spots; sometimes the verleliial line is lighter than the rest of the 

 ground-colour, whicli varies Ironi buff to grey. There are also 

 specimens without ocelli. Thus, a. female from Cliefoo has only two 

 more or less interrupted whitish slrealcs on each side. Imrdered by 

 larger dai'k brown spols. and a mali' from the same locality resembles 

 very closely the type of I'!. Iim/rlilii/i in its coloration, a continuous 

 white streak e.\tcndiug from below the eve to the groin, edged above 

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

 (dorsolateral) white streak al/ove, continuoLis on the neck, broken up 

 into ocellar spots on the body. Other specimens are intermediate 

 between the.se striated examples and the more fre<pient type with 

 nothing but ocelli. Lower parts white. 

 Measurements (in millimetres) : 



The sexes are dittii/ult to recognize externally in this species. The 

 males have a lai-gcr head and a luther shorter Ijody, but the tail 

 is not or but srarccly 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 foi-m are known to e.xi.st in 

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

 rank as a variety of E. arjus or as a distinct sjiecies. Considering 

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

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

 of E. argnu, I prefer, for the present, to treat it as a variety. 



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

 repeated, the structural characters from his synopsis (p. 6U5j, the 

 coloration from his diagnoses (pp. (346 and 655) : —
