by the artificial conditions, another condition was supplied in this 

 manner. A peach tree about ten years old having plent}- of foliage 

 and a heavy trunk was cut back to permit one of the cages being placed 

 over the tree. This, then approximated natural conditions in every 

 way except that the moth number four was in confinement (Plate 

 11, Fig. 2). 



July 27. All eggs hatched in cage B. The hatching occurred either 

 during the night or very early morning and w^as not observed; the 

 larvae emerged from the micropyle end, cutting out the entire end 

 in small sawdustlike particles. Cage B was then moved over four 

 other trees. 



Female No. /+, July 25. At 9 a. m. two females, numbers four and 

 five, and one male were put in cage C. At 9.55 two males were flying 

 about the cage, one of which was caught and introduced; at 10.15 a 

 second visiting male Avas placed in the cage and at 10.22 a third was 

 secured. At 10.24 one pair was in coitu, remaining on the branches 

 and leaves until 11.45 when they separated. At this time female 

 number five, not having copulated, was removed from the cage. In 

 this case, as before, the males appeared only when the female extruded 

 her ovipositor, flying away when she sheathed same. At 1 p. m. two 

 eggs were found on a bark scale just above the ground and one egg 

 about eighteen inches above. 



July 26. Female number four not in the cage, presumably died 

 and was eaten by ants. She deposited fifty-six eggs on the leaves 

 and twenty-three on the trunk. 



August 4- Seven eggs in cage C hatched between 4.30 p. m. August 

 3d and 7.30 a. m., August 4th. Larvse could not be found, even with 

 the aid of a large reading glass. 



August 5. Cage C was watched carefully until dark on the 4th, but 

 on visiting the cage at 7.30 a. m. on this date, all eggs were hatched. 



Female No. 5. This moth was not used. 



Female No. 6, July 27. At 1.30 one female, number six, was intro- 

 duced into cage B with one male. At 2.10 one male appeared; at 2.15 

 one male was introduced; at 2.45 another male was introduced and at 

 2.50 a fourth male was placed in the cage. No copulation. 



July 28. At 11 and 11.30 males were placed in cage B. At 11.40 a 

 pair were in coitu, separating at 1 p. m. 



July 29. Forty-two eggs on the trunk of one tree in cage B, the first 

 egg eight inches from the ground; last about eighteen inches. Six- 

 teen eggs found on the leaves. 



August 1. Female dead. She deposited a total of ninety-seven eggs, 

 forty-two of which were on the trunk and fifty-five on the leaves. 



August 1. Eggs on trunk of tree in cage B had their top half eaten
