obliquely on the lowerside to the apex of the mesopleurae, where 

 it is narrowed below at the apex, a mark below the hind wing and 

 a mark, longer than broad, and narrowest behind, on the apex of 

 the metapleurge, and the apices of the basal 4 abdominal segments 

 narrowly, yellow. Legs coloured like the body, the fore coxae and 

 ti'ochanters, the greater part of the outerside and the apex below 

 of the middle coxae, yellow. Wings clear hyaline, the apex 

 smoky ; pedicle of areolet about twice the length of the inner lower 

 nervure. Sutures of thorax black ; the parts at the base and sides 

 of scutellum, a transverse mark on the apex of the metanotum in 

 the centre ; the apex of the pro- and base of mesopleurae, the top 

 of the latter more broadly, the line dilated downwards near the 

 apex, the pleural and sternal sutures, black. Head and thorax 

 closely and distinctly punctured. The traneverse median nervure 

 is received very shortly beyond the transverse basal, almost inter- 

 stitial. The metathorax is more strongly punctured than the rest 

 of the thorax ; the hind tarsi are black. Mandibles black, the 

 base broadly white. The amount of black and yellow on the head 

 and thorax probably varies. 



Metopius erythroinis, sp. nov. 



Black ; the head, except the occiput, yellow, suffused with 

 red ; the edge of the pronotum broadly, a large mark, rounded 

 behind and below on the base of the mesopleurae, scutellum, its 

 keels, the sides of the apical slope of the metanotum and the apex 

 of the metapleuraj, red, as are also the sides and apex of the 1st 

 abdominal segment, and the two apical entn-elj^ ; the apices of the 

 2nd, 3rd, 4th, and 5th segments yellow, the lines narrowed in the 

 middle ; legs red, the front coxae black ; wings hyaline, the apical 

 half of the radial cellule and the whole of the 3rd cubital fuscous- 

 violaceous. Female. 



Length 12 mm. 



Clypeus closely punctured, its tops and sides depressed, its 

 apex broadly rounded ; labrum pale yellow, smooth. Mandibles 

 red, black at apex. Palpi red. Thorax closely punctured ; a 

 smooth shining spot on the sides of the metanotum and on the 

 upper part of the apex of the mesopleurae. Scutellum sparselj- 

 punctured, the punctures large ; its lateral keels large, roundly 

 curved, largely projecting beyond the central part of the apex, 

 which is almost transverse. Post-scutellum closely punctured. On 

 the centre of the metanotum are two curved keels ; on the apical 

 slope are two straight, less widely separated, keels ; on either side
