area, widened at the base ; on the sides at the base is a large semi- 

 circular area; below it, bordering the central area, 2 smaller ones, 

 wider than long, rounded on the outerside. Metapleurœ irregu-

 longitudinally striated. Antennse 51- jointed, the fiagellum densely 

 covered with short stiff black hair. 



ICHNEUMONIN.E. 



Platylabus spilonotus sp. n. — Black, the clypeus whitish 

 yellow, the yellow above inside, below extending outside the foveae, 

 the mark being thus wider below than above; the palpi similarly 

 coloured; mandibles to near the apex testaceous, an oval mark in 

 the centre of the mesonotum near the apex, the greater part of the 

 scutellum, the lower part of the mesopleurae from shortly below 

 the middle, the mark narrowed at the base, the apex, narrowly 

 below, more broadly, roundly above, the metapleurœ from the keel, 

 the apex of metanotum, the mark continued from the top of the 

 slope in the middle to the areola, the projection narrowed gra- 

 dually above, pale rufous. The apex of the 2 nd and 3 rd abdominal 

 segments narrowly whitish yellow. Legs black, the 4 front coxœ 

 and trochanters whitish yellow, the underside of the 4 front femora 

 lined with darker yellow, the tibise in front of a still darker 

 yellow; the apex of the hind coxae very narrowly, the underside of 

 the trochanters yellow; the apical 4 ltl of the basai joint of the hind 

 tarsi and the whole of the others white. Wings hyaline, the stigma 

 and nervures black, the areolet 4-angled, the récurrent nervure is 

 received near the apex of the basai third; the disco-cubital nervure 

 is broken by a minute stump; the nervellus is shortly postfurcal. 

 Antennae serrate, more strongly so towards the apex Uian in the 

 centre. Hind legs longer than usual. cf.

Mayumbe (Deleval). 



Talimeda gen. nov. — Scutellum flat, not much raised above 

 the mesonotum, the sides ?toutly keeled from the base to the apex, 

 which has a long, steep slope, margined by a narrower keel. Are- 

 ola large, horse-shoeshaped, extending from the base to the top of 

 the apical slope, the keel stronger on the rounded base ; there are 

 no other areae, but the sides, including the basai slope, are mar- 

 gined by a keel, which curves shortly inwardly on the top of the 

 apical slope, and is thickened there, but not forming a tooth ; 

 there are indications of 2 keels down the middle, top half of the 

 apical slope; the spiracles are linear,about3 times longer than wide.
