HEMIPTERA HETEROPTERA. 535 
Black, shining, convex, regularly elliptical. Head slightly rugulose 
on each side. Eyes piceous. Antenne tawny. Thorax and scutellum 
very finely punctured, the former smooth in front. Legs stout; tibia 
thickly spinose; tarsi pale yellow. Fore wings rather more finely punctured 
than the thorax; membrane colourless. Length of the body 2 lines. 
It much resembles ZZ. pallidicornis, but is rather smaller and the 
antenne are of one colour. The colourless membrane will distinguish it 
from AY. maurus, and its broader form from 4?. pygmeus and from 
4!, apicalis.
