This insect is generally observed in summer when it appears as a 

 dirty white, woolly and powdery mass, more or less oval in shape 

 and about one-fourth of an inch in length (Fig 2, a.) Atone end of 

 the mass, which consists of waxy threads secreted from the back of 

 the insect, together with about five hundred eggs, is the shriveled 

 body of the female. These eggs are light yellow in color, a little less 

 than half a millimeter in length and about half as wide.

The young females are pale yellow and the males red. The 

 female is long and oval in form, slightly tapering toward either 

 end. The antennae (Fig. 3, e) which are six-jointed have the 

 last joint the longest and about equal in length to the three preceding 

 combined. The second joint is slightly longer than the third, fourth 

 or fifth. In front of the antennae the head bears several slender 

 hairs. The eyes are dark purplish, and in front of each is a single 

 short spine. The prothorax has three similar spines, while all of the 

 remaining segments except the last have one each. The anal lobes 

 have two or three spines and one long slender bristle. The adult 

 male (Fig. 3, c.) and the male larva are yellowish red. 



When the young larvae are hatched they spread over the leaves and 

 by means of the sucking proboscis or mouth parts, with which they 

 are equipped, extract the juices. The males cease to feed about
