separated all round. Eyes large, oval ; the malar space as long as the antennal 

 pedicle. Ocelli in a curve ; the hinder separated from each other by double 

 the distance they are from the eyes. Occiput almost transverse. The pro- 

 notum, scutellum, and mesonotum of almost equal length ; there are com- 

 plete parapsidal furrows. 2nd abdominal segment very large, as long as the 

 head and thorax united. Post-marginal vein longer than the stigmal, sub- 

 marginal almost twice the length of the marginal. Legs normal, pilose. 



A genus of Eurytomini easily known by the very large 2nd abdominal 

 segment ; it being, as regards the length in comparison vvith the others, some- 

 what as in the genu? Eunotus. 



Xenopelte couridce, sp. n. 



Black, the legs pallid yellou, the femora and tibiae more or less infuscated, 

 the antennae testaceous ; wings hyaline, the nervures dark testaceous. Female. 

 Length, 1-1.50 mm. 



Bred from galls on leaves of Courida. Head and thorax shining, aci 

 culated, the scutellum finely, closely transversely striated, its apex broadly 

 rounded, and with a distinct margin or keel ; the upper part of the head and 

 thorax covered with a microscopic white pile, which is denser on the meta- 

 thorax. Basal segment of abdomen raised, short, testaceous, the 2nd is finely 

 microscopically punctured ; the apical are sparsely covered with white hair, 

 the ovipositor is moderately broad and shortly projects ; the abdomen is 

 longer than the head and thorax united. 



In one example the coxae and abdomen are fnscous ; this ma) be through 

 irnmaturitv 



Pteromalin;e. 



Mronea gen. nov. 



Antennae 13-jointed, as long as the head and thorax, thickened towards 

 the apex, but not much and gradually so ; placed shortly below the middle 

 of the face and of the eyes, which are large and parallel, neither converging 

 above nor below. Head large, clearly wider than the thorax ; the occiput 

 widely roundly incised. Prothorax small, the apex transverse, raised. Meso- 

 notum short, wider than long, as long as the scutellum, without furrows. 

 Scutellum longer than wide, the apex rounded. Metanotum short, the basal 

 central part finely, closely striated, opaque, this part having a longitudinal 

 oval fovea on the outer edge ; the outer part is smooth, has an oval fovea 

 at the base and a triangular incision at the apex ; the apex is broadly roundly 

 raised in the middle and has a transverse fovea on the sides. Abdomen 

 sessile, shorter than the thorax ; its 2nd segment is longer than the 1st and 

 longer than all the others united ; the ovipositor shortly r projects. The 

 submarginal nervure about one-half longer than the marginal ; the post- 

 marginal one-fourth shorter than the latter and one-third longer than the 

 stigmal vein, which is oblique and dilated at the apex.
