Rare. Occasionally taken on goldenrod, on which host it is very 

 abundant in other parts of the State. 



The species may be recognized b}^ the slight dorsal depression and the 

 general rounded shape of the pronotum, characters which separate it from 

 Entylia boctriana, the only other species with which it is likely to be con- 

 fused. Like E. bactriana this species shows variation in color and in 

 pronotal development. 



H. H. Knight has taken this species in large numbers at Batavia, New 

 York, from goldenrod. Nymphs and adults furnished by Mr. Knight have 

 been successfully transferred to the same host plant in Ithaca, where they 

 throve well and yielded complete life-history data. No eggs were laid in 

 the late fall, and it is presumed that this species, like the one preceding, 

 winters over in the adult stage. This presumption is l^orne out by the 

 fact that Harold Morrison has collected adults at Freeville on May 29 

 (in 1913), a date that would be too early to admit of development from 

 the egg. 



The variety m'gridorsutn of Goding (Coding, 1894) is found with the 

 typical forms of the species and is not here considered as distinct. 



Technical description. — Varies greatly in color and somewhat in shape, particularly in 

 form of dorsal sinuation; color varies from gray to black; dorsum convex, tectiform, faintly 

 ribbed, dorsal sinus shallow; pronotum irregularly ridged, deeply punctate; tegmina largely 

 covered by pronotum, basal half of each costal area strongly punctate. 



Head slightly projecting, strongly punctate with black; base nearly straight; inferinr 

 margin rounded; eyes not prominent; ocelli prominent, usually reddisli; clypeus roundeil. 

 very wide at tip. 



Pronotum deeply, densely, and coarsely punctate, lateral areas marked with high, distinct, 

 irregular, longitudinal ridges; dorsal margin sinuate just behind humeral angles, sinuatinn
