. The butterflies of the eastern United States and Canada [microform] : with special reference to New England. Butterflies; Butterflies; Papillons; Papillons. 1196 THE BUTTERFLIES OF NEW al)scncc of those comparatively Inrge, conical wartlcts, ten or twelve times larj^er than the smaller ones, which form so conspicuous a feature in both F. napi and P. rapae, and which arc arranged at subequidistant intervals in a transverse row on each of the subsegmcnts of the l)ody ; they are present in P. oleracea, but are not nearly so large relatively as in P. napi, except possibly on the stigmatal subsections of the anterior part of the bt)dy, and are further inconspicuous in being either concolorous with the body, or white, or only a little infuscated, while in both the other species mentioned they arc piccous and most conspicuous; occasionally, however, when white, they are marked with a fusccus annulus around the base and so are made more conspicuous, but herein ti:ey approach the normal type of P. rajiae and not of P. napi. The duysalis of P. oleracea differs from that of P. napi of Europe, first, in tiie following stru<'tural features: the frontal tubercle curves distinctly upwai-d, as shown in pi. 84, fig. ')7, while that of P. napi is directed straight forward; the elevation of tlie suprastigmatal carina to a distinct, spinous, compressed tubercle on the sides of the anterior part of the third abdominal segment, is far more marked, and the tubercle itself distinctly Hares laterally, which tliat of P. napi cannot be said to do. Second, in colorational peculiarities: Ciirysalids of P. napi are far more heavily marked ; especially the suprastigmatal carina is interiorly with large, blackish fuscous patches, forming a more or less interrupted band over the second to the eighth abdominal segments ; the fourth to the tenth segments have a distinct, mcdiodorsal black dash at the anterior margin ; and tlie disk of the wing cases is marked with a double Id
