NEOTROPICAL MICROLEPIDOPTERA, VII 



NEW GENUS PSEUDOMERITASTIS AND ITS SPECIES 

 (LEPIDOPTERA: TORTRICIDAE) ' 



By Nicholas S. Obraztsov 



Three species of the Tortricidae of the Neotropical fauna— I'o^wto 

 Meyrick, cordigera Walsingham, and heliadelpha Meyrick — were 

 placed by Edward Meyrick in the genus Meritastis Meyrick, and 

 cordigera was treated as a synonym of volufa. The present author 

 had the opportunity to reexamine these species which he accepts; his 

 review of the materials disclosed four undescribed species belonging 

 in the same relationship. His studies have shown that cordigera is a 

 separate species and that the entire group requires the recognition of 

 a new genus, having little in common with Meritastis. 



In this paper the author establishes the new genus, describes four 

 new species, and gives information on the species formerly known. 

 The author acknowledges with thanks the kind assistance of Dr. J. F.
