440 Mr. J. H. Leech on Lepidoptera Heterocera 



from N. China, and there are specimens in the National 

 Collection at South Kensington from Yokohama, Hakone, 

 Tokio, and Ashi-no-yo. 



The specimens from Oiwake differ from the typical form in 

 having the ground-colour of primaries and basal area of 

 secondaries whiter, and for this form I propose the varietal 

 name pallidaria. 



Distribution. Japan ; Central and Northern China. 



Arichanna GascJikevitchii. 

 Boarmia Gaschkevitchii, Motsch. Bull. Mosc. xxxix. p. 197 (1866). 



Probably this species is identical with Arichanna (Rhy- 

 paria) jaguar aria, Guen. 



Arichanna flavomarginaria. 



Ithypariajlavomarginariay Brem. Lep. Ost-Sib. p. 83, pi. vii. fig. 11 



(1864). 



Abraxas flavomarginaria, Graeser, Berl. ent. Zeit. 1888, p. 390. 

 Diastictis flavomarginaria, Meyrick, Trans. Ent. Soc. Lond. 1892, p. 104. 



Several specimens were captured by my native collector at 



Gensan in July. I have also received the species from Chang- 



r ang, Moupin, and the province of Kwei-chow : June and 



Distribution. East Siberia ; Amur ; Corea ; Central and 

 Western China. 



The specimens in my series exhibit considerable variation 

 in the size, number, and intensity of the black markings. 



Genus EREBOMORPHA. 



(Walk. Cat. Lep. Het. xxi. p. 494 (I860).) 



Erebomorpha consors. 



Erebomorpha consors, Butl. 111. Typ. Lep. Het. ii. p. 52, pi. xxxvii. 



fig. 3 (1878). 

 Mesastrape consors, Warren, Novit. Zool. i. p. 432 (1894). 



A few specimens from Fujisan and Nikko in Fryer's 

 collection. 



My native collector obtained the species at Hakodate in 

 June or July, and there are specimens in the National Col- 

 lection from Yokohama and Tokio. I have also received 

 examples from Moupin and Chang-yang, July. 



Distribution. Japan ; Yesso ; Western and Central China. 



Some of the Chinese specimens appear to be intermediate 

 between E. consors , Butl., and E.fulgurita, Walk.
