ORIENTAL PLANT BUGS—HSIAO 383 
of medium length, anterior coxae long, anterior femora distinctly in- 
erassate, posterior femora slightly thickened at apical third, tibiae 
destitute of spinules, slightly more slender at apex, first tarsal seg- 
ment not longer than second, claws broadly curvate, arolia and 
pseudarolia absent. 
This genus is referred to the subfamily Cylapinae and probably 
related to Fulviws Stal, but it is distinguished from this and other 
genera by the produced frons, compressed clypeus, long anterior coxae, 
and incrassate anterior femora and belongs to a new tribe, which may 
be known as Rhinophrini. 
Genotype.—Rhinophrus borneensis, new species.
