the scape slightly darker coloured than the flagellum. Temples slightly 

 dilated from the base to the apex. 



This species comes close to V. hicolor, but the colour is darker, 

 more rufous, without any yellow tint ; it is much larger and more 

 robust ; in hicolor the antennae are black above, the upper part of 

 the front, the vertex entirely, and the occiput are black ; the 

 frontal mark is transverse above, the clypeus is longer compared 

 with its width, and the incision on its apes is deeper ; the wings 

 are clearer, more hyaline, and the pubescence darker. In the 

 ground colour my species more resembles auraria, but that 

 species is smaller, wants the black frontal mark, has the thorax 

 for the greater part blackish, and the four hinder legs for the 

 greater part black ; also there is no yellow tinge on it. 



Vespa flavo-fasciata, sp. nov. 

 Head orauge-yellow ; the occiput, except round the edges, a mark 

 ou the ocellar region, extending from shortly behind the ocelli, half- 

 way down the front, the mark roundly narrowed before and behind ; 

 it is thickly covered with long blackish hair. Clypeus closely and 

 strongly punctured, its apex roundly but not deeply incised ; the sides 

 are more deeply incised. Mandibles coloured like the head, with the 

 teeth black. Frontal plate broadly rounded at the apex and furrowed 

 down the middle. Thorax deep black, the pronotum dark rufous ; the 

 whole thorax is thickly covered with long dark fuscous hair. Abdomen 

 sparsely covered with longish hair ; the basal slope of the first segment 

 black, the rest brown, darker on the apical half; the apex with a 

 narrow yellow line ; the basal two-thirds of the second brown, darker 

 at the base, the apex slightly dilated in the middle ; the base of the 

 third is similarly coloured to shortly beyond the middle ; the middle 

 of the black band is produced to the base of the apical third, is 

 obliquely narrowed, and has a rounded point on either side of the 

 dilated middle, the rest being yellow ; the other segments yellow, 

 except that the fourth and fifth are narrowly brownish at the base, 

 with a rounded projection on the sides ; the second to fourth ventral 

 segments are yellow at the sides, the blackish basal part projecting 

 there as irregularly rounded knobs ; the last segment is entirely yellow. 

 Legs black, the apex of femora, tibise, and tarsi dark testaceous ; the 

 hair on the femora is long and black. Antennae dark rufous. Wings 

 hyaline, darker in the costal cellule ; the nervures dark testaceous. 

 Tegula3 dark testaceous. ? . Length, 24 mm. 



Hah. Niigata (Shinanogawa). 



Comes near to V. crahroiiiformis, Sm., and V. mongolica, 

 Andre. It has also some affinity with V. crahro. 



Mr. Lewis has taken some specimens of a wasp which is 

 clearly V. japonica, Saussure, non Sm. non Had. This is the 

 species. Col. Bingham tells me, which Smith (Trans. Ent. Soc. 

 1873, p. 198) quotes as V. leivisii, Saus. MS. Vesjpa japonica, 

 Ead., is identical with mandarinia, Sm. Smith's japonica I do 

 not know, and the name is not admissible, it being later than
