Note. — C. Aquila and C. Accipiter have two additional cross- 

 veins dividing the third and fourth discoidal areolets. There are 

 indications of this disposition in other large species, and nearly all 

 the Cicadas, with the exception of a few of the smallest, show the 

 rudiments of these veins between the above-mentioned areolets where 

 the longitudinal vein has a knot which is the point of intersection 

 of the invisible cross-veins.
