nal, runs slightly inwardly below costa, theu outwardly over the in. 

 nervules, where it is slightly interspaceally dentate; thus, in its upper 

 half it is sinuate or somewhat S-shaped. At 4th m. nervule it runs, as 

 ususal, inwardly, thence transversely to internal margin. The fringes 

 are dark, concolorous with the terminal shade. A single line crosses 

 the secondaries, projects over the disk, and corresponds to the external 

 line of the primaries. A distinct discal spot. Apical angle shaded with 

 plumbeous; fringes pale. Beneath whitish, iridescent, markings of 

 the upper surface faintly reflected. Legs white; anterior and middle 

 femora marked with black. Palpal tips, front and vertex, and sides of 

 thorax in front, dark. Thorax clear yellow. Abdomen above yellowish, 

 with a dark dorsal shade ; beneath, the body parts are white. Hind 

 legs entirely white, with two pair of unequal spurs. Expanse, 30 mil. 

 August. Type in Museum Peabody Academy of Science, Salem, Mass. 

 Kecalls the figures of Uulepte eoncordalis of Hiibner. The fringes on 

 primaries are not checkered, however, and there are other differences; 

 besides, the present is a stouter form. A specimen of this species has 

 been sent me by Mr. Schwarz, taken at Enterprise, Ela., on June 22. 



61. Botis anticostalis Grote, Can. Ent. 3, 104. 



Bright yellow, with deeper ocherous tinges. The species has th6 

 markings and appearance of Botis plumhicostalis. Costa of primaries 

 broadly plumbeous, but shading to yellowish toward the tips. Ordi- 

 nary spots larger, annulate, freer from the costal shade; their centers 

 are whitish-iridescent; the S has no orbicular; in Its place, the tegument 

 is somewhat pellucid and impressed. The two transverse lines are fain- 

 ter and wider apart, the transverse exterior differently shaped. This is 

 outwardly rounded at costa, where it is twice interspaceally lunulate, 

 and there is always here a narrow space between it and the terminal 

 dark shade. This latter fills in the entire terminal space superiorly 

 (except as above mentioned) between the external line and the margin, 

 but is obsolete inferiorly below 3d m. nervule, appearing as a spot at 

 internal angle. Secondaries with a distinct discal spot and single, flexed, 

 transverse line. Apices with the commencement of a dark terminal 

 shade. Fringes on both wings pale. ^ abdomen pointed at the tip, 

 elongate, with dark dorsal shade; 9 yellow above. Thorax yellow; 

 head, palpal tips, sides of thorax before insertion of wings, dark, as in 

 B. plumhicostalis. Legs whitish; anterior and middle pair shaded with 

 blackish. Expanse, 25 mil. July, August. Types in Museum Peabody 

 Academy of Science, Salem, Mass. 



Smaller than B. plumhicostalis, but greatly resembling it at first sight. 

 On a comparison, the differences above detailed are quite apparent. 



This species may belong to Crocidophora. I have not seen the male 

 since I described the species in 1871. My types were sent to the Pea- 

 body jMuseum, but they have not been well cared for. The type of the 

 preceding species has been badly eaten by larvse, and of the present I 

 have been only able to see the female.
