RESULTS OF THE YALE PERUVIAN EXPEDITION OF 1911. 



LEPIDOPTERA. 



By Harrison G. Dyar, 



Custodian of Lepidoptera, United States National Museum. 



A large part of the species of Lepidoptera could not be found in 

 the collection of the United States National Museum at Washington, 

 and I accordingly enlisted the aid of Mr. William Schaus, who very 

 kindly compared the specimens in London. He submitted certain 

 specimens to various specialists, to all of whom my thanks are cor- 

 dially extended. The collection contains 242 species, here listed.

 divided, white in the male, yellow in the female, white edge of the 

 wings very broad in the incisures between the veins. Otherwise as 

 in P. m. cMorodamas Guenee.

Mr. Schaus notes that the specimens are "very near manco.'* 

 From the manco in the collection they differ in the whiter ground 

 color and reduced submarginal dark band of hind wings, but the differ- 

 ences are not marked.
