Dothan Ala. in 1899, began to hatch the latter part of May, and a sending 

 from Knoxville in the same year was unhatched June 6. The secretion of 

 the egg sac and the deposition of eggs in the mass of wax and fibers com- 

 posing the sac began in Washington late in May and continued gradually 

 till the middle of June, young beginning to hatch on the 13th. The 

 recently hatched larvae are a pale yellowish color, with a slightly brownish 

 median line and dark purple eyes. July 31 the first molt occurred and the 

 young were still a very pale yellowish white color and almost transparent, 

 though a very few specimens were marked with a pale purplish spot near 

 the extremity of the body. The growth from this time till October, at 

 which time the second skin was cast in 1899, was very slow. The third 

 stage however was observed as early as June 26, 1898. The young had 

 deserted the leaves in 1899 by Oct. 15. They w-ere at this time of a pale 

 brownish yellow color, somewhat darker along the median line, and were 

 characteristically marked with a large reddish, almost crimson, medio-dorsal 

 spot on the prothoracic segment, and with a similar one just in front of the 

 anal cleft. The eyes were minute, black, and nearly twice as large as 

 before. Most of the larvae had settled for hibernation on the trunk 

 by Oct. 21 and then the sexes could be distinguished. The females 

 are recognized by their more broadly oval shape. At about the time the 

 migration to the twigs began, late in October, the great majority of the 

 young were located along the ribs on the underside of the leaves, though a 

 large number were also found on adjoining twigs, generally in and about 

 the forks, in excrescences or near buds or other projections. They run 

 about quite actively at this time in search of suitable places for hibernation, 

 and a delicate layer of waxy secretion appears which gives the insect a 

 somewhat gravish appearance. Nov. i, 1898, all the young had settled for 

 hibernation, and were of a considerable darker color, harmonizing well with 

 the bark. There was little or no change in their condition in December 

 and the same was practically true at the end of the following March. Males 

 and females were found April 8 on potted trees. The latter were of a dark 

 purple color with a yellow median ridge. The first male transformed to a
