made in Ploricla, and thus feel confident tliat the 

 species is valid. I illustrate here two other species, 

 which have heen considered varieties, but never by 

 myself; and it is probable, as proved in the case 

 of C. Ccelebs, that the writers who discussed these 

 species had really never seen them, and must have 

 been influenced by other than scientific motives in 

 what they published upon them. The list of species 

 I have described is as follows : — Retecta, Rohln- 

 souii, Flehilis, Levettei, Residua, dugiisli, Arkoucc, 

 Ileskei, JBeaulcma, Semirelicta, Coccinata, Verrll- 

 liana, Siibnata, Riatrix, Adoptlva, Habilis, Ccelehs, 

 Radia, Anna, Clintonii, Abhreviatella, Frederici, 

 Mira, Alabamce, Rr cedar a, Rulciola, Fratercula, 

 Chelldonla— in all 28 species. 



The species of Catocala may be arranged in 

 groups, from the colour of the hind wings. I have 

 arranged them in this way, giving the sections the 

 names used by Iliibner in the ' Verzeichniss,' in a 

 paper contributed to the Sixth Annual Eeport of 

 the Peabody Academy of Sciences, Salem, Mass. 

 The black-winged species {Mormonia of Hiibner) 

 should inaugurate the genus, and fall into two 

 series, from the colour of the fringes to the secon- 

 daries, which are either white or dusky. The orauge- 

 and yellow-winged species can hardly be kept sepa- 

 rate, as the colour of the hind wings varies to this 

 extent in a single species. In the colour of the 

 collar and fore wings, C. Conciimbcns, a species with 

 lovely pink hind wings, resembles C. Illecta, a species 

 with golden-yellow secondaries ; the little C. Trlstis, 

 the smallest species with black hind wings, rather
