Butterfly.—The blue of the upper side of the male in the plate is too dark; but the female and the under side of the wings are accurately delineated. The species is generally tailed, but specimens without tails occur. Expanse, 1.00-1.10 inch.
Early Stages.—These are well known and have been fully described. The caterpillar feeds on leguminous plants.
This delicate little species ranges from the valley of the Saskatchewan to Costa Rica, and from the Atlantic to the foot-hills of the Western Cordilleras. It is common in the Middle and Western States, flitting about roadsides and weedy forest paths.
