THE NORTH AMERICAN SPECIES OF MONANTHIA 

 (TINGID^). 



By Carl J. Drake, Ohio State University, Columbus, Ohio. 



The genus Monanthia, established by Lepelletier et Serville in 

 Encyclopedie Methodique, X, p. 653, 1825, is represented in 

 North America by three species. The two tropical or semi- 

 tropical species, M. monotropida Stal and M. c-nigrimi Champion, 

 are well characterized and illustrated by Champion in the Biologia 

 Centrali-Americana (Rhynch., Vol. II, 1898) and the only Nearc- 

 tic species, M. laheculata, was described by Uhler in North 

 American Fauna, No. 7, 1893. Two new forms are added here- 

 in, one from Texas and the other from Colorado. I am indebted 

 to Mr. Edmund Gibson, National Museum, Washington, D. C, 

 who has very kindly sent me the description of M. ehrethice to be 

 included in this paper.
