All the other characters as in the " Europaischen Hemiptera," p. 
245, and " Entomologist's Monthly Magazine," Vol ii.,p. 248. 
As the insect described below appears to be the developed form 
of this curious genus, the characters originally laid down by Dr. 
Eieber in the " Europaischen Hemiptera," and by us in the " Entomo- 
logists' Monthly Magazine," are not any longer strictly applicable. 
We, therefore, have to add the following, in order to make the charac- 
ters complete. Besides this, it seems probable that the genus will 
require to be removed from the Bicelluli and placed in the Division 
Unicelluli, as we can only observe a single cell in the membrane. Eor 
the present, however, it is as well to leave it where it now is until a 
series of examples has been examined, in order to ascertain whether 
there is any variation in this respect.
