460 Mr. J. H. Leech on Lepidoptera Heterocera 



captured some fine examples at Nagahama and Gensan in 

 July. I have also received the species from several Chinese 

 localities. 



Distribution. Japan ; Corea ; Amur ; Central and Western 

 China. 



The very extensive series that I have retained comprises 

 all the intergrades between a specimen which is white in 

 ground-colour, with narrow black bands, and one which is 

 black in colour, with three small white spots on the basal 

 area and two spots, rather larger, on the outer third of 

 primaries. The secondaries of this specimen are black, with 

 two white bands. 



Genus NEOLYTHRIA. 

 (Alph. Rom. sur L6p. vi. p. 72 (1892).) 



NeolytJiria djrouchiaria. 



Abraxas djrouchiaria, Oberth. Etud. d'Entom. xviii. p. 34, pi. iii. fig. 37 

 (1893). 



I received a number of specimens from Ta-chien-lu, Moupin, 

 and Che-tou. In some of these the black transverse band of 

 primaries is not intersected by a yellow line. 



Var. montana, nov. (PI. VII. fig. 11.) 



Smaller than the type ; the transverse band of primaries is 

 broader, the black spots on outer margin of each wing are 

 united and form a marginal band, the secondaries have a 

 distinct macular submarginal band. 



A long series was taken on the summit of Mount Omei in 

 August. 



In one female example of this form the ground of primaries 

 is yellowish, and the secondaries are tinged with the same 

 colour. 



Hob. Western China. 



NeolytJiria abraxaria. 



Neolythria abraxaria, Alph. Rom. sur L6p. vi. p. 72, pi. iii. figs. 8 a, b 

 (1892). 



This species was first discovered in the province of 

 Szechuen. The specimens I have received from Western 

 China do not agree with the type ; I therefore describe them 

 as var. confinaria, nov. 



In this form the white submarginal band on primaries is 

 much narrower and its edges are serrated ; the lower discal 

 streak is shorter, and there is sometimes a small triangular
