Face with a double row of foveae, commencing at the end of the black central line, 

 6 pairs in ail. Clypeus large, a row of foveae along its top; the labrum not much shorter 

 than it. Malar space as long as the labrum. Metanotal areae roundly narrowed on the inner,

Black, the face, clypeus, labrum, a line on the upper inner orbits, extending from the 

 face to the ocelli, the outer orbits, a broad curved mark, slightly narrowed in front and not 

 reaching quite to the apex, a spot, slightly longer than wide, rounded at the base, transverse 

 at the apex, shortly beyond the middle of the mesonotum, the scutellum, slightly more than 

 the apical half of the médian segment, commencing on the sides of the metanotum at the

 a wider transverse mark on the outer third of the y&, a narrower one, reaching nearer to

 the outer half, its inner half dilated, lemon-yellow. The basai metanotal areae wider than 

 they are long on the outerside, the outer keel oblique, straight, extending beyond the spiracles, 

 the inner longer, curving round from its apex to the base of the metanotum, the inner part 

 longer and more rounded than the outer; from the outer side of the basai area another runs 

 to the apex; it is twice longer than wide, of equal width, with its apex rounded. Ç.
