11. Notes on Rearing Moths From the Larvae: 



C. S. Brim ley , 



The experience of several years shows that caterpillars 

 of moths, such as the Grape Sphinx (Ampelophaga 

 myron) and the Ash Sphinx (Ceratomia undulosa\ 

 whose food is not succulent, may be more easily 

 reared in closed jars than those which feed on 

 succulent leaves, such as Tomato Worms (Phlege- 

 thontius Carolina). Hawk moths are often attacked 

 and killed both by Braconid flies and Tachina flies. 

 The larg-e Sphinx of the grape (Pholus pandorus) is 

 even more persecuted by these parasites, and the 

 Tomato Worm is much troubled by the Braconids. 

 The common Ash Sphinx (Ceratomia undulosa) and 

 Grape Sphinx (Ampelophag-a myron), however, are 

 seldom molested. Five larvae of the Myron Sphinx 

 of the grape obtained in August all transformed into 

 pupae on consecutive days; two of these produced 

 moths in about sixteen days after transforming; the 

 other three overwintered; two of the latter died, but 

 the third produced a moth almost exactly nine months 

 after it had pupated — taking about fourteen times as 

 long to emerge as the first two. Tomato Worms and 

 some other insects show similar peculiarities in 

 pupation. 



NIGHT SESSION. 



The night session of the Academy was held in Leigh Hall. 

 The address of welcome was made by Prof. Jno. F. Lanneau 

 and the response by Prof. Collier Cobb. Dr. Baskerville, 

 President of the Academy, then gave his retiring address, the 

 subject being: "Science and the People." At the conclusion 

 of the address the Academy was tendered an informal recep- 

 tion by the ladies and faculty of Wake Forest College. 



SATURDAY MORNING SESSION. 



The Academy was called to order by President Baskerville 

 and proceeded at once to the presentation of papers, as
