There are three rather distinct seasons for egg-laying — one about the 

 middle of June, one the last of July, and one in September. The eggs 

 are laid during the summer at the base of bud scales of the preceding 

 year, and in the fall in the buds. They are laid in clusters of from three 

 to six eggs, in a finger-like mass. About one month is required for the 

 processes of mating, oviposition, incubation, and hatching of the summer 

 eggs, and about twenty days for the development of the nymphs. The 

 greatest number of adults therefore appear early in June from the eggs 

 that winter over, and the middle of July, the last of August, and the 

 middle of October from the summer eggs. The periods, however, are 

 more or less irregular and all nymphs do not mature at an equal rate, so 

 that the immature forms of all stages may be found during the greater 

 part of the summer.

 rounded, not prominent, extending beyond eyes to a distance equal to width of eyes; faint, 

 percurrent, median carina; posterior process strong, acute, sharp at tip, extending as far 

 as terminal cells of tegmina; color of pronotum yellowish brown with markings of dark brown 

 and white, irregular brown spots on front of pronotum over eyes; diagonal light band extending 

 on each side from apex of metopidium to lateral margin, this band having a dark brown 

 posterior border; broad transverse light band just before posterior apex, this band bordered 

 before and behind with dark brown. 



Tegmina subhyaline, extending beyond apex of posterior process of pronotum; basal 

 areas fuscous, punctate; costal cells punctate for almost the entire length; fuscous cloud 

 in middle of each tegmen continuing dark pattern of pronotum above.

 behind middle as seen from lateral outline; color deep brown, almost black; fasciae narrow, 

 but conspicuous because of dark color around them. 



Tegmina with veins very heavy and black. I'ndersurface of abdomen dark broWn, seg-
