HESPKRIDI: THE GENUS THORYBES. 1423 



specimens :ire invariably worn ami battered. They deposit tlicir eggs in 

 the latter part of June when the biittei-flies are most al)undant : mine were 

 laid June 25 and 2(> ; they hatch in a week and tlie caterpillar grows slowly 

 in no more than time to reach chrysalis before the end of the season. In 

 West Virginia, Edwards obtained eggs on June 4, wliich would seem to 

 give still ample time there for a second brood of butterflies, though this is 

 not certain ; but al)out the middle of July the butterfly becomes very com- 

 mon in Nashville, Tenn., and this must represent the second brood. 



Abbot says the butterfly frequents swamps, hummocks and oak woods. 

 I have always found them in open spots in woods on rocky soil, flying about 

 the blossoms of the butterfly weed, Asclepias tuberosa, and extracting 

 their sweets in company with Epargyreus tityrus and Atrytone zabulon. 

 They are also fond of the flowers of Phlox. 



Desiderata. The whole history and distribution of the butterfly are 

 but meagrely sketched above. We need to know more of the larval habits, 

 especially at maturity, no proper description of the chrysalis has been 

 published, and even the seasons are very inadequately known ; the features 

 accompanying the change from monogoneutism to digoneutism especially 

 need investigation. We are not even certain of the mode in which the 

 winter is passed. Nothing is known of the flight and postures of the 

 imago and very little of its haunts and habits.
