Probably rare but found in New York, Massachusetts and New 

 Jersey. A fine large species, the type of the genus. The body 

 color is gray with irregular brown markings. The crest is large 

 and shows the very characteristic "step" on the dorsal margin, the 

 anterior half of the crest being twice as high as the posterior, with 

 the posterior angle very acute. The humeral angles are greatly 

 produced. 



Hosts and life history unknown.

Should be common according to eastern locality records but 

 has not yet been reported from the State. 



A small species, uniform brown in color, crest as high or higher 

 than long, posterior process not reaching apices of the tegmina 

 which are smoky hyaline with brown tips. 



Hosts and life history unknown. 



Telamona Fitch. 



Practically all of the species of this genus have been described 

 from pronotal characters only, and as such characters are decidedly 

 variable and not always dependable, the diagnosis of species is 

 often difficult. The following key is admittedly artificial but it 

 is believed will be sufficient to distinguish the species included, 

 most of which are apparently distinct and rather well known.
