LAWSON: KANSAS CICADID^. 351 



Color: Head in brown forms either practically unmarked or with an 

 irregular broad transverse black band with a distinct dash projecting 

 cephalad on each side of the base of the front which itself is basally dark 

 except for the light median portion. Pronotum of brown forms either 

 unmarked or the grooves irregularly marked with black. The mesonotum 

 of the brown forms has two short median and two large lateral black 

 linee. The abdominal terga of the brown forms may be unmarked or 

 darkened basally and laterally. The wings of the brown forms have 

 brownish veins, the basal areoles of the fore wings are clear and the flaps 

 of both wings are grayish with a brownish tinge. Beneath, the body is 

 nearly uniformly brown, the legs" being marked with darker lines. The 

 green forms at hand are uniformly green except for a transverse black 

 band on the head cephalad of the eyes, black spots below the antennae, and 

 the rostrum and tips of tarsi blackish. 



Form: The following are the measurements in millimeters of the 

 specimens at hand: 



Length of body 12.25 to 15.5 



Width of head 3.5 to 4.5 



Expanse of fore wings 33 to 40 



Greatest width of fore wing 5.5 to 7 



Greatest width of operculum 3 



Greatest length of operculum 3.25 



The cells of the median area of the forewing are of about the same 

 size or shorter than the marginal cells. This is most constant in regard 

 to the relative length of cells 1st R-, and 2nd R.-.. 



The opercula are quite small, about as broad as long, widely separated 

 medially, and broadly rounding laterally and posteriorly. 



Genitalia: The supra-anal plate of the male when viewed laterally is 

 seen to be strongly pointed dorsally and to have a distinct caudally-pro- 

 jecting dorsal lobe on the posterior margin, just below which is a smaller 

 rounded lobe. The uncus, viewed laterally, appears like a short, acute, 

 curved process. Viewed caudally it consists of two diverging processes 

 which taper to subacute apices. The last ventral segment of the male is 

 triangular, about one-third wider than long, the lateral margins sinuately 

 tapering to the obtuse apex. The pygofers of the female have the mar- 

 gins sinuate to the base of the large median spine. The last ventral 

 segment of the female is very short and the posterior margin is broadly 

 and triangularly emarginate nearly to the base. The ovipositor is 

 equipped with about ten distinct and well rounded teeth on each side.
