Diloha, St., ccenileocephala, L. 

 Var. armena, Stdgr. — Dr. Staudinger, in his ' Catalog,' de- 

 scribes a variety under this name as "much paler; anterior 

 wings cinereous." I have not seen this form. The locality he 

 gives is Armenia. 



Arsilonche, Ld., albovenosa, Goze {venosa, Bkh.). 



The type of this species, as its name indicates, has white 

 nervures, which show distinctly on the pale wainscot ground 

 colour. The depth of the ground colour varies from pure silvery 

 white to deep (inclining to reddish) ochreous. A great deal of 

 difference exists in the development of the dark shades under 

 the base of, and above the outer half of the median nervure, 

 and towards the apex. Mr. "VVarren, of Cambridge, informs me 

 that it is "the specimens of the second (autumnal brood) which 

 have the dark dashes more prominently marked, and the fore 

 wings sometimes more thickly peppered," This form (with the 

 dark shades clearly developed) is figured by Hiibner (fig. 380) 

 under the name of derjener. 



a. var. centriimncta, H.-S. — The anterior wings of this variety 

 have a black spot in the centre of each wing. The description 

 Dr. Staudinger gives is *' alse anteriores puncto nigro." This 

 form has, I believe, at the present time only been recorded from 

 Russia, but some of my specimens from Cambridge have this 

 spot faintly indicated. I should not be surprised to learn that 

 this variety exists in some of our collections. 



/3. var. ochracea, mihi. — The ground colour of this variety is 

 reddish ochreous, and the wing-rays pale ochreous instead of
