9. E. taishoensis Lewis. 
Laos: Luang Prabang, Xieng Khouang (March—May). 
TONKIN (June). 
A species only recorded hitherto from Japan. 
10. E. indiea Crotch. 
Laos: Luang Prabang, Xieng Khouang, Pou Bia 
(Jan—June). Tonkin: Chapa (June). Burma. Assam. 
SIKKIM, 
The pale yellow markings are a little narrower than in 
Indian specimens, and the humeral spot is a little larger 
in consequence, but I have found no more important 
difference. It is this form which has been described as 
EB. chapwisi, Dohrn. 
11. E. psiloides Bedel. 
Tonkin: Than Moi (June, July). 
Easily recognisable by its conspicuous hairy clothing and 
pale markings. 
12. E. eurvierus Bedel. 
TONKIN. 
I have not seen this species. 
13. Episeapha ambigua, sp. n. 
Nigra, haud nitida, singulo elytro fasciis duabus angustis pallide 
flavis ornato, antica post humerum posita, ad marginem externam 
fere attingenti, et ad marginem basalem connexa, postica ante- 
apicali arcuata, antice quadri-, postice tri-dentata ; elongato-ovalis, 
¢ supra nuda, pedibus antennisque gracilibus, capite et pronoto grosse 
sat crebre punctatis, hujus lateribus bene arcuatis, marginibus sat 
latis, ante medium minute incrassatis; elytris coriaceis, fere opacis, 
convexis, lateribus bene arcuatis; corpore subtus crebre et minute 
punctato, vix perspicue pubescenti; antennarum articulis 2-9 
elongatis, tertio quam quarto haud longiori. 
Long. 16 mm.; lat. max. 6-5 mm.

Laos: Luang Prabang, Sala Pang Yok (March). 
A single specimen only. . 
Although the pattern is almost identical with that of 
E. indica, this is a peculiar and isolated species which, by 
the curvature of the sides of the prothorax and elytra, 
shows an approach to Triplatoma, Trichulus, etc. The 
eyes are larger than in that group of genera, and, with the 
short third antennal joint, determine the true relationship
