Like E. latipes, soror, and auriventris, this has the hind tibia 

 dilated beyond its base, especially in the male. It is smaller than 

 any of those species, of the narrowly elongate form of the first 

 and almost identical in colouring and pattern, the scales being 

 quite dull, except upon the head and legs, where they are silvery, 

 those of the hind tibia included. The longitudinal lines of pale 

 scales upon the elytra are almost entire, and there is an incomplete 

 transverse band just behind the base. The scales of the tibise 

 and tarsi are much narrower than those of E. latipes. 



A second specimen, a female, apparently belonging to the 

 species, is from the Khasi Hills, but the single male bears no 

 precise locality. In the female the longitudinal lines of the elytra 

 are interrupted in the middle.

I have seen females only. The male will no doubt be found to 

 be strikingly different, as is the case with the closely-related 

 E. suturalis De Borre (Plate I. figs. 1 & .3), of which also the 

 female only has hitherto been described. E. oczdicauda (female) 

 is similar in shape and pattern to the latter, but the median 

 stripe, instead of being opaque yellow, is brilliant pale bkie, like 

 the lower surface, and the beautiful golden or silvery-blue scales 

 of the pygidium are contrasted with a black eye-like spot on each 

 side at the base.
