of the male are different; the tootli of upper forceps is more 

 distiller, tlie under forceps are longer, reaching more than 

 halt" tlie lengtli ot" the upper pair, the triangular projection 

 on the nndeiside of the last segment is much elevated and

 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 Paljearctic Region, as most 

 of them apparently come from North China : — 



Promachus testaceipes, albopilosus, viridiventris, and palli- 

 peiinis, Macq. Of these the first has legs red, the second 

 species has the legs black, but the tibicC testaceous, and is 

 white-haired, the third has a shining green abdomen, and the 

 fourth has black legs with red tibiai, and might possibly be 

 identical with Promachus anicius, Wlk. Macquart described 

 the type a male, but makes no mention of the tuft of white 

 Lairs on genitalia. 



Promachus macuUpes, Wlk., 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 jNIatshumura, 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 forinosanus, measuring 21 mm. — Male with a 

 white tuft to genitalia. Abdomen brown, according to 

 fi<rure of male with lighter bands. Legs black, tibiae pale 

 fulvous. Scutellum with long black bristles.
