94 HEMIPTERA-HETEROPTERA. 
This variety is closely allied to the preceding (E. rivosa, Stal); but, besides its much 
larger size, it differs also in the different colour (darker and brighter) of the abdomen 
above, the slightly more recurved apices of the pronotal lateral angles, the different 
colour of the corium, with the base of the costa pitchy, &c. Different as it is, however, 
in colour and size, I can find no structural characters to lead me to consider that it 
is any thing more than a strongly marked variety of E. rixosa; but as I have only seen 
one specimen, and that has the antenne mutilated, which if perfect might give some 
decisive character, I have considered it better to give it provisionally a distinct varietal 
name.
