Face finely shagreened, the front rather strongly evenly con- 

 vex and with a fine complete median carina. Basal lateral area 

 of face sculptured as in Kana illaborata. Vertex (Plate 4, fig. 

 31, a) about one and a half times as long as wide between eyes, 

 the curve of lateral margin of head even from the eyes to the 

 subangulate apex. Ocellus on the rounded curved anterior 

 border passing to the front, about four times its diameter from 

 eye ; the sharp fine carina bordering anterior margin of vertex 

 becomes weak near ocellus, passes above it and is lost in the 

 callose lateral margin of vertex adjoining eye; there is a distinct 

 subocellar carina just below the ocellus which joins and is con- 

 tinuous with the supraocellar carina some distance beyond ocel- 

 lus; the condition is, therefore, comparable with that in Pytha- 

 mus. Surface of vertex slightly depressed, gently convex, basal 

 two-thirds smooth, apical third sparsely weakly longitudinally 

 wrinkled, the raised callose lateral margins next to eyes rugose. 

 Pronotum two-thirds length of vertex, the anterolateral margins 

 into width somewhat more than three times; basal two-thirds 

 subobsoletely transversely wrinkled and sparsely punctate. 

 Scutellum minutely rugose except the shagreened basal angles. 

 Apical cells in tegmina distinctly larger than in N. placida.

 This very abundant species is remarkably uniform in characters 

 throughout the lowlands. At Baguio, Benguet, Luzon, in the 

 high mountains, it differs by having the claval commissure 

 broadly black and the orange at apex of radical and medial 

 areas extending more or less toward the costa between the oblique 

 fuscous stripes. This form is designated var. montana. 



Genus PSEUDONIRVANA novum 



Type, Pseudonirvana sandakanensis sp. nov. 



Characters as given in the synopsis of genera. This genus 

 includes a number of species formerly referred to Nirvana, as 

 remarked under that genus. It appears to be richer in species 

 than any other genus of the family and to be distributed through- 

 out the Indo-Malayan countries. 



Synopsis of species. 

 a 1 . Ocelli very large and prominent; second and third apical cells subequal 

 in length and parallel sided, their basal cross veins in line or nearly 

 so; tegmina largely reddish yellow, with three long oblique stripes
