23.4 Baker: Malayan Jassoidea 393 



vertex, the anterolateral margins scarcely longer than poste- 

 rolateral and into width about five times; the surface smooth 

 and shining, the basal area with subobsolete transverse wrinkles 

 and a few widely separated punctures. Scutellum with median 

 basal area subobsoletely transversely wrinkled and apical area 

 subobsoletely rugose. Venation as shown in Plate 4, fig. 38, 

 b; the first oblique cross vein may be indistinguishable; extreme 

 apex of tegmina shallowly emarginate, though this will probably 

 prove to be less well marked in the male. 



Borneo, Sandakan (Baker). Palawan, Puerto Princesa 

 (Baker) . The Palawan specimens are specifically identical with 

 those from Borneo. 



Pseudonirvana longitudinalis Distant. Plate 4, fig. 39. 



Distant, Fauna Brit. India, Rhynch. 4 (1908) (Nirvana). 



This species is described from Tenasserim. Later, in the same 

 work, 33 it is recorded from Burma. Through recent collections, 

 we can extend its known range through Penang and Singapore 

 to Sandakan and also to Hongkong. 



The depth of coloring varies, but the markings are the same 

 in all specimens. The face shows a strong -similarity to that 

 of P. singaporensis. Structures near the ocellus are peculiar; 

 the oblique wrinkles of basal lateral portions of face are few and 

 very strong, carinalike ; from among them a strong carina passes 

 toward upper margin of eyes and closely subtends the ocellus 

 below; this carina is parallel to the supra-antennal carina, leav- 

 ing between them a smooth narrow channel; border carina of 

 vertex becoming subobsolete a short distance before ocellus, 

 sending delicate branches above and below it; the ocellus lies 

 in the line of the bordering carina and about its own diameter 

 from eye. Length of vertex (Plate 4, fig. 39, a) about one and 

 a half times interocular width; the anterior black spot may be 

 emarginate apically; surface subdepressed apically, elsewhere 

 gently convex, smooth medially on basal area, the remaining 

 surface thickly longitudinally or obliquely wrinkled. Length of 

 pronotum about two-thirds the length of vertex, anterolateral 

 margins distinctly longer than posterolateral, and into width* 

 about three and a half times; surface sculptured as in other 

 members of this group. Venation (Plate 4, fig. 39, b) peculiar 

 m the narrow and somewhat curved second apical cell and the 

 very large third apical cell.
