ing complex tubercles ; while the third differs from the second 

 mainly in bearing more compound tubercles which are darker, 

 the presence of median and dorso-lateral stripes, in being 

 deeper green in general coloration and the generally darker 

 appearance to the unaided eye. 



At Paris, Texas, in 1904, this species became increasingly 

 numerous toward late fall (early November) in scattered 

 situations. 



9. Anosia Plexippus Linn.: Length of Pupal Stage (Lepid.). 



On June 2, 1902, at Blacksburg, Virginia, two chrysalids of 

 this species were formed in the laboratory; the resulting but- 

 terflies emerged late in the afternoon of June n, or after a 

 stage of about nine and a quarter days. The butterflies lived 

 in confinement without food until June 20, when they were 

 liberated. 



10. Ceratomia catalpae Boisduval (Lepid.). 



An egg mass of this species was found upon the under sur- 

 face of a leaf of a catalpa tree at Blacksburg, Virginia, May 

 26, 1902; the eggs commenced hatching on June 4 following. 

 There were at least five hundred eggs in the mass but they 

 were not counted. 



11. The Pupation of Euvanessa antiopa (Linn.) (Lepid.). 

 A closely clinging mass of caterpillars of this species in 



about the third larval stadium was obtained at Blacksburg, 

 Virginia, July 30, 1902, from a willow tree. They molted on 

 August 4 and again on August 8, and by August 14 were full 

 grown ; on the following day one chrysalid was formed while 

 eight of the caterpillars had suspended themselves for pupa- 

 tion. Of these latter, only three successfully transformed 

 three fell to their death while trying to attach the cremaster 

 (the other two were accidentally killed). On August 16, other 

 larvae had suspended themselves. The following notes were 

 made : 



(i) One suspended larva, August 15, 1902: 



Integument parts along dorsum 10:31^ p. m. 



Chrysalid excluded excepting anal segment 10:34^ p. m. 



Anal segment excluded 10.35 P- m 



(Struggle to attach cremaster began at once.)
