Another Allied Species. 

 Another form, having mucli the general appearance of G. arcuata, 

 but with a more elevated thorax, vs^as taken by me abundantly, in all 

 stages of development, on the leaves of the chestnut, Castanea Ameri- 

 cana, at Palenville, N. Y., in August of 1884. Mr. Uhler having seen 

 examples of it, has given it the manuscript name of Gorythuca poly=- 

 grapha, while entertaining some doubt of its specific distinctness, from 

 " not yet having had all the links to attach it to the nearly related 

 species." In the vicinity of Baltimore it occurs on oaks. 



Injuries of Corythuca. 

 These harmless-looking insects which Dr. Fitch has compared to 

 " a flake of white froth," are caj^able of severe injury to the vegetation 

 that they infest. They live on the sap of different plants and trees. 

 According to Glover, one species closely related to G. arcuata, has 

 been found on the quince trees in Mississippi and Florida, where the 

 bushes were entirely covered with them, in all the stages of larvse, 

 pupae, and perfect insects. Some trees were greatly injured if not 

 entirely destroyed by them. They are said to be able to sting severely 

 when handled {Report Gommis. Agriculture for 1875, p. 126, fig. 36).

A Stinging Plant-Bug. 

 A correspondent from Natchez, Miss., has sent the following 

 communication, narrating an occasional demonstration of a species of 

 plant-bug, which has an extensive distribution throughout the United
