412 ADDENDA. 



Vandyke brown, the outer portion pale. Wing-cases 

 green, ribbed as usual, mottled slightly in two shades, 

 but not strongly contrasting; abdomen with each joint 

 gray (tiie gray of the w^hole pupa a more sordid white 

 with a gray tint, as there is none of the dark gray about 

 it), slightly green tinted, the incisures more distinctly 

 pale green, each joint with its row of small black spots 

 across the middle, supplemeuted back of the row with a 

 less perfect row of smaller spots, the first row of six 

 spots, of which the outer spot on each end of the row is 

 the black spiracle ; cremaster brown, elongated hooks 

 at the end that fasten into a thin, loose button of silk. 

 Duration of this period eight days. 



The larvse, when ready to pupate, folded a leaf to- 

 gether and loosely fastened it with silk, but there was 

 no lining of silk except a small, thin button to which 

 the cremaster was attached. 



The eggs were sent me by Dr. C. Hoeg, of Decorah, 

 Iowa. At first he sent me two eggs under date of July 

 81, 1897, that he had found on Malva Rotundifolia. 

 These did not hatch on account of injury in transit, aud 

 under date of August 6 he sent me fifteen more found on 

 the same plant. These hatched out August 12. I fed 

 them first on a species of Abutilon, but as they did not 

 take to that readily, though eating a little, I changed to 

 Althea Rosea. I think they will eat any of the rough - 

 leaved Malvaceae readily. On account of being away 

 from home part of the time, the larvae were somewhat 

 neglected in the last stages, but notwithstanding this two 

 passed through all their stages, producing the first imago 

 September 12, 1897.
