roundly curved backwards in the middle ; near the apex is,. 

 on either side, another keel ; and on the apex in the middle 

 are two short oblique ones. The apical furrow on the meso- 

 pleura is stoutly crenulated ; the central furrow on the meso- 

 sternum is smooth. Wings hyaline, with a slight fulvous 

 tinge ; the nervures and stigma black, the latter fuscous on 

 lower side; areolet oblique, almost appendiculated ; the 

 second transverse cubital nervure longer than the first ; the 

 recurrent nervure is almost united to it. Legs entirely 

 ferruginous ; the hinder tibiae darker, almost fuscous in 

 colour. Abdomen ferruginous ; the narrowed basal part of 

 the petiole black ; the basal ventral segments (beyond the 

 petiole) yellow, the apical black. 



Lissonota rubriplagiata, sp. nov. 



Rufa, capite thoraceque flavc-maculatis ; metanoto petio- 

 loque late nigris ; alis hyalinis, stigmate fusco, nervis 

 nigris. ? . 



Long., fere 9 mm. ; terebra, 7 mm. 



Antennas black, almost glabrous. Head rufous ; the eye- 

 orbits all round, more broadly on the inner than on the 

 outer side and below extending to the mandibles, the 

 clypeus, except at the apex, and the base of the mandibles 

 broadly lemon-yellow; the occiput, the ocellar region, and 

 the front, except at the orbits and near the ocelli, black. 

 Vertex minutely and closely punctured ; the front closely 

 transversely striated ; on its upper half is a shallow longi- 

 tudinal furrow. There is a black patch above the sides of 

 the clypeus ; the mandibles are broadly yellow, the teeth 

 black, the part behind them rufous ; palpi black. Thorax 

 rufous ; the middle of the mesonotum between the yellow 

 lines, the sides of the scutellum, the part bordering the 

 post-scutellum, a broad mark on the metanotum roundly 

 narrowed towards the apex and not reaching to the edge 

 of the slope, the middle of the propleurae, an oblique mark 

 on the base of the mesopleurae between tubercles, and 

 the lower yellow mark and the oblique slope of the base of 

 the mesosternum, black. On the mesonotum are two yellow 

 lines, dilated outwardly at the base and extending shortly 

 beyond the middle. A mark on the base of the scutellum 

 triangularly incised in the middle, the post-scutellum, the 

 lower third of the propleurae, a mark on the top in front of 

 the tegulae, a triangular mark under the hind wings, a mark 

 narrowed at the apex on the lower side of the mesopleurae at 

 the base, and a large oblique mark of equal width throughout, 

 and extending from the base to the apex on the rnetapleurae, 

 lemon-yellow. Legs rufous ; the middle coxae entirely and a 

 large mark on the hinder pair narrowed at the apex lemon-
