Head shining, aciculate, the cheeks, clypeus, and labrum covered with a silvery 

 pubescence ; the ocellar region raised ; the anterior ocellus in a pit ; the space between 

 and above the antennae distinctly projecting; the clypeus at the apex slightly arcuate ; 

 the labrum rounded, the sides oblique ; the eyes at the top arcuate ; the ocelli in a 

 curve, the hinder pair separated from each other by a less distance than they are from 

 the eyes; a furrow runs down from them; the occiput convex. Thorax bearing 

 widely separated shallow punctures, the median segment alutaceous; the prothorax 

 arcuate in front, bulging out laterally at the base ; scutellum raised, not much narrowed 

 towards the apex. The median segment with a small triangular depression at the base, 

 from which runs a wide channel ; broad at the base, narrowed at the apex. Abdomeii 

 not much longer than the thorax, sessile, curved. Antennas stout, a little thickened 

 towards the apex ; the joints closely united. Radial cellule elongate, narrow;, 

 lanceolate ; the second cubital cellule at the top distinctly longer than, at the bottom 

 nearly as long as, the third cellule ; the third cellule at the bottom more than twice as 

 long as at the top ; the first transverse cubital nervure curved ; the first recurrent 

 nervure received in the apical fourth of the cellule — at a little less distance from the 

 apex that the second is received from the base of the cellule. Legs elongate, especially 

 the hind tarsi. Black ; the clypeus and face, the inner orbits broadly, the outer orbits 

 narrowly, the edge of the pronotum, the tubercles, a spot on the scutellum, the meta- 

 notum, a mark on the median segment in front of the coxa?, an incised elongate spot 

 on the side of the first segment, a transverse one at the apex, a line on the apices of 

 the other segments, incised at the sides in front, the coxae in front and a line on the 

 hinder pair at the side, and the scape beneath, yellow. 



The male is similarly coloured to the female, except that the labrum is yellow, the 

 first abdominal segment has only a somewhat oblong mark at the sides, the lines on 

 the three following segments are broken up into three, and the following two segments 

 have an entire mark in the centre; it has the apical segment wide, broadly incised.
