Very abundant. Found chiefly on trees, particularly various 

 species of oaks. Less common on grasses, in which respect it 

 differs from the preceding species. One of the most interesting 

 of the records from Connecticut is the taking of the insect on 

 white pine at Portland by F. W. Haasis, June i, 191 5. Very few 

 membracids have ever been reported from any of the conifers. 



The life history is not known but apparently its habits are quite 

 different from those of ^. inermis. 



Hosts : White oak, red oak, black oak, white pine, daisy.

Acutalis Fairmaire. 

 This genus is represented in Connecticut by at least two species. 

 The genus is characterized by the small size of the insects, the 

 dark and shining pronotum, and the five apical cells of the tegmina 

 set oft" by distinct veins.

Not common in the New England States but occasionally 

 reported from eastern New York and from Massachusetts. In 

 the central and southern states, where it is abundant, it is taken 

 on both trees and annuals but its life history has not been worked 

 out. In Mississippi it is common on pecan; in Kentucky its 

 favorite hosts seem to be wormwood and soapwort. 



The insect is small and elongate (length 4.5 mm. ; max. width 

 2 mm.), pronotum and tegmina very black but sometimes showing 

 a hyaline apex to the tegmen and a white lateral margin on the 

 pronotum.
