THE BROWN COTTON-BUG. 



(Euschistus servus Say.) 



DISTRIBUTION. 



Dr. p. K. Uhler states" that Euschistus servus (PI. I, fig. 2; text 

 figs. 12, 13) inhabits Texas, New Mexico, Cahfornia, ''Dakota," 

 Ilhnois, Maryland, and the Southern States generally. Mr. E. P. 

 Van Duzee, who possesses the most extensive collection of the Penta- 

 toniidse of America, states ^ that he has not seen types of this species 

 from north of New Jersey and Ohio or west of Kansas, Texas, and 

 eastern New Mexico. In Texas the species is of common occurrence 

 throughout the eastern half 

 of the State, being much 

 more common in the north- 

 ern portion of this section 

 than in the southern por- 

 tion. Toward the western 

 and northwestern portions 

 of the State the species grad- 

 ually diminishes in num- 

 bers, possibly owing partly to 

 decrease in cotton acreage. 

 In Louisiana the brown cot- 

 ton-bug is found throughout 

 the State, though appar- 

 ently, as in Texas, is more 

 common in the central and 

 northern than in the south- 

 ern portion. 



POOD PLANTS.

been taken on several other Enlarged 6 diameters. (Original.) 



plants in addition to cotton, but specific records of actual feeding have 

 not been made except in the case of specimens found feeding on the fruit 

 of the orange in Florida,'^ and a specimen which the writer has observed 

 feeding on green fruit and twigs of peach in confinement. The agents 

 of the Bureau of Entomology who were connected with the cotton" 

 boll weevil investigations have collected this species in Texas and 

 Louisiana on the following plants: Hehanthus (three locahties), 

 corn (two locahties), Heterotheca sulaxillaris (two locahties), Rud-
