Borneo, West Borneo, Mowong (F. Muir) : British North 

 Borneo, Sandakan (Baker). This conspicuous species is very- 

 abundant in Borneo. 



Onukia kelloggii sp. nov. Plate 2, fig. 19. 



Pale ochraceous, the pronotum a little darker. Front with a 

 black dot on either side below antennae. Vertex with a large 

 irregular black spot on anterior half. Pronotum medially and 

 along hind margin blackish. Tegmina pale yellowish to apical 

 cross veins, brighter basally, the entire subcostal and apical areas 

 decolored and hyaline. A dark spot at base of subgenital seg- 

 ment. Length of female, 7 millimeters. 



Differs from 0. muirii in structure, as follows: Sides of 

 front much more gradually curved from disk to lateral suture. 

 Ocellus distant from eye about four times its diameter. Vertex 

 slightly longer than width between eyes. Pronotum (Plate 2, 

 fig. 19, a) slightly shorter than vertex, the anterolateral margins 

 into width about five and a half times, hind margin nearly trun- 

 cate. Scutellum shorter than pronotum. 



China, Fukien Province, Foochow (C. R. Kellogg). A large 

 conspicuous species. More specimens, representing both sexes, 

 are much desired. This species is apparently closely related to 

 Onukia (Apphia) burmanica Distant. 21 



Genus ONIELLA Matsumura 

 Matsumura, Annot. Zool. Japon. 8 (1912) 46. 



Type, Oniella leucocephala Matsumura (Japan). 



This genus is a weak, reduced edition of Onukia. It is how- 

 ever true here, as all through these allied families, that strong 

 superficial resemblance may be accompanied by striking generic 

 divergence in structural characters. As indicated in the generic 

 synopsis and the accompanying illustration (Plate 2, fig. 20), 

 this genus is well separated from Onukia. 



Matsumura refers here two species from China described by 

 Melichar as Tettig oniella excelsa and T. honesta. 22 They appear 

 to belong to this family ; but since Melichar figures both of them 

 with the head distinctly wider than the pronotum, it may be 

 questioned if they belong in the genus Oniella. 



In the paper above mentioned, Matsumura describes another 

 species, O. niisimae, from Japan.
