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

 veins dividing the third and fourth discoidal areolels. There are 

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

 the Cicadae, with the exception of a few <if the smallest, show the 

 rudiments of these veins between the above-mentioned areolels where 

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

 of the invisible cross-veins.
