The latter species, recently described (Tijd. v. Ent. li, 226, 
2 , 1908), from Papua, is distinguished from ortentalis by the pale 
yellow veins, which seems at best a very slender character.

Types of the first three species in Amsterdam Museum, 
type of the last one in the Hungarian Museum. 
I have myself described a new species from Darjiling, E. 
vufoscuteliatus, # (Rec. Ind. Mus. ix, 269, &, pl. xiv, 13). 
I had anticipated drawing up a table of oriental species in 
this genus, but from the descriptions only this is quite impracti- 
cable, the species being very closely allied, whilst the few charac- 
ters that appear most useful taxonomically, viz. the width and 
shape of the frons, the structure of the hind tarsi and the degree of 
pubescence or bareness of the eyes, are ignored by all the older 
writers. ‘The presence or absence of an infuscation at the wing 
tip, the intensity or entire absence of the pale stripes on the thorax, 
and the proportion of tawny colour in the legs are all characters 
subject to considerable variation. 
It is probable that my nepalensis will sink to synonymy, but 
it is not certain which species it is identical with, as three or four 
appear very closely allied if allowances for variation are made. 
These are macrocerus, W., aurifrons, W., (sblendens, W.), nicobaren- 
sis, Sch., and niveipes, Meij. Specimens agreeing with the descrip- 
tion of my nepalensis are in the Indian Museum from Mergui, Mar- 
gherita, Pallode and Travancore, 15-xi-o8 [Annandale], these 
being four males, and from Mergui, Nepal (the type specimen of
