23,4 Baker: Malayan Jassoidea 389 



and two-thirds times width between eyes; surface evenly 

 gradually depressed, the basal half of median carina set in a 

 shallow incisure; median basal area smooth with a few punc- 

 tures, the remaining area thickly finely longitudinally wrinkled. 

 Length of pronotum about half length of vertex, anterolateral 

 margin into width about four times. Venation (Plate 4, fig. 33, 

 b) peculiar because of the long narrow parallel-sided second 

 apical cell, and the strongly outcurved third apical vein, in this 

 resembling P. ocellaris. 



Straits Settlements, Penang Island (Baker). 

 Pseudonirvana singaporensis sp. nov. Plate 4, fig. 34. 



Very pale ochraceous throughout, with no black markings. 

 Tegmina hyaline, with the usual three transverse fuscous stripes 

 in subcostal area, but in this case very faint. Length of female, 

 6 millimeters. 



Differs from P. penangensis in structure as follows: Frontal 

 depression reaching nearly to extreme base of face. Ocellus 

 small, twice its diameter from eye, situated in a depression 

 distinctly behind the bordering carina of front and behind the 

 thickened margin, the bordering carina anterior to ocellus being 

 lost in numerous fine wrinkles, and about apex of vertex very 

 weak. Vertex (Plate 4, fig. 34, a) large and broad, length 

 nearly one and a half times the interocular width, the width of 

 the whole head being nearly that of pronotum; anterior half 

 of median carina of vertex obsolete, posterior half finer and 

 set in a shallow incisure ; surface evenly depressed, smooth except 

 narrowly before apical margin where it is indistinctly longi- 

 tudinally wrinkled. Length of pronotum half that of vertex, 

 the anterolateral margins into width about six times. Venation 

 (Plate 4, fig. 34, b) peculiar because of the long trapezoidal 

 second apical cell, and the strongly sinuate outer apical vein. 



Straits Settlements, Singapore (Baker). This cannot be 

 the other sex of P. penangensis due to the widely different 

 structure, although they are somewhat superficially similar in 

 entirely lacking strong color markings. 

 Pseudonirvana malayana sp. nov. Plate 4, fig. 35. 



Very pale ochraceous; face medially ochraceous, margins 

 whitish ; apical submargin of vertex with a blood red transverse 

 line; side margins of vertex and apical half of median line 

 washed with yellowish ; lateral areas of vertex divided medially 

 by a broad longitudinal ivory white band (the two diverging
