104 THE CANADIAN ENTOMOLOGIST. 



terminal dark shade is outwardly rounded along its inner margin, and this 

 is. widely and everywhere nearly equi-distant from the external transverse 

 line : at the internal angle there is a slight projection corresponding with 

 the inward inferior inflection of the external line. The orbicular spot is 

 reduced and absorbed above by the dark eostal region, as is the reniform; 

 the latter is small, constricted, with a dark annulus, and very narrow pale 

 centre : both sp-ats concolorous with the dark costal region. There is a 

 short, dark, inner transverse line. The only other, the external, runs 

 slightly inwardly below eosta, then outwardly over the m. uervules, where 

 it is slightly interspaceally dentate ; thus, in its upper half ir is sinuate or 

 somewhat S-shaped. At 4th m. nervule, it runs, as usual, inward]}', thence 

 transversely, to internal margin. The fringes are dark, concolorous with 

 the terminal shade. A single line crosses the secondaries, projects over 

 the disc, and corresponds to the external line of the primaries. A distinct 

 discal dot. Apical angle shaded with plumbeous ; fringes, pale. Be- 

 neath, 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. 

 Exp., 30 m. m. August. Type in Mus. Peabody Academy of Science, 

 Salem, Mass. Nearly as large as B. flavidalis Guenee, and very con- 

 spicuous by the dark shades of anterior wings. 



Botys anticostalis Grotc. ^ . Bright yellow, with deeper 



ochreous tinges. This species has the markings and appearance of 

 Botys pliimbkostaUs. Costa of primaries broadly plumbeous, but shading 

 to yellowish towards the tips. Ordinary spots larger, annulate, freer from 

 the C3stal shade ; their centers are whitish iridescent ; the $ has no 

 orbicular, in its place the tegument is somewhat pellucid and impressed. 

 The two transverse lines are fainter 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 3rd m. ner- 

 vule, appearing as a spot at internal angle. Secondaries with a distinct 

 discal spot and single transverse line. Apices with the commencement of
