genus Callopistria was founded by Htibner, in his ' Ver- 

 zeichniss bekannter Schmetterlinge, 7 for the reception of two 

 species, C. pteridis and C. juventina, from Europe and Suri- 

 nam respectively. In all probability C. juventina was only 

 known to Hiibner, as it certainly was to Walker, from 

 Cramer's figure ; and therefore C. pteridis (placed by both of 

 these authors at the head of the genus) becomes the type of 

 Callopistria. 



Eriopus, Treitschke, adopted by M. Guene"e for the same 

 group and considered by Walker to be synonymous with it, 

 had for its type E. pteridis^ and therefore is, without question, 

 synonymous with Callopistria. 



In the ' Proceedings of the Zoological Society,' 1881, Mr. 

 F. Moore founds two genera Methorasa for the reception of 

 Eriopus Latreilleiy Dup., and Cotanda for Eriopus placo- 

 doideSj Guen. 



A careful examination of structural characters reveals the 

 fact that the genus Callopistria as extended by Walker and
