236 On the Lejyidojytera of the Isle of Askold. 



Hadena Jankowskii^ Oberth. -^Apamea gemina^ var., 

 Hiibn. 



Nobody who knows the extreme variability of this species 

 can regard M. Oberthiir's form as a distinct species ; we have 

 Em'opean examples rather larger than his figure and agreeing 

 with it in pattern. 



Hadena kosahka, Oberth. Near to H. atripUcis^ but with 

 the white spot of the primaries formed as in H. auriplena 

 {Eurois? auriplena, Wlk.). 



Telesilla malachites, Oberth. = Canna, sp. close to C. 

 pulchripicta. 



Acontia variegata, Oberth. Apparently an Anarta [A. 

 myrtilli group.) 



Acontia flavomaculata, Oberth. Somewhat like " Erastria!^ 

 rubicunda, Wlk., but probably congeneric with the preceding 

 species. 



Erastria nemorum, Oberth. Near to E.fuscula, which is 

 common in Japan. 



Erastria costimacula, Oberth. 



Erastria mandschuriana, Oberth. Belongs to the Lima- 

 codidje. 



We have this beautiful little moth from Tokei ; its colora- 

 tion and the slenderness of its abdomen must have been the 

 only characters which suggested to M. Oberthiir that it be- 

 longed to the Acontiidae ; its short, curled, pectinated antennae 

 (misrepresented by M. Oberthiir's artist) , and the scattered 

 shining scales all over the primaries, as also the banding of 

 these wings beyond the middle, should have guided him to 

 the natural family of the species. I would propose to call this 

 genus Mimerastria, from the somewhat vague resemblance 

 which the species bears to E. candidula, and which has thus 

 misled M. Oberthiir. 



Plusia nadeja, Oberth. ^Plusia zosima,vsiY., Hiibn. 



In the British Museum from Japan ; it attains a consider- 

 ably greater size than the figure, which is very poor : the 

 discal lineand outer border of the secondaries are wholly omitted 

 by the artist ; and the brown patches on the primaries are too 

 pale. If the Japanese form be regarded by M. Oberthiir as 

 distinct (as possibly it may be), I will not deprive him of the 

 pleasure of naming it. 



Plusia esmeralda, Oberth. = Plusia moneta, var., Linn, 

 (teste M. Oberthur). 



Plusia locuples, Oberth. := Plusia ornatissima, Walker. 



This Plusia is fairly common in Japan. 



Amphipyra ohscura, Oberth. = Ampihipyra pyramidea, 

 L. (teste Oberth.).
