1 January, 



wings broad, pale grey brown or pale reddish bi'own ; basal patch dark bi*o\vn 

 but only visible on the dorsal margin, where its outer edge is angvilated and 

 outlined with deep black brown ; this is followed on the dorsal margin by a 

 white forked blotch, the two forks being oblique in opposite directions and out- 

 lined with silvery white ; the inner and lai'ger branch is constricted at the middle 

 of the wing, and the apex contains a dark brown horizontal streak or a dot ; both 

 branches are more or less filled in with steel blue grey ; central band dark rich 

 brown, oblique, narrow on the costa, its outer margin sharply indented and out- 

 lined with i)ure silvery white ; the apical area contains a rounded dark brown 

 patch ; the costal streaks, gemminated yellowish white, are continued round the 

 apical patch ; cilia brown tipped with white. Hind-wings smoky brown. Female 

 similar, rather stouter, the markings and hind-wings darker. 



This species unlike pro/undana seems to be quite constant. 



^ genitalia. Valva long, curved, costa angulated, spines denser towards 

 the base ; sacculus not free, long, before reaching the spines it is truncate, the 

 apex set with a patch of fine spines, outer margin rounded towards the base ; 

 uncus not pi'oduced, rounded; socii long, slender, drooping, in-curved; aedoeagus 

 cardinate ; saccus small, ctu-ved. 



$ genitalia. Lobes of ovipositor rather narrow ; ostium with narrow 

 rounded plate on either side, set with fine hairs ; biirsa sub-globular, with two 

 deep, long, ctirved signa.

This species, the name for which has been suggested by Mr. E. P. 

 Studd, has been bred by him for a number of years in succession 

 from larvae found feeding upoji old apple trees, and once upon oak at 

 Oxton, S. Devon. He reports that it is confined to these particular 

 trees and is therefore extremely local, that it is absolutely constant, 

 and that profundana is rare in the district. Mr. Studd has long been 

 of the opinion that it was a distinct species, but Mr. E. E. Bankes 

 coiisidered that it was only a food form of profundana. However, the 

 structure of the genitalia, which is perfectly distinct from that of 

 profundana, proves it to be a good species. It has also been taken by 

 the late Dr. Eiding at Buckerell, Devon. 



Such a striking form may possibly have received a varietal name. 

 If this is the case, the name now suggested will fall and the varietal 

 name become specific.
