Under the o;enus ScoJoposcelis, Fieb. (Palaearctie, Xearctic, and 

 jSTeotropical) Poppius lias included Osiorodias, Dist. (vol. iii, 

 p. 3, tig. 1) and SeseUius, Dist. (vol. iii, p. 7, fig. 6). There must 

 always be a difference in the individual estimation of what 

 constitutes generic characters, but 1 am content to refer to my 

 figures and descriptions. 



The three genera can be thus differentiated. 



A. Anterior femora prominently tliickened and 



spinose beneath. 



a. Head broad, including eyes, about as broad 



as long; pronotum with a prominently 

 raised central longitudinal cariuation or 

 ridge ; scutellum with two profound basal 

 foveiB OsxoRODiAS, Dist. 



b. Head slender, elongate, longer than breadth 



including eyes ; pronotum not prominently 

 centrally raised or ridged ; scutellum 

 without two basal fovese ScoLOPOSCELis.Fieb. 



B. Anterior and posterior femora prominently 



thickened and spinose beneath Sesellius, Dist. 



Poppius has rightly suppressed his S. incicornis (supra) as a 

 synonym of S. paralleius, Motsch. (vol. iii, p. 7). 



Genus HORNIELLA.

Type, H. poUta, Popp. 



Distribution. Ceylon. 



" Body somewhat depressed, strongly shining, above clothed 

 with very short pale hairs, only visible under a strong magnifying 

 glass, the hairs wide apart ; head scarcely longer than its width 

 including the eyes, rather shortly produced in front ; eyes mode- 

 rately large and prominent, a little remote from the front margin of 

 the pronotum ; antennas about as long as head and pronotum
