FAMILY MEMBRACIDjE. 153 



The following species are among the most interesting, and deserve attention as much, 

 if not more, from their peculiar tbrms and habits, as from their infliction of injury upon 

 the products of the farm*. 



Membracidae. 



Gems EXTTLIA (Germar). ( Plate xiii.) 



Back more or less notched or sinuate : thorax foliaceous. 



Entilia sinuata (Fab.). ( Plate xiii, fig. 11 ) 



Back deeply sinuate-notched, or slightly angulated. Color brown : wings variegated with 

 a patch of grayish white, broad upon the lower margin, and becoming narrow upon 

 the superior. 



Extilia emargixata. (Plate xiii, fig. 13.) 



Back deeply notched or sinuate. Color brown : proportionately shorter than the sinuata. 



Entilia coxcava (Say). ( Plate xiii, fig. 10.) 



Back simply sinuate, more depressed than in either of the preceding species. Color brown : 



wings obscurely banded with gray posteriorly. 



The preceding species differ but little in size : they are about a quarter of an inch in 



length, and inhabit the Canada thistle and other herbs and trees, but are not known to 



injure any of the cultivated plants. 



Gexus SMILIA (Germar). ( Plate iii.) 



Back rounded ; the front sometimes overhanging the head, and higher than the back. 



Smilia auriculata ( Fitch). ( Plate iii, fig. 23.) 



Back rounded, high and arched anteriorly : color green ; front projecting along the 

 median line. 



Smilia guttata. ( Plate iii, figs. 21, 22.) 



Back slightly arched, nearly straight, fuliginous : oblique anterior band narrow and 

 obscure ; posterior is a large greenish spot, extending nearly to the inferior margin 

 of the wing-covers : a still more obscure grayish marking posteriorly. 



• For specimens and names of the following genera and species, I am indebted to our distinguished entomologist, 

 Dr. Asa Fitch, of Washington connty.
