the males and about half of the females are dark g-rayish 

 brown, with a distinct and conspicuous pattern of bands and 

 mottlings of a much darker shade ; in a few specimens this 

 pattern is almost obliterated by the general infuscation of the 

 ground color.

 grassy margins of woods ; in openings in the oak dune woods, 

 among the low herbaceous growth; and on the bare soil of 

 roads and trampled areas in dry pastures. Specimens were 

 washed up in the beach drift several times. 



The coloration of this series shows a large amount of varia-
