It then starts on another twig, going to the tip and eating downward 
as before. 
Aug. 17, 9 A. M. Larva has increased to 30 mm. long. 
Aug. 18, 9 :30 A. M. Larva has increased to 35 mm. long. 
Aug. 19, 8 :45 A. M. Larva has increased to 40 mm. long. 
Aug. 20, 9 :40 A. M. Larva has mcreased to 45 mm. long. 
Aug. 21, 9:30 A. M. Larva has not increased or changed. 
Aug. 22, 9 :30 A. M. Larva now lies on the top of the cage, 
attached by its posterior end to a little pad of silk. It has curled up 
somewhat and only measures 27 mm. It still has the power to throw 
out its filaments when irritated. It lies as a long triangle, the head 
part thicker than the back. 
Aug. 23, 9:30 A. M. No change. 3 P. M. I saw the last stage 
of the larva changing into a pupa. The last part of the larval skin 
was on the posterior end of the pupa, which, after repeated jerks, 
pushed it off. The pupa was very light green, with yellow on the 
posterior abdommal region. It was held to the top of the vivarium 
by a pad of silk on its posterior end and by a silken girdle placed 
where the thorax joined the abdomen. The girdle was attached on 
both sides to the supporting top. 
Aug. 24, 9 A. M. No change. Pupa measures 30 mm. 
Sept. 5, 12:30 P. M. The butterfly has come out of the chrys- 
alis. I was unable to see this done. The empty case is still attached 
to the top. The butterfly is a male Papilio ::olicaon Boisduval. 
During the whole life history I found only two shed skins ; one 
when the larva radically changed color on Aug. 15th, and the other 
when the larva changed into a pupa. The shed skins and the butter- 
fly are in my collection. Raoul M. May,
