226 Mr. P. Cameron on Twelve JVew Genera and 



5-augled, narrowed above. Legs longish ; the tarsi long, the hinder 

 almost twice the length of the tibise ; the apices of the joints spined. 

 The post-petiole becomes gradually wider from the base to the 

 apex and is not clearly separated ; the gastrocceli large and deep ; 

 the head is not largely developed behind the eyes, and becomes 

 oliliquely wider below before the middle ; the eyes are large and 

 are sharply margined on the inner-side. 



A genus easily known by tlie long antennae dilated 

 beyond the middle, by the curved mandibles with long 

 apical tooth, by the long spined tarsi and by the abdomen 

 having eight segments.

Black ; the face, clypeus, the inner orbits, the outer — narrowly 

 above, entirely below — the lower part of the prothorax, the edge of 

 the pronotum, two lines on the basal two-thirds of the mesonotum, 

 the scutellum, except a narrow line down the middle, a squarish 

 mark on either side of the base of the metanotum, its lateral areae 

 entirely, the lower half of the mesopleuraj, a mark under the hinder- 

 wings, the metapleuraj from shortly behind the middle, where they 

 are obli({uely rounded, a small mark at the spiracles, the sides and 

 apex of the post-petiole, the apices of the 2nd and 3rd segments 

 broadly laterally, more narrowly in the centre, a line on the apex 

 of the 4th, interrupted in the middle, a small round spot on either 

 side of the middle of the 5th, the 6th on the apical half of the middle, 

 the whole of the 7th, and the 2nd, 3rd and 4th ventral segments for 

 the greater part, pale yellow. Legs fulvous ; the four front coxae 

 and trochanters and the hinder coxse, pale yellow ; the apex of the 

 latter on the outer-side, the apex of the hinder femora, of the hinder 

 tibia3 and the base of the metatarsus, black. Wings hyaline, the 

 stigma pale, the nervures black. 9 •

Antennas black, as long as the body, the scape lieneath and the 

 9th to IGth joints white beneatb. Face and clypeus closely punctured 

 all over and sparsely covered with pale pubescence ; the vertex more 

 sparsely punctured, more closely and distinctly at the ocelli than 

 below ; the black band on the vertex and front is contracted on the 

 top of the latter. Mesonotum closely punctured ; the scutellum 

 much more sparsely punctured ; the post-scutellum smooth. Median 

 segment closely, rugosely punctured ; the areola is shagreened and 

 is furrowed round the sides and base ; the posterior median area is
