23.4 Baker: Malayan Jassoidea 3gl 



fig. 24, a) somewhat longer than width between eyes, the lateral 

 margins in front of eyes straight for a short distance; anterior 

 border margined by a sharp carina— the subocellar carina of 

 Pythamus; the ocelli are thus on the upper surface of the flat 

 crown though subtended mesad by a delicate subobsolete sinuous 

 carina which represents the supraocellar carina of Pythamus; 

 ocelli nearly four times as far from each other as from lateral 

 borders of crown and distinctly in front of anterior line of eyes ; 

 just within the anterior margin of crown is a sharp, narrow, 

 concentric depression, giving the anterior margin somewhat the 

 appearance of being reflexed ; median carina sharp and complete, 

 but less strong anteriorly; surface of vertex smooth. Length 

 of vertex a little more than interocular width. Pronotum a fifth 

 shorter than vertex, the anterolateral margins into width a 

 little less than five times ; hind border slightly incurved ; a broad 

 median area very finely thickly transversely aciculate, the 

 remainder of surface smooth. Subgenital plate broadly obtuse- 

 angularly extended at middle. Venation (Plate 3, fig. 25, a) 

 of tegmina peculiar because of the very large and long apical 

 cells of similar length, the second and fourth larger and of 

 subequal breadth ; appendix inconspicuous ; venation of wing as 

 in Plate 3, fig. 25, b. 



Borneo, Sandakan (Baker). Straits Settlements, Singa- 

 pore (Baker) . This appears to be nothing more than a form of 

 the species described by Distant from Tenasserim. It is common 

 in North Borneo. 



Kana picea sp. nov. Plate 3, fig. 26. 



Black and piceous, shining; legs, anterior margin of crown, 

 and abdomen except segmental margins pale ochraceous ; scutel- 

 lum, and clavus except two oblique black spots on inner margin 

 at middle and extreme apex, chestnut brown. Tegmina piceous 

 to apical cross veins except a small chestnut brown spot in 

 cubital area at two-thirds its length, and a large subhyaline 

 triangular area next outer margin apically, the inner point of 

 this triangle reaching into radial cell, from this two oblique 

 piceous stripes extending to apical margin; the margins of the 

 subhyaline area, and the apical cross veins yellowish to reddish. 

 Extremities of hind tibias and of first tarsal joint black. Length, 

 female, 5 millimeters ; male, 4. 



Differs from K. illaborata in structure as follows: Face (Plate 

 3, fig. 26, c) a fourth broader than long; front similarly flattened 

 but entirely without a median carina, whole surface very finely
