from view. Maturity is probably reached toward the last of ]\Iay and the 

 wingless females deposit eggs for another brood. Winged females are 

 produced about the first of June. There are several broods during the 

 summer and the winter appears to be passed in some years, at least, by 

 wingless females which commence feeding toward the latter part of March 

 and begin to deposit eggs in early April. These hatch about the 15th and 

 young begin to attach themselves the 26th. The wingless females disap- 

 pear about ]\Iay i, and hatching ceases by the 7th ; winged adults appear 

 about the 9th, by the 17th all the young are attached, and by the 23d the 

 winged adults disappear. These latter records are based on observations 

 made by Mr Storment. He further states that this species may have an 

 alternative food plant which at present is unknown. 



Description. The eggs occur in downy balls near the bases of the 

 needles and var\- in number from 5 to 60 or more in each, usualh' there are 

 only a few. They are oval, dusky or reddish yellow, slightly ovate, about 

 .34 mm long and with a transverse diameter of . i 7 mm. 



The young of the winged form, as described by Professor Osborn, are 

 oval in shape, flattened, yellowish or light brown. The antennae are three 

 jointed, the first short and thick, the second slightly longer and not so thick 

 and the third is three times as long as the first and half as thick, and set 

 with a few stiff hairs at the apex. As these young develop they become 

 darker in color, assuming a deep red or brown and finally become almost 

 black. The woolly substance is thick on the abdominal segments and also 

 on the meso- and meta-thorax, hiding the insect and changing its appearance 

 to that of a ball of white down. 



The winged form, as described by Professor Osborn, is light reddish 

 in color, and the wings are very white, expand rapidly and become 

 transparent, while the body darkens till almost black. The antennae are 

 five jointed and short. The tarsi are one jointed, with a rudimentary first 

 joint and two claws. The forewings are folded rooflike over the body, the 

 anterior pair having a strong subcostal vein which is branched at the basal 

 third, the lower branch running parallel for a distance and then turning 

 obliquelv toward the posterior margin. From this branch there are two 

 oblique discoidal veins running to the posterior margin. The stigma is 

 indistinct. The wingless female is enclosed in a woolly mass which adheres 

 to the bark. The legs and antennae are persistent, small, the latter being 

 three jointed and the tarsi one jointed and terminated by a pair of claws.
