188 en M‘Lachlan on th 
the head and thorax are nearly wholly blackish above). 
Legs yellowish; wings with a slight testaceous tinge, 
and with fuscous veins; there is a very narrow pale 
fuscous fascia beyond the middle, expanding on the costa, 
where it forms the inner side of the pterostigma (in the 
posterior wings this fascia is abbreviated or interrupted), 
and (in the ¢ ) two or three small basal spots; posterior edge 
of the 5th abdominal segment in the ¢ blackish ; terminal 
segments yellowish ; 6th and 7th segments each nearly as 
long as all the basal segments united ; the apical portion 
eradually incrassate ; footstalk of the cheliferous segment 
cone shorter and of the same form; its apex con- 
siderably dilated, so that the basal portion (before the 
claws) is somewhat pyriform ; claws long, strongly curved 
and crossing ; appendages very long and slender, extending 
beyond the base of the claws. (in the @ the terminal 
segments of the abdomen are very slender.) 
Total length of body of $ about 25 mm.; expanse 
25 mm. 
One pair (é, ¢) in the Leyden Museum; captured by 
Von Siebold.

Head deep black, pale posteriorly ; rostrum piceous, 
with pale sides. Thorax piceous in front, testaceous 
posteriorly, wholly yellow beneath. Abdomen fuscescent. 
Legs yellow. Wings with a slight greyish tinge, and 
with fuscous veins; the only marking is a mather broad 
pale fuliginous apical space, straight internally ( ). 
Expanse 24 mm. 
Two females in the Ley den Museum; captured by 
Von Siebold., 
An approach towards the abdominal formation in the 
3 of Leptopanorpa is to be found in P. nematogaster, 
M‘Lach., from Java (perhaps also in P. Charpentier?, 
Burm.), but in it the cheliferous terminal segment is sessile, 
The genus very clearly shows that the abdomen in the 
Panorpide has nine segments; for the Ist segment, ordi- 
narily confused with the hinder portion of the meta- 
thorax, is here very long. 
PANORPODES, gen. nov. 
General form much as in Panorpa. In the ¢ the 
abdomen is short; all the segments (excepting the terminal
