of the male are different ; the tooth of upper forceps is more 
distinct, the under forceps are longer, reaching more than 
half the length of the upper pair, the triangular projection 
on the unde:side of the last segment is much elevated and 
covered with black hairs, the pubescence on genitalia black, 
“but at apices chiefly yellow. Scutellum with a few black 
bristles and with many long yellow hairs. Ovipositor of female 
includes the last four segments of abdomen. Moustache of 
stout black bristles with a few long white hairs intermixed 
in the female, in the male the yellow hairs are much more 
numerous and deeper in colour. 
The following species from China are included, though 
they more properly belong to the Palearctic Region, as most 
of them apparently come from North China :— 
Promachus testaceipes, albopilosus, viridiventris, and palli- 
pennis, Macq. Of these the first has legs red, the second 
species has the legs black, but the tibiz testaceous, and is 
white-haired, the third has a shining green abdomen, and the 
fourth has black legs with red tibiz, and might possibly be 
identical with Promachus anicius, Wik. Macquart described 
the type a male, but makes no mention of the tuft of white 
hairs on genitalia. 
Promachus maculipes, Wlik., from Hongkong, should be 
deleted from the list, as the type is apparently lost. 
Two new species of Promachus have been described from 
Formosa by Matshumura, in ‘Thousand Insects of Japan,’ 
Additamenta, ii. pp. 326-328, date not stated :— 
Promachus horishanus, measuring 24 mm.—Abdomen of 
female resembling those of P. complens group, the last five 
segments of abdomen said to be narrow, shining, forming 
the ovipositor presumably, the anterior segments with long 
reddish-brown hairs. Scutellum with fulvous and black 
bristles. Legs fuscous with yellow and black hairs. 
Promachus formosanus, measuring 21 mm.—Male with a 
white tuft to genitalia. Abdomen brown, according to 
figure of male with lighter bands. Legs black, tibie pale 
fulvous. Scutellum with long black bristles.
