AMERICAN LEPIPOPTERA. 83 



Lohophora atroliturata, Walk., p. 1710, belongs to Eupetliecia, and 

 has been subseqently described by us as Eupethecia geminata. 



In the Phalaenidae (^Geometrites), the generic determinations of 

 Mr. Walker are very generally erroneous. The material seems to have 

 been described under the genera without reference to coincidence of 

 structural character, or indeed to casual resemblance. Thus, while 

 Guen6e's Eurymene alcoolaria is correctly identified (probably from a 

 type specimen), a very similar and closely allied species figures twice 

 as an Epione, and again as an Ellopia, In the most difficult genera 

 (i. e., Boarmia, Tephrosia, etc.,) the descriptions are recklessly multi- 

 plied, and the material being very often in imperfect preservation, the 

 difficulty of ascertaining what is meant from the short descriptions, 

 usually unaccompanied by comparative remarks (which would be in- 

 deed often impossible to give, owing to the real specific identity of 

 many specimens described by Mr. Walker as distinct), is insuperable. 

 Specimens belonging in reality to only^t'c species of Boarmia are de- 

 scribed under tldrteen difierent specific names.
