mentioned lateral lines. On the mesopleurse is a large black mark under the wings, 

 with a large yellow space in its centre. There is a small black mark at the apex of 

 the mesosternum ; the sutures joining the meso- with the pro- and metathorax are 

 broadly black. Metanotum black, except two square marks at the base touching the 

 suture, where they are prolonged a little laterally, and a longish mark on either side of 

 the lower median area which bounds them. A large and somewhat roundish mark, 

 bounded with black, on the metapleurse. The upper median area smooth, shining, 

 impunctate, united to the lower median area, the sides of which are distinct. Petiole 

 hollow in the centre, the sides keeled ; the keels continued to the middle of the post- 

 petiole, which is coarsely punctured ; black, except a large yellow mark on either side 

 at the apex. Abdomen coarsely and longitudinally punctured ; the second segment 

 almost striated, its basal three fourths black ; the apex reddish, yellowish at the sides ; 

 the basal half of the third segment black, the rest of which and the remaining segments 

 reddish ; the segments are a little contracted at the base ; the apex acute, pilose ; the 

 sheath of the ovipositor black. The four anterior legs are entirely yellow on the under- 

 side ; the tarsi inclining to fulvous ; the tibiae black above ; the femora also black, and 

 with a longish clear yellow line in the centre of the black part. The posterior femora 

 are broadly black above, yellow like the anterior pairs in the centre, and black also at 

 the apical half on the underside ; the apical half of the tibiae black on the outer side ; 

 for the rest, as also the hind tarsi, fulvous, inclining to yellowish. Coxae marked 

 (slightly on the front pairs) with black on the outer side. The trochanters black at the 

 base ; the hind pair also at the apex. Areolet 4-angled, triangular above. 



The male has the antennae without the white ring found in the female, and the black 

 on the legs is more irregularly distributed ; the abdominal segments are black, reddish 

 yellow at the apex, the two apical ones entirely reddish.

Antennae nearly as long as the body. Head slightly punctured ; palpi, mandibles, 

 clypeus, face, and orbits broadly (but the yellow is not continuous, being interrupted a 

 little near the ocelli and behind) yellow. Thorax slightly punctured. Prosternum, a 

 line on the pronotum, the tegulae, the tubercle below them, two marks in the centre of 

 the mesonotum, scutellum, postscutellum, sternum, the greater part of the mesopleura 

 (all below the hollow, except where it projects a little at the head of the latter), a mark 

 under the hind wings, a large mark on the metapleura, a small mark at the side near 

 the base of the metanotum (curving round the spiracle), and a band down the centre 

 [this is continued to the apex, and laterally from the middle], yellow. Scutellum large, 

 flat, broad, with some shallow punctures ; at the apex is a transverse furrow, behind
