180 THIRTIETH REPORT ON THE STATE MUSEUM. [68] 



of the anterior wings is perfectly visible, and that of the 

 posterior pair, indistinctly. 



Five days after pupation (August llth), the following 

 changes were noticed. The eye-cases had become purple ; 

 the wing-cases were whitish, perfectly relieving the nervula- 

 tion; the abdomen green except at its tip where it was brown. 

 The antennso folded over the eyes, cutting off a small section 

 of their upper portion, have the club brown, and showing the 

 joints ; the posterior leg-cases show numerous brown spinules 

 on the inclosed legs. 



On August 12th, a few hours before the escape of the butter 

 fly, the chrysalis was brown, except at the abdominal incis- 

 ures, where it was green and of a transparency disclosing 

 some of the internal organs. The white annulations of the 

 antennal joints were visible, and through the \ving-cases could 

 be seen the gray scales of the margin, the disk and the cilia 

 of the wings. The butterfly emerged in the afternoon of the 

 12th. 



From two other larvae which had been reared on Aquilegia 

 canadensis* and changed to chrysalis on the 8th and 9th of 

 August, butterflies were obtained on the 15th, giving for the 

 length of pupation of the three examples, six, seven and six 

 days respectively. 



* The following captures in the field of N. Lucilius were made 

 during the year (1870) when the above notes were taken : May 

 16th, at Bethlehem, Albany county, 3 &amp;lt;$ s ; May 21st and 31st, 

 one 6 each, at Center; July 6th, 9 3 s at Bethlehem, and 

 another at same locality on the 28th ; and others again on 

 August 26th, and September 9th and 14th at the same place. 



On August 25th and 28th, five butterflies were obtained 

 from larvae which had been collected at Bethlehem. So late 

 as September 9th, larvae just emerged from the egg were taken, 

 associated with others about half-grown. 



There are two annual broods of this butterfly, and possibly 

 a third.
