This scale is represented in Fig. 5, natural si7;e; Fig. 5a, en-larged. * * * ??Egg.—The eggs are pale yellow. ^^ Scale of Male.—The scale of the male is about one-fourth as large asthat of the female; the posterior side is prolonged into a thin flap,which is gray in color; in other respects the scale appears like that ofthe female. (Fig. 5&, enlarged.) ??Male.—(Fig. 4.) Themaleislightorange-yellow in color, with the tho-racic band dark brown and the eyes purplish-black. It very closely re-sembles the males of A. aurantii, but differs from that species in being. Fig. 4.—Aspidiotusficus (Ashm.), male. (After Comatock.) a smaller insect, with shorter autennne, longer style, wider thoracic band,and with the pockets of the wings for the insertion of the liair of thepoisers farther from the body. Derelojymentofthe Insect and for rn at ion of the Scale.—Thedevelojimentof this insect from the egg to the adult state was followed through fivegenerations. I give, however, only the substance of a part of the notes THE RED SCALE OF FLORIDA. 29 taken ou a single brood—the second one observed—as that will be suffi-cient for our purpose. The observations were made upon specimenswhich were colonized on small orange trees in pots in my office in Wash-ington. The rate of the development of the insects Avas probably slowerthan would have been the case in the open air in Florida. April 12,1880, specimens of orange leaves infested by this scale werereceived from Mr. G. W. Holmes, Orlando, Fla. At this date maleswere found both in the pu
