70 THE CANADIAN ENTOMOLOGIST. 



is important to refer to the synonymy, since they have been always 

 (-on fused. 



In 1862 Harris described the Columbine feeder as Gortyna 

 leucostigma, (Ins. Inj. Veg.,p. 440), but this name was preoccupied. 

 Grote and Robinson advanced the name purpurifascia in 1868 

 (Trans. Amer. Soc, vol. I, p. 341), describing from two specimens, 

 and they clearly had both forms before them. They first, and at 

 much length, described the Columbine form, a female, and their 

 figure (plate 7, fig. 51), confirms what they clearly intended as 

 representing their species. They described their other specimen, 

 a male, last and in a few words, noting," however, the differences 

 of ornamentation that are distinguishing features between the two 

 forms. While it seems very clear, lest future questions arise, the 

 name purpurifascia G&R, is herewith restricted to the above- 

 mentioned female type of their description. This will accord 

 agreeably to later interpretations and uses of the name, in the more 

 important references where figures have been given. Slingerland, 

 Can. Ent., vol. XXIX, 161 ; Holland, Moth Book, pi. XXVI, 

 fig. 7; Hampson, Cat. Lep. Phal. Br. Mus, pi. CXXXVIII, fig. 25, 

 all figure the Columbine borer as purpurifascia. 



For the Loosestrife borer the following specific name is proposed : 



Papaipema lysimachiae, n. sp. 



Size small, form and pattern typical, sexes similar. Head 

 reddish purple, white scales at base of ciliate antenna; thoracic 

 I lifts and patagia 1 edged in deeper purple. Abdomen of the luteous 

 yellow of the secondaries, the tufts minute. Primaries rich yellow 

 powdered with red brown, the basal, subterminal and median 

 shade lines defined with the latter colour, and of usual delineation, 

 the post median line double, the inner very finely drawn with red 

 brown, the outer rather fasciate, dark purple or blackish, its course 

 inwardly oblique and quite rigid after a sharp turn below the costa; 

 subterminal line lunulate, fine, outwardly dentate on veins, empha- 

 sized as defining the glistening purplish subterminal space from 

 the redder terminal area; a marginal line at base of purplish cilia. 

 Basal spots, median field and apex of the bright yellow ground 

 colour, the inner basal area and subterminal space reddish purple, 

 the latter darkest and rather iridescent, but contrasts are not 

 strong. The orbicular and double claviform show as three super-
