A NEW SPECIES OF BOLTERIA (HETEROPTERA, 

 MIRIDAE). 



By Harry H. Knight, University of Minnesota, St. Paul. 



(Published with the approval of the Director as Paper No. 257 

 of the Journal Series of the Minnesota Agricultural Experi- 

 ment Station.) 



In a previous paper (Bul. Brook. Ent. Soc, xiv, pp. 126-128 

 (1919)) the writer has shown that the unrecognized Bolteria 

 amicta Uhler is in fact the same insect which was later described 

 as Dichrooscytus speciosus rubropallidus Knight (Bul. Brook. 

 Ent. Soc, xiii, p. 115 (1918)), and that Dichrooscytus speciosus 

 Van Duzee stands as a good species in the genus Bolteria. A 

 correction should be made in the writer's previous paper (Bul. 

 Brook. Ent. Soc, xiv, pp. 126-128 (1919)) on the genus, in that 

 " nigropallidus" should in all cases read rubropallidus.
