not certain what the dominant element or 

 factor is. It may be female Brown Leghorn 

 color, a modifier, or femaleness or something 

 else. As females colored nearly like Brown 

 Leghorn females appeared among black fe- 

 males in Fj from Brown Leghorn males by 

 White Eock females it suggests that the domi- 

 nant element is not female color. 



A similar inference may be drawn from the 

 distribution of color in the buff and black non- 

 barred Fj females from White or Barred 

 Eock females by Buff Eock male. Some of 

 these are black with orange hackle and grade 

 into others in which buff predominates. In 

 all cases the colors are distributed in a more 

 or less perfect imitation of the pattern of 

 Brown Leghorn females. Moreover, many of 

 these hybrids are stippled in certain regions 

 which always correspond to the regions in 

 Brown Leghorns which are stippled.

 time during its history. 



The following officers were elected for the en-

 mal College, Greensboro.

 joint meeting at which Dr. E. A. Hall, of the 

 University of North Carolina, read a report on 

 "The Chetoical Eesearches of Ehrlich Leading

 papers on the program, all of which were read 

 save two, and all read when called for but two. 

 In attendance, number of papers presented, gen- 

 eral interest as evidenced by the discussion of the 

 papers, this session excelled any in the history 

 of the academy. In addition to the presidential 

 address, which is published in full in the current 

 number of the Journal of the ElisJta Mitchell 

 Scientific Society, and to the lecture on Sirius, 

 the following papers were presented: 



Catching Sawlc Moths on Flowers at DusTc: C. S. 



Brimlet, Ealeigh. 



This paper tells the author's experiences in 

 catching hawk moths on flowers at dusk in several 

 years at Ealeigh, N. C. The flowers first experi- 

 mented with were jimson weed, afterwards four- 

 'clocks. With the jimson weeds it was found 

 that tying the flowers in bunches was an advan- 

 tage, while this did not apply to the f our-o 'clocks, 

 as they were already in bunches. Two flights of 

 moths were noted, the first in June, the second 

 in July and later, the latter largely, the former 

 wholly composed of moths from over-wintering 

 pupae. The proportion of sexes visiting flowers 

 was 5 males to 2 females. A neighbor's cat was 

 found to be as expert a catcher of hawk moths 

 on flowers as the author. The notes apply mainly 

 to the two tobacco hawk moths.
