Parshley (1921 b, p. 3) has recently questioned the validity 

 of this species. I have examined too few specimens to have 

 reached any definite conclusions on this point, but I may note 

 that I have seen two apparently distinct North American 

 forms in this genus, quite different in habitus but very difficult 

 to distinguish on a structural basis. I hope to publish further 

 on this genus in the near future. 



One specimen of the brachypterous form which has com- 

 monly been referred to this species, even by Uhler himself, 

 was taken at Amidon, August 24, from goldenrod in the bot- 

 tom of a gully in the "breaks" of the Bad Lands. This form 

 cannot possibly be referred to C. humilis, or even to the genus 

 Coriomerus, for the structure of the metathoracic orifices 

 excludes it from the subfamily Pseudophloeinae : I have seen 

 only brachypterous individuals, and so can give no informa- 

 tion regarding the venation of the membrane and the alae. 

 This insect possesses some characters in common with Sco- 

 lopocerus, but differs from that genus in the position of the 

 spiracles. In all probability it represents a genus still unde- 

 scribed, as has been suggested to me by Mr. Barber. 



Harmostes reflexulus (Say). — One specimen, from the 

 Chalky Buttes near Amidon, August 22, is in the collection. 

 Uhler (1878, p. 505) lists it from the Mouse River. 



Coriziis lateralis (Say). — Uhler (1878, p. 505) records this 

 form from the Turtle Mountains. Neither this nor the next 

 species was taken by Hubbell. 



Corizns crassicoriiis (Linne). — Reported from Pembina by 



Uhler (1878, p. 505). under the name C. punctiventris Dallas. 



*L,eptocoris trivHtatus (Say). — Collected at Devils Lake, 



May 7, 1921 (N. A. Wood), and at Grand Forks (H. A. 



Shaw).
