204 EHOPALOCEEA. 



Hal. Panama, Veraguas (Arce).— Colombia 2 ; Venezuela 12 . 



Two male specimens of this species were contained in Arce's collection sent from 

 Veraguas. These agree closely with the Venezuela type, though the submarginal 

 whitish spots beneath are almost obliterated. The species most nearly allied to 

 P. lepidus is P. crassus, a butterfly of wide range in South America ; from this it differs 

 in its shorter and darker wings, and in having the ochraceous spot confined to the 

 female only and not common to both sexes, as is usual in most specimens of the allied 

 species.

Hal. North America 3 , from the lakes southward, and westward into California 8 . — 

 Mexico 5 , Northern Sonora {Morrison), Presidio de Mazatlan (Forrer), Acapulco (A. 

 H. Markham, H. H. Smith), Dos Arroyos in Guerrero (H H. Smith), Pinos Altos in 

 Chihuahua and Rio Mescales (Buchan-Heplurn), Jalapa (Hoge), Coatepec (Brooks), 

 Orizaba, Cordova (Salle), Puebla (Richardson), Atlixco (F. D. G.). 



The history of this species has recently been very minutely gone into by Mr. Scudder 

 in his work on the ' Butterflies of the Eastern United States and Canada ', where will be 

 found full descriptions of all its stages of development as well as its habits and distri- 

 bution within the limits of the United States. On the Mexican side of the frontier it 

 is widely distributed as far south as the State of Puebla. On the eastern side we have 

 no record of its occurrence at a lower elevation than 4000 feet, but it is found on the 

 shores of the Pacific near Acapulco and Mazatlan. Its range in altitude is therefore 

 very considerable, and extends from the sea-level to a height of about 7000 feet in the 

 mountains. 



Some variation is noticeable in Mexican specimens. This principally affects the 

 submarginal spots in both wings; these are sometimes obsolete, at others clearly 

 defined ; some females, too, are of a more sooty hue, due perhaps to age and exposure, 

 others are brighter and greener.
