mesonotum. On the centre of the metanotum are two areas extending 

 from the base to the apex ; these are bordered by an area which is 

 dilated in the middle on the outer side ; at the sides at the base is a 

 long curved area, widest below, with two stout keels opposite the 

 spines, the base bearing also stout keels.

STIBULASPIS, gen. nov. 



Scutellum large, roundly narrowed behind, ending in two longish 

 teeth about 3 or 4 times longer than wide ; strongly longitudinally 

 striated throughout. Metanotum with a steep slope, the sides broadly 

 rounded, not tuberculate. Antennae twelve-jointed, the fourth to 

 ninth joints stoutly produced above, the projections longer than 

 thick, gradually narrowed to a sharp point, the apical roundly 

 narrowed at the apex, closely united to the penultimate, which is 

 broader than long and shorter than the preceding ; they are placed 

 well upon the face, above the lower edge of the eyes. Malar space 

 longer than the eyes. Clypeus bounded laterally by oblique furrows, 

 but not from the face. Temples very short. Except on the meta- 

 notum the whole thorax is strongly striated. Abdominal petiole 

 stout, twice longer than wide. Wings not extending much beyond 

 the apex of the abdomen ; the nervures as in Stibula. Legs slender, 

 the femora narrowed towards the apex ; metatarsus as long as the 

 following three joints united. Claws curved, simple. Ovipositor 

 slender. Mandibles curved, bidentate, the apical tooth long, curved, 

 sharp-pointed, the sub-apical shorter and blunter. 



The affinities of this genus are with Stibula, which may be known 

 from it by the antennse in both sexes being simple, neither serrate in 

 the $ nor flabellate in the <? ; and both have a distinct hump-like 

 elevation above the metapleurae. In Stibula, too, the thorax is 

 strongly punctured ; in Stibulaspis it is as strongly striated. The 

 form of the scutellum is the same in both, except that in Stibula the 

 apical teeth are curved, not straight as in the present genus. In the 

 (? of Stibulaspis the abdominal petiole is longer, much longer than 

 in the $ ; the middle joints of the antennse, instead of being stoutly 

 serrate, are stoutly flabellate. 



The history of the Eucharince is interesting. So far as it is known 

 the species are parasites on ants. Cf. Cameron, Manchr. Memoirs, 

 vol. 34, 1890-91, p. 5, where it is stated that Chalcura bedeli,
