W Howe, North America butterflies

[Andres M. Sada]

I would like to buy a copy of William Howe's book on North American
butterflies (I do not know the exact title). If anybody would be willing to
part with their copy I would pay any reasonable price. Although published
not long ago, it is out of print.

Saludos
