. Economic entomology for the farmer and fruit-grower [microform] : and for use as a text-book in agricultural schools and colleges . Grapta prognc.—Wings of right side detached to show under side; this is almost like G. comma. We have many species of considerable size belonging to the genus Argyiinis, which resemble each other more or less by their tawny upper sides Fig. 254. martced with black spots, and by having the under sides more or less marked with silvery blotches, es- pecially on the hind wings. None of themare injurious, the larvae feeding upon vio- lets. In the genus Grapta there are species with strongly and irregularly angulated and toothed wings, quite dark brown in color, with irregular black or blackish blotches, spots, and lines, and a little silvery mark resembling a comma or semicolon on the hind wings beneath. Of these the caterpillar of G. comma feeds upon the hop-vine, although it rarely does any serious injury. It is reddish or yellowish in color, with a black head and black branched spines, and forms an angular chrysalis which is suspended by the tail. The chrysalis is yellowish green in color, with prominently marked segments, and has the thorax produced into a somewhat acute process. Another very common, almost cosmopolitan butterfly, is the Vanessa antiopa, popularly known as the "; It is of a very dark, rich-brown color, with a broad yellowish border on both wings. It winters in the butterfly stage, and may often be seen on warm days in midwinter, fluttering about in the woods, while it is the earliest of the butterflies to make its appearance in spring. The caterpillars feed upon quite a variety of plants, notably willow and poplar, and often in great colonies. When full grown they are two inches or more in length and black, with red-marked, branched spines. The chrysalis is suspended by the tail, and of a somewhat mouse-gray color, the segments marked with acute spines. This may under circumstances be- come a
