record of this species from so high a latitude in North Ameri- 

 ca. It is in all likelihood an adventitious visitor, very probably 

 imported in nursery stock from Europe, either as an egg or 

 a nymph, or else possibly brought from Florida. The specimen 

 is quite typical, and varies no more than in the usual degree 

 from the more clearly marked individuals that I have seen. It 

 lacks the 3 or 5 white points at the base of the scutellum along 

 the edge of the pronotum, although there are indistinct smooth 

 concolorous spots where they are usually to be found. 



It might seem that there is no reason why this form should 

 not be able to establish itself here, as it is quite at home in 

 Germany and Russia, where certainly the winters are no 

 warmer than in the United States. We therefore have in the 

 North Atlantic States three species of Nezara to look out for, 

 namely Nezara hilaris Say, pennsylvanica De G. and possibly 

 viridula Linne. They may be separated as follows: 



1 (2). Osteolar canal short, truncated, scarcely extending in a ruga. 

 (S. K. Nezara A. & S.) 



N. viridula Linne. 



2 (i). Osteolar canal extending in a long narrowing ruga. 



(S. g. Acrosternum Lieb.) 



3 (4). Anterior sides of pronotum rounded; rostrum scarcely reach- 

 ing the middle coxae; species broad oral. 



N. (A.) pennsylvanica DeGeer. 



4 (3). Anterior sides of pronotum straight; rostrum reaching hind 

 coxae ; species elongate oval. 



N. (A.) hilaris Say. 



In addition to these characters, N. viridula has a black dot 

 at each basal angle of the scutellum, and the 2d and 3d an- 

 tennae joints subequal, while in hilaris the dot is absent and 

 the second joint is slightly longer than the 3d. N. pennsylvani- 

 ca in addition to the characters given has broad head slightly 

 blunt and incised in the middle, characters absent in the other 

 two. Viridnla is a duller inject ; the other two more polished. 



N. viridula is recorded as feeding on orange, Celtis, mul- 

 berry, rice, sugar-cane, cotton, maize, potato and Gynandropsis 

 pcntaphyllum; hilaris also feeds on orange, cotton, bass-wood, 

 trumpet-creeper, cowpeas and tomatoes, all these according to
