178 Mr. R. M‘Lachlan on the 
branches, and many of the nervules starting from it, mar- 
gined with pale yellow; the region of the cubiti is occu- 
pied by a rich yellow streak, deeply furcate from the point 
where the lower cubitus divides, many of the nervules 
between the branches of the fork being margined with the 
same colour: pterostigma darker brown ( ? ). 
Length of body 23 mm.; expanse 59 mm. Greatest 
breadth of posterior wing 9 mm, 
One ? in the Leyden Museum; collected by Von Sie-~

retained, 
A true Ascalaphus, in form resembling A. sibiricus, 
Ey., but differing greatly in coloration. The individual 
before me appears to be highly mature, so that, in all 
probability, the posterior wings in less adult examples will 
be found to be less darkly coloured.

Ascal. subjacens, Walk., Cat. Brit. Mus., Neurop. 431; 
HI, subjacens, M‘Uach., Journ. Linn. Soce., Zool. 
xi. 267; A. remotus, Walk., 1. c. 447. 
Tn all collections received from Japan, and apparently 
common. Occurs also in North China and the Island of 
Formosa. 
The amount of tinting of the wings varies considerably, 
probably according to degrees of maturity. Sometimes 
the wings are wholly vitreous (always excepting the large 
black pterostigma), or they may be vitreous with the 
post-stigmatical area smoky, or wholly pale smoky-brown. 
The type of A. remotus, Walker, placed by him in the 
division of Ascalauphide in which the eyes are entire, is 
only an example of this species with one division of the 
eyes removed.
