together on dorsum at base of caudal horn. Granulations of 

 whole body very distinct. Stigmata bordered by glaucus : 

 under lense each stigma, save first, shows a central whitish 

 space. 



4th moult. June 2oth, noon. Length i^ inches long ; head 

 bluish green. Viewed dorsally glaucus whitish above ; a central 

 and two lateral bluish lines ; below each of latter a yellowish 

 white line separating glaucus of dorsum from green-yellow of 

 sides ; dorsum wtth fine white-green granulations ; under sur- 

 face wine color from rear to beginning of 5th segment, rest of 

 central surface brown-purple. Dorsal horn black, yellow at 

 base of sides, covered with shining black spinules. A yellow 

 granulated dorsal collar on first segment behind head. Stig- 

 mata encircled with greenish white ; black, deepest in center 

 (opening ). 



June 24th. Discoloration prior to pupation beginning to 

 show ; larvae now i T 9 7 inches long. Colors as last described. 

 The pupal discoloration, starting at 3 P. M., began by a 

 gradual dimming of the colors and a widening of the dorsal 

 stripe, which becomes a dirty olive ; this color gradually 

 spreads over the whole dorsal field ; by 9 P. M. the discolora- 

 tion was complete and the dorsal space was wine-colored ; this 

 larvae then began to hunt for a place to pupate. By June 25th, 

 7 P. M., each in this cage had spun a loose brown-purple web 

 enclosing the larva and attached to leaves, gravel, etc., in the 

 bottom of the cage ; a few spun among the leaves of the food 

 plant ; none entered the earth. June 29th, pupation complete. 



The above descriptions apply to eight larvae, separated from 

 the rest and kept on my study table in a glass-covered box ; 

 the rest were in a regulation breeding cage out on the piazza, 

 subject to the cool nights, and were a week behind in pupation. 

 This seemed to make no difference in the imagines, the eight 

 indoor ones giving seven diffinis and one fft/ira, and those 

 outside being various in their forms, mostly true diffinis and 

 one or two at lira. These commenced to emerge on July 12, 

 continuing up to the 2oth, and I have about fifteen pupa, yet 

 alive and healthy, and which will probably winter. I have 

 never found them on any plant but Triosteum perfoliatum.
