the scutellum, except for a black Hue, widest on the basal half, in the 

 centre, the post-scutellum, an oblique mark, widest on the lower half, 

 on the sides of the metanotum at the apex, the tubercles, the lower half 

 of the mesonotum, and a large mark on the metapleurte, below and 

 touching the keel, yellow. Antennae black, the middle whitish, the 

 apex fuscous, the scape yellow below. The four front legs are pallid 

 yellow, the femora and tibis broadly marked with black behind, the 

 femora tinged with rufous above, the hinder coxas black, broadly yellow 

 at the apex above and more narrowly at the apex below, the trochanters 

 yellow, the basal half of the hinder femora, the apical half, as are also 

 the tarsi, black. Wings hyaline, the stigma fuscous. Abdomen rufous, 

 the petiole and the apical two segments black, the apex of the petiole 

 yellow. ? . Length, 11 mm.

Face and clypeus, except the latter at the sides, punctured ; there 

 is a deep furrow outside the hinder ocelli ; the occiput is sharply mar- 

 gined. Mesonotum punctured, but not very closely or deeply ; the 

 scutellum sparsely punctured. Base of median segment aciculated, 

 the keels indistinct ; the apical three are^ are distinctly defined and 

 closely and coarsely punctured, as is also the spiracular. The centre 

 of the post-petiole is longitudinally punctured ; the gastrocoeli deep, 

 smooth, except for some striae at the base ; the space between is longi- 

 tudinally striated to near the end of the segment. Pleura closely 

 punctured ; the apex of the pro- obliquely and somewhat irregularly 

 striated. Post-petiole strongly punctured throughout, as are also the 

 other abdominal segments. Tarsi longer than usual. The ventral 

 keel extends on to the fifth segment ; the last abdominal segment is 

 bluntly rounded ; the second and third segments, and to a less extent 

 the fourth, are closely striated ; there are seven segments, the last 

 being nearly as large as the preceding. Metanotum short ; the areae, 

 with the exceptioii of the areola, punctured, the basal less strongly 

 than the others ; all the arete, including the petiolar, are distinctly 

 defined. 



Leptothecus, gen. nov. 



Median segment large, distinctly longer than broad, its apex 

 spined, and with a somewhat steep, not rounded, slope ; the areola 

 coffin-shaped, open at the base, elongate, fully three times longer than 

 broad, transverse at the apex. Scutellum flat. Apex of clypeus 

 broadly transverse. Labrum projecting. Antenna broadly ringed 

 with white, not much dilated beyond the middle. Abdominal petiole 

 long and slender, becoming gradually, but not much, wider towards 

 the apex ; there are seven segments ; the last is large, two-thirds of 

 the length of the penultimate ; the sheath of the ovipositor largely 

 projectmg, as long as the apical two segments united ; the ventral fold 

 not defined, Areolet 5-angled, narrowed above ; there is a stump of 

 a nervure on the disco-cubital. Tarsi spinose ; the hinder tibiae nar- 

 rowed at the base. The thorax is longer than usual ; with the head it 

 is as long as the abdomen. The latter becomes gradually narrowed 

 from the base of the fourth segment ; the last two segments are marked 

 with white. Hinder legs much longer than the others.
