well defined, and in others it is quite absent ; the post- 

 medial line may or may not be denticulate, whilst in three 

 examples it is only faintly indicated, and in two others it 

 is entirely eliminated. The secondaries are subject to 

 modification both as regards colour and markings. 



I have a series of fourteen specimens from China and 

 one from Corea, which I believe are referable to 31. grandis ; 

 but as all these examples exhibit constant differential 

 characters from the type of the species and also from var. 

 divergens, I venture to describe the form as — 



var, cuTvata, nov. 



Primaries greyish-brown, reddisli-brown in one example ; venation 

 paler ; antemedial line curved, postmedial nearly straight from 

 costa, but slightly curved inwards before reaching the inner margin ; 

 the space between the lines sometimes suffused with darker. Second- 

 aries more uniformly fuscous than in the type of grandis or var. 

 divercfens. 



In var. curvata neither of the transverse lines are waved 

 or denticulate ; the regularly-cnrved antemedial line is a 

 prominent character. 



Occurs in June and July at Chang-yang, Chia-kou-ho, 

 Wa-shan, and Gensan. 



Distribution. Japan ; Yesso ; Corea ; Central and 

 Western China. 



1048. Mythimna rufijjcnnis. 



Mytliimna rujlpennis, Butl., Ann. and Mag. Nat. Hist., (5) 

 i, p. 79 (1878) ; 111. Typ. Lep. Het., ii, p. 21, pi. xxviii, 

 fig. 6 (1878). 



Leucania semiciretda, Graeser, Berl. Ent. Zeit., 1888, p. 349. 



A fine series from Oiwake in Pryer's collection ; I took 

 a specimen in July at Gensan, and I have received the 

 species from Mr. Manley of Yokohama. An example from 

 Amurland in my collection agrees well with the Japanese 

 specimens. 



Obertluir's figure of "Leucania " inanis (Etud. d'Entom., 

 V, p. 70, pi. iii, fig. 4) does not agree with his description 

 of that insect, as it is without the white markings referred 

 to in the text. The figure, however, seems to represent a 

 worn example of 31. rujipcnnis, and this species frequently 

 has a pale mark at end of the cell. 



Distrihution. Japan ; Amurland.
