The average length of the male scaleis , and it is fully formed in about ten daj^s from hatching (,5). * Signoret informs me, after examiuing specimens sent to him, that it is probably the jyini of Har-tig, described in 1839 in tlie Jahresbcrichte ueber die Fortschritte der Forstioisscnschaft for that year. Nothaving access to the work, I am nnable to decide the point; but I know that a very similar, if not identi-cal, species occurs on the cultivated pines in England, as I have seen it on some trees in Mr. W. beautiful grounds, at Weighbridge. t N. Y. Reps. Vol. I, p. 256. OF THE STATE ENTOMOLOGIST. 99. The male louse (Fig. 36) may be seen by the well-trained eye,crawling over the needles and branches, and he may be found before the anal shield of any of the fe-^^ males begins to form. He has thesame size and structure as his ap-ple tree kinsman, and differs princi-pally in being of a uniform orange-red. The female scale averages length, and is completed in aboutthree weeks; the median part isa little darker than the larval, andthe anal shield has an even, whitesurface. It differs materially inform, according to the kind of pineit inhabits, being broader and morecurved on the broader-leaved spe-cies, (Fig. 35, d). but usually narrow, and with a very slight curve onone side, on the White Pine (Fig. 35, c). The female herself presentsvery much the same appeara
