Notes on Eupithecia t with descriptions of new species. 

 By John A. Grossbeck. 

 The hitherto much neglected genus, Eupithecia* has sud- 

 denly been the subject of considerable study by lepidopterists, 

 working more particularly in the Geometridae. My own studies 

 were directed to it because of my inability to identify specimens 

 for correspondents, so after consultation with Mr. R. F. Pear- 

 sail, of Brooklyn, we agreed to jointly work over the group, 

 paying special attention to the eastern species. Mr. Pearsall's 

 collection contained quite large series of a number of species, 

 taken for the most part in the Catskill Mountains, and we were 

 fortunate in securing for study the material in the collections 

 of the American Museum of Nat. Hist., New York, through 

 the courtesy of Mr. Wm. Beutenmuller ; that in the Academy 

 of Natural Sciences, Philadelphia, through Dr. Henry Skinner, 



* Tephroclystia of our lists.
