being black, and the metanotal arese are différent, the areola being, 

 e. g., shorter and wider and inore distinctly bounded by the keels, 

 which form a triangle in iridipennis. 



It may be useful to give a generic description of Xanthomicrodus 

 from the Congo example hère described. 



Head seen from the front broad, not narrowed below; the malar 

 space distinct, about one fourth of the length of the eyes; 2 keels 

 run from the ocelli to the antennse. Sides of scutellum margined, 

 the keels becoming stouter towards the apex, where they unité. 

 Metanotnm areolated, the basai half with 3 arese inside the spiracles, 

 the apical with 6; the spiracles about two-and a half times longer 

 than vvide. Abdominal pétiole about 4 times longer than it is wide at 

 the apex; the ovipositor short, broad. Legs normal; the hind coxse 

 as long as the l st and two-thirds of the 2 11 ' 1 abdominal segments; the 

 middle spur two-thirds of the length of the metatarsus; the hinder 

 about one third shorter; claws cleft. Antennse slightly longer than 

 the body, not tapering mue h towards the apex. Radial cellule 

 narrow, not reaching to the apex of the wing; the l st cubital and 

 discoidal cellules not separated, the areolet 4-angled, narrowed in 

 front. 



There is no mesosternal furrow, but there is a crenulated band 

 under the raised upper part of the mesopleurse. The 3 rd joint of the 

 antennse is shorter than the 4 th . Palpi moderately long. 



In Szkpligeti's System (Gen. Ins,Bracon.Agathinœ, 117), thisgenus 

 would run to Megagthis Kriech., which differs from it in the head in 

 front forming a triangle, there is no plate between the antennse, the 

 scutellum is not margined and the ovipositor is long. At p. 116, 

 l. c, Szépligeti states that thel st cubital and the discoidal cellule are 

 not separated; in the fuller description on p. 122, that they are sepa- 

 rated . 



GARDIOCHILIN^E. 



Gardiochelis bifoveatus sp. n. — Dark rufous, the antennse, 

 centre of front broadly, the vertex, middle lobe of mesonotum, more 

 than the outer half of the latéral and the trophi, black ; legs coloured 

 like the body, but darker, and, more particularly, the hinder 

 femora, the hind tarsi being also blackish; wings fuscous, slightly 

 paler at the base, the stigma and nervures black. There is only one 

 closed area on the metanotum ; it is shortly appendiculated at the 

 base, then becomes gradually widened into a triangle, then gradually 

 narrowed into a larger triangle, which reaches to the apex. The 

 antennse are over 40-jointed.
