niSTKIBUTION. 



The original description of Pentatoma ligata^ bj? Thomas Sa}^," Avas 

 based on a specimen from JNIissouri. Uhler ^ notes that the species 

 occurs in Missouri and Texas, doubting the statement of Fitch ^ that 

 it occurs in New York. Herrich-Schaeffer '' described what is now 

 generally cou*sidered Say's species under the name of Chnex rufo- 

 cinvtas^ from specimens from JMexico, and Kouchakevitch ^ described 

 specimens from '' Russian America," under the name of Giniex rufo- 

 i/ungi/tafi/.s^ Avhich Van Duzee ^ places as a synonym of P. ligata. 

 Smith ^ records /*. Jlgata Say as occurring, though " rare," at Cald-

 Vtgata ranges fronr Mexico northward through the Kocky Mountains 

 to Vancouver Island, and apparently still farther north to Alaska."
