Very common. Usually abundant on quince wherever this fruit 

 is grown in the eastern states. 



Near the preceding species in size and shape but at once recog- 

 nized by the very characteristic markings. The entire pronotum 

 is strikingly decorated with areas of chestnut-red, pale whitish 

 yellow, and deep brown. The crest is erect, broad, flattened, and 

 dark in color. The legs are very hairy. 



The species apparently spends its entire life on one host but the 

 life history is not completely known. 



Hosts: Quince, hawthorn, crab-apple, rose (cultivated), pear.

Not common. Has been collected in New York State on white 

 oak but Mr. Woodruff reports that he has taken it almost invariably 

 on black oak (Q. velutina). 



A fine large species, dark gray mottled with brown, and distin- 

 guished by the very long flattened crest which is almost as high as 

 the insect is long and is usually swollen at the tip. The humeral 

 angles are prominent and triangular; the tegmina are hyaline, 

 tipped with brown. 



Hosts : Black oak, white oak.

Heliria Stal. 



Heliria is a genus of rather doubtful standing, the characters, 

 like those of Glossonotus, depending on the shape of the pronotal 

 crest, which is supposedly step-shaped. No species of this genus 

 have been found in the State but the two following should occur :
