the eyes ; the greater part of the lateral lobes of mesonotum and of pleurae and 

 abdomen fuscous ; the metanotum, metapleurae, and basal third of the abdomen dark 

 testaceous. Legs white, a line on hinder femora, base of hinder tibiae, a broad line 

 in middle and base of tarsi fuscous. Wings hyaline, costa testaceous ; stigma fuscous, 

 paler at base. Antennae longer than the body, fuscous at apex, and the other joints 

 have a fuscous ring at apex. Head and mesonotum smooth, shining, impunctate ; the 

 head with a few longish scattered hairs ; metanotum with an indistinct central carina, 

 which bifurcates towards the middle of metanotum in two branches, which turn to the 

 side ; hinder half of metanotum slightly rugose, and sparsely covered with white hairs. 

 The first and second abdominal segments are coarsely constricted longitudinally ; on 

 the extreme edge of first is a distinct keel, and from the base there run two central 

 keels, which get lost in the striations in the middle of the segment ; the basal half of 

 the space enclosed by these keels is smooth, shining, not striated. The rest of the 

 abdomen is smooth, shining, impunctate. The male has the antennae longer (distinctly 

 longer than the body), the metanotum and base of abdomen darker ; the fuscous ring 

 on hinder tibiae is shorter, and the tarsi have only the apical joints fuscous. (Cameron.)

%. Length i '5 to i 6 mm. Apterous, or at most with small, scale-like wing pads ; 

 ovipositor prominent, hardly half the length of the abdomen. Black ; the pedicel of 

 antennae, at apex, the trochanters more or less, a small spot at base of all tibiae, 

 sometimes wanting on hind pair, tibial spurs and joints i to 4 of all tarsi, except 

 sometimes the last, testaceous. Head and abdomen, except first segment, shining, 

 impunctate ; thorax and first segment of abdomen shagreened or closely punctate. The 

 head is quadrate, wider than the thorax; the antennae are i6-jointed, longer than the 

 body, with flagellar joints i and 2 about equal, very little longer than the following, 

 the following subequal. The thorax is considerably narrower than the head, somewhat
