is slightly larger and broader-winged than European phrag- 

 mitidis, agreeing in its pale coloration with the ab. pallida Tutt, but, while the 

 fringe is always grey-brown in phragmitidis, in unicolor it is concolorous with 

 the wing ; secondly, in phragmitidis the hindwing is always grey with paler veins 

 and the fringe pale ; in unicolor the hindwing is pale ochreoas like the fringe.
