NO. 7 THE GOLD-BANDED SKIPPER CLARK II 



Furthermore, though it is generally common in Mexico and in the 

 mountains of southern Arizona, in the eastern States, though widely 

 distributed, it is very local, occurring at widely separated stations 

 almost exclusively in hilly or mountainous regions where it is found 

 in small numbers — indeed from many localities there is only a single 

 record. It is true that its habits are such as to cause it easily to be 

 overlooked, yet if it were anywhere really numerous in the eastern 

 States, or if it were generally distributed, this certainly would be 

 reflected in the records. 



Most of the specimens in collections are from Arizona or Mexico. 

 No collection contains a long series of eastern specimens, nor more 

 than a very few eastern examples from any one locality. 



The explanation of the distribution of the gold-banded skipper 

 would seem to be that its true habitat is in Mexico and the mountains 

 of southern Arizona, where it is locally a common permanent resident. 

 In the eastern States it is a casual resident of erratic and fortuitous 

 occurrence, maintaining its foothold by virtue of constant new arrivals 

 from the southwest coupled with redistribution from local more or less 

 permanent centers ; though constantly present, it cannot properly be 

 regarded as an endemic species in this area. 



We believe its status to be parallel to that of Sfrymon Ontario 

 Ontario, which appears to be frequent about St. Louis, Mo., but 

 farther east and northeast merely an erratic causal visitor.

Diagnosis. — " Normal specimens of cellus and pseudocellus are 

 black, or nearly black. The black on this specimen, including the an- 

 tennae and body parts, is replaced by bronze-brown. The band of gold
