NO. 1337. REVISION OF THE GENUS LEPIDOPA— BENEDICT. 891 



The Hippidffi and the Albuneidae make up the super-family Hippoidea 

 of the Maerura Anomalia. 



In this paper four species are described as new, and, though the 

 material is scanty, the localities from which the specimens were ol)tained 

 are separated by long- distances. Of the seven species now included in 

 the genus Lepidopa six are represented in the collections of the U. S. 

 National Museum and one in those of the museum of Union Univer- 

 sity, Schenectady, New York.

The Albuneids of this genus may be immediately recognized by the 

 verv long stiff lashes of the anteunules or middle antenna^ in connection 

 with the broad scale-like stalks which range in form from ovate to 

 quadrate. The carapace in all species is shield shaped, the surface is 

 but little broken by lines. 



The characters relied upon to distinguish the species are believed to 



be those least likely to vary.
