Acleris schalleriana aberration viburnana (in part). — Obraztsov, 1956, Tijdschr. 

 Ent., vol. 99, p. 134. 



McDunnough (1934) found that the North American specimens 

 of schalleriana do not differ in any marked respect from the European 

 forms of this species, the variation of which is sho^vn in Kennel's 

 (1908, pi. 4, figs. 34-38) figures. A large series of moths of this 

 species from North America, examined by the present author and 

 compared with the European specimens, has distinctly sho^vn that 

 the variation of schalleriana is quite distinct in both parts of the 

 Holarctic region, and the Nearctic population deserves a separation 

 as a subspecies. The form viburnana, which is predominant in 

 North America, although it reminds one somewhat of the European 

 form. Jalsana Hiibner (gennarana Frolich), differs from it in having 

 the forewings more elongate, with the ground color from pearl gray to 

 deep grayish ochreous and markings darker. Especially typical of 

 viburnana is the tendency of the costal spot of forewings to divide 

 and form a separate middle fascia and a comparatively small outer 

 part of costal spot between this fascia and the wing apex. This 

 small fragment of the costal spot is usually connected with the tornus 

 by a fine line. In the true falsana, not yet known from North America, 

 the middle fascia can be observed rather as an exception, although 

 it is common in the form plu7nbosana Haworth, known from both 

 Europe and North America. In this latter form, synonymous with 

 jamula Zeller, the forewings are more rotundate, more or less shaded 

 with yellowish externad. The North American specimens of schal- 

 leriana forewings darkened and markings indistinct, might be identi- 

 fied with the form castaneana Haworth, although there is some 

 difference between them and the European specimens of this form. 

 The latter have no markings at all because the markings of the 

 Em'opean specimens of schalleriana are considerably paler than those 

 of the North American viburnana, and they are thus not seen on a 

 dark ground.
