mesonotum with a shallow furrow on the basal slope. Areola 

 A -shaped, pointed to the base of the metanotum by a A -shaped 

 furrow ; it bears 3 stout, transverse keels, the basal being less 

 distinct than the others ; from it stout transverse keels run to 

 the outer edge of the metanotum, the lower ones going beyond 

 the spiracles. Areolet square ; the recurrent nervure is dilated 

 backwards at its junction with the cubitus; the transverse 

 median nervure is received shortly beyond the transverse basal. 

 The frontal depression is bordered outwardly by a stout, curved 

 rounded keel.

Black, the basal segments of the abdomen tinged with brown ; 

 the inner orbits opposite the eyes broadly, the face, clypeus, 

 the outer orbits from near the top of the eyes broadly, a broad, 

 oblique mark on the sides of the pronotum in front, base of 

 tegulae, a mark on the scutellar keels, a mark, about the same 

 size, on the sides of the scutellum at the base, 2 large marks 

 on the median segment, broadly dilated inwardly at the base of 

 the metanotum, where they are separated by a narrow black 

 line, proceeding downwards along the outerside of the spiracles 

 and having, immediately below, on the apex of the metapleurae, 

 a smaller mark, longer than wide and dilated above the tuber- 

 cles, a large mark immediately below these, reaching the 

 sternum at the base and having the lower outer edge bi- if not 

 tridentate ; a minute line on the apex of the 1st abdominal 

 segment, 2 large transverse marks near the apex of the 5th, a 

 small, somewhat heart-shaped, mark shortly behind the middle 

 of the 6th in the centre, a much larger mark, twice longer than 

 wide, and slightly narrowed towards the apex, the anterior legs, 

 except the tarsi, in front, a large, somewhat pyriform, mark on 

 the outerside of the middle coxae, a broad stripe down the 

 middle of the hinder coxae, the apex of the middle femora
