Funkhouser gives the following technical description: 



Small robust species, with low pronotum and prominent markings; varies 

 greatlj' in color and somewhat in size; females larger and lighter than males, 

 but with constant markings; transverse pronotal band prominent, pale bor- 

 dered with deep brown; dorsal compression deep and translucent; posterior 

 process short, blunt, not reaching tips of tegmina; tegmina hyaline, with bases 

 and tips slightly brown. 



Head small, subtriangular, pale yellow punctured with brown; base feebly 

 sinuate; inferior margin of face sinuate, c^'peus extending slightly below line; 

 eyes large, gray-brown; ocelli small, yellowish, somewhat nearer to each other 

 than to the eyes; clypeus hairy. 



Pronotum closely and roughly punctate; median compressed spot round, 

 transparent; dorsal crest low, arising above humeral angles and gradually ex- 

 tending with only a faint sinus before posterior process; posterior process short, 

 blunt, tectiform, reaching to bases of apical cells of tegmina. 



Tegmina hyaline, veins prominent, bases and apices smoky hyaline. Legs 

 and undersurface of body uniform flavous. 



Length, 5.5-6.5 mm.; width, 2.4-2.6 mm. 



Internal male genitalia. Styles rather long and slender, curved 

 strongly laterad apically, and bearing several spiny tubercles on the 

 lateral margins just cephalad of the terminal tooth; connective tri- 

 angular; cedagus, viewed laterally, large, U-shaped, anterior arm 

 slightly chitinized and with a large prominence about half way on 

 its cephalic aspect, posterior arm heavily chitinized, apex with file- 

 like teeth on the side opposite the functional orifice. 



Distribution. Reported by Van Duzee from Ontario, Maine, New 

 Hampshire, Massachusetts, New York, New Jersey, Pennsylvania, 

 District of Columbia, North Carolina, Georgia, Florida, Illinois, 

 Kansas, Missouri, Arkansas, Texas, New Mexico and Colorado. 

 There are specimens in the Snow collection from Douglas, Riley, and 

 Pottawatomie counties, Kansas. 



Hosts. Funkhouser gives white, chestnut, red and scarlet oak 

 as hosts.

In this subgenus the pronotum is highest at the anterior end. 

 It is represented in Kansas by a single species.
