 specimens withuul ocelli. Tims, a female I'rom (Jliefoo has only two 

 more or less interrupted uhilish streaks on each si(h'. l)ordered by 

 larger dark brown spots, and a male from the same locality resembles 

 very closely the type oi E. hreiK-lilriji in its coloration, a, continuous 

 white streak extending from below the eve to the L;roin, edged above 

 by a dark brown baml, which is continued on the tail; a second 

 (dorsolateral) white streak above, continuous on the neck, broken np 

 into occUar spots on the body. Other specimens are intermediate 

 between these striated examples and the more frequent type with 

 nothing but ocelli. Lower parts white.

The sexes are difficult to recognize externally in this species. The 

 males have a larger heail and a rather shorter body, but the tail 

 is not or but scarcely swollen at the base and the femoral pores are 

 not larger than in the females. 



Habitat. — Manchuria, Corea, Mongolia, Northern China.

Only about a dozen specimens of this form an^, known to exist in 

 collections, and it is therefore difficult to decide whether it should 

 rank as a variety of E. anjii'^ or as a distinct species. Considering 

 the characters which have been adduced in favour of its specific dis- 

 tinction as either too slight or as occurring also in annectant specimens 

 of E. argus, I prefer, hn- the present, to treat it as a variety. 



The latest definition is that given l)y Bedriaga (I.e.), and is here 

 repeated, the structural characters from his synopsis (p. 5U5), the 

 coloration from his diagnoses (pp. G4o and 655j : —
