Very common. Abundant on various species of oak and often 

 taken on other hosts in the neighborhood of oaks, where, as the 

 insects are strong fliers, their appearance may be accidental. 



The species is distinct and well marked, the females being 

 uniform green with the pronotum closely punctate, and the males 

 brown with a light golden stripe down the median dorsal line, this 

 stripe being broken near the posterior end of the pronotum so 

 that the whole marking appears as a long dash followed by a dot. 

 The insect is considerably smaller than the preceding species and 

 the crest is highest above the humeral angles. In the females the 

 tegmina are entirely hyaline ; in the males they are smoky hyaline 

 with brown at the apices. 



The eggs and nymphs have been found only on oaks — chiefly 

 white oak — which doubtless accounts for the specific name, and the 

 life history is apparently passed on the one host. 



Hosts : White oak, chestnut oak, red oak.

Not common. The smallest species of the genus. Both sexes 

 are green but the species may be recognized by the smooth polished 

 surface of the pronotum, the punctures being very fine or obsolete. 



It occurs on most species of oaks but its life history is not 

 known. 



Hosts : White oak, red oak, scarlet oak.

Three records from the State. May be more common than the 

 records would indicate as the type locality is New York. 



This species stands between the true Cyrtolobus and the true 

 Atymna forms and we believe, and have suggested to Mr. Wood- 

 ruff, that his assignment of the species to Atymna was questionable 

 since the crest is highest over the posterior end of the humeral 

 sinus. The color is greenish with an anterior transverse vitta,
