cephalad) , the latter continued across pronotum and on to scutel- 

 lum. Tegmina hyaline, with the usual three fuscous stripes 

 in subcostal area, the space between the second and third of 

 these and the apical veins more or less yellow. Length, female, 

 6 millimeters; male, 5. 



Basal lateral areas of face about as in P. longitudinalis, with 

 the remarkable difference that the carinate wrinkle, which passes 

 obliquely upward to subtend the ocellus in that species, here 

 joins the bordering carina of vertex, the ocellus lying above the 

 bordering carina, the latter beyond this point and toward the 

 eye being lost in many fine longitudinal wrinkles; the ocellus 

 is small and more than its own diameter distant from the eye. 

 The length of vertex (Plate 4, fig. 35, a) is one and a half 

 times the interocular width; median carina on basal third fine 

 and set in an incisure ; surface broadly slightly depressed, largely 

 smooth, indistinctly wrinkled or rugose near apical margin and 

 in basal angles. Median basal area of scutellum smooth. Vena- 

 tion (Plate 4, fig. 35, b) peculiar in the distally narrowed sec- 

 ond apical cell and in the strongly outcurved third apical vein. 

 Borneo, Sandakan (Baker). Straits Settlements, Penang 

 Island and Singapore (Baker) . In coloration of head and pro- 

 notum this common Malayan species resembles P. sanguineo- 

 lineata, and in venation, P. penangensis, but is distinct other- 

 wise. As usual, the head of the male is a little shorter and 

 more pointed. Three males from Penang (normal males are 

 common there) have the whole upper surface strongly suffused 

 with golden yellow, and this form is designated var. auricolor. 

 Pseudonirvana sandakanensis sp. nov. Plate 4, fig. 36. 



Very pale ochraceous; a small apical cloud on vertex and 

 anterior half of median carina reddish or blackish. Tegmina 

 subhyaline, an irregular faintly orange cloudy band extending 

 transversely from apex of clavus to costa ; three fuscous stripes 

 m subcostal area in usual position, the first faintest; a large 

 round black spot lying half in second apical cell and half in 

 third. Length of female, 4.25 millimeters. 



Differs from P. davaoensis in structure as follows; Median 

 frontal carina a little raised basally. Sculpture of basal lateral 

 areas of face similar to that of Kana illaborata instead of Pytha- 

 mus. Ocellus situated above the carina which actually borders 

 anterior margin of crown, but a short branch of this carina 

 passes to inner border of ocellus. Length of vertex (Plate 4, 

 fig. 36, a) about one and a half times interocular width, the
