are rather strongly and abruptly convexly raised above the 

 lateral sutures, the disk rather strongly convex from side to 

 side and divided by the strong, sharp, complete median carina 

 which does not extend on to clypeus. Supraocular carina as in 

 Pythamus, but the subocellar carina passes down and to the 

 side, closer to it, making the ocellar area narrowly long trian- 

 gular (Plate 2, fig. 16, b) ; the frontal suture is very strong and 

 deeply cut above the scrobe, curves around the extremity of the 

 subocellar carina, and extends as a delicate carina medially 

 through the ocellar area toward apex of front, being the only 

 carina within this area, except one above this still more delicate 

 and immediately subtending ocellus; surface of ocellar area 

 coarsely shagreened like the front. Supra-antennal area finely 

 transversely wrinkled throughout, strongly depressed along eye 

 margin, this with the effect of the deep-cut frontal suture giving 

 it the appearance of being produced to a point at the upper border 

 of scrobe. Ocellus in the usual position for Pythamus, about 

 two and a half times its diameter from eye. Vertex a little 

 longer than wide, narrowed to an acute apex, the upper lateral 

 portions of face broadly visible in dorsal view (Plate 2, fig. 16, 

 a) ; median carina sharp and strong, of equal height throughout, 

 but not laminately raised, lateral areas gently concave, the 

 surface finely longitudinally obliquely wrinkled except near 

 carina basally. Pronotum shorter than vertex, the anterolateral 

 margin into width four and a half times; surface strongly 

 transversely wrinkled except near anterior border, as in Pytha- 

 mus decoratus. Entire basal area of scutellum thickly finely 

 punctate and coarsely shagreened, the apical area finely rugose. 

 The scutellum, as in all species of the genus, is proportionally 

 larger than in Pythamus, and as in all but one (hello ggii) longer 

 than the pronotum. Entire clavus, base of corium, and borders 

 of veins subobsoletely punctured; two well-defined cross veins 

 in distal half of subcostal area (Plate 2, fig. 16, d) . Hind tibia? 

 even more strongly long spiny than in Pythamus.

 Onukia corporaali sp. nov. Plate 2, fig. 17. 



Pale ochraceous below, intense shining black above; upper 

 half of entire face and propleuras black. Subcostal area of 

 tegmina pale testaceous as far as an oblique black stripe at two- 

 thirds of length ; beyond this a large triangular decolored area 

 which extends mesad across apical portion of radial cell; the 

 cross vein at middle of this area broadly carmine, the red ex-
