ORIENTAL PLANT BUGS—HSIAO 389 
dark brown; membrane semitransparent, veins concolorous with 
cuneus. Venter brown. Legs yellowish brown, length of posterior 
femora 1.05 mm., length of posterior tibiae 1.3mm. Genitalia similar 
to those of 7. sanguinalis Kirkaldy, left clasper leaflike, with apex 
concealed by the apical margin of the ninth ventral segment. 
This species is unique in the genus. It can be readily distinguished 
from the other species by its small size and the absence of reddish 
color.
