(After Comstock.) ^?Efffj.—I have not seen the eggs of this species, excepting those takenfrom the body of the female. And as I have repeatedly found younglarvae under the scales I am led to believe that the species is vivipar-ous. ^^ Scale of Male.—The scale of the male resembles that of the female,excepting that it is only one-fourth as large ; the posterior side is pro-longed into a flap, which is quite thin ; and the i)art which covers thelarval skin is olten lighter than the remainder of the scale. ?Male.—The male is light yellow, with the thoracic band brown, and6521 o I 3 34 INSECTS AFFECTING THE ORANGE. tbe eyes purplish black.
