Fig. 4S. — The Pinp-Ieaf Chermes, Chermes pinicorticis — the larva, the winsless female, and the 

 winged form (male '{). 



The time required to attain tlie mature form has not been recorded, 

 but the change probably occurs toward the last of May. The female des- 

 tined to continue the species by laying eggs for another brood may be 

 recognized by being without wings, of an oval form which becomes 

 pyriform durinjj egg-laying, with legs proportionally longer than in the 

 larval stage (see the enlarged view), and three-jointed antennae. The lower 

 right-hand figures give upper and lower views of the female. From her 

 oviposition, a second brood results, which is followed by others, at un- 

 known intervals until some time into the autumn. 



In one particular, the first brood differs from the later ones, in that 

 it embraces a winged form. During the latter part of May, individuals 

 are to be found showing the pupal stage, by being provided with wing- 

 pads — otherwise they resemble the larvae. The thorax is reddish, the 

 abdomen of a darker red, the wing-pads yellowish, and a little of the 

 woolly material adheres to portions of the body. 



They continue in this stage but a few days, until about the first of 

 June, when their outer encasement parts asunder, and the winged form 

 issues, the appearance of which is shown in the figure. The antennfe 

 of these are five-jointed, the body is almost black, and the four wings
