NEW SPECIES OF SEMIOSCOPIS. 



BY HARRISON G. DYAR, WASHINGTON, D. C. 



The following species of Semioscopis (Epigraphia) seem undescribed. 

 They were sent for names by Messrs. F. A. and H. D. Merrick, of New 

 Brighton, Pennsylvania, and have been donated by them to the National 

 Museum. These new species closely resemble several of the European 

 ones, yet seem all specifically separable.
