The wings of this species are white, as Oberthiir correctly 

 describes them ; but his figure represents a brownish-tinged 

 insect.

There was one specimen in Prjer's collection, and I took

 have one female from the province of Kwei-chow, taken in 

 July ; this specimen has a ratlier broad border on outer 

 margin of primaries.

Appears to be a common species in Central and Western 

 China. 



Some of the specimens are not separable in any way from 

 more or less typical European examples. The majority, 

 however, although modifications of the form, are referable to 

 trikotaria^ Feld. There are also specimens agreeing with 

 iterata^ Butl., on the one hand, and with nudipennis^ VV^arr., 

 on the other, and the connecting-links between these two 

 forms are represented. 



One specimen of the iterata form was taken by my native 

 collector at Ningpo. 



Var. obsoletaria^ nov. 



Pale brownish grey ; markings, with the exception of 

 discal dots and obscure dark transverse lines, obsolete. 



Four male specimens from How-kow, Thibet : July. 



Distribution. Europe ; Armenia ; Altai ; Siberia ; Amur ; 

 N.W. India ; Central, Western, and North-eastern China j 

 Thibet.
