The true E. hifida.^ Say,= £'. albirennis, H.-Scliiitf., is, 

 so far as I am aware, coiitiiied to the United States of 

 America or to the Nearctic Region. It differs from E. cornuta, 

 judging from typical specimens forwarded from that region, 

 by the broader apex of the scutellum. Mr. Uhler {supra) 

 states that E. bifida, Say, and E. cornuta, Burm., are syno- 

 nymic ; but tliis seems to be erroneous, and as he returned 

 specimens oi E. cornuta to the British Museum under both 

 names, he probably did not have true specimens of Say's 

 species before him when he wrote. Tiie two species are 

 certainly closely allied.

Strachia affiicta. Walk. Cat. Ilet. ii. p. 332. n. 67 (1867). 



I am doubtful as to the generic position of this species. It 

 seems to belong to Ilt/parete or some allied genus ; but as I 

 have not been able to examine a representative of Stal's 

 genus and Walker's type is the only specimen of his species,
