24 GROTE AND ROBINSON. 



the wing, and are, with the basal portion, slightly dusted with brighter 

 scales. An inner, waved, transverse line. Two ordinary diseal spots. 

 An exterior, finely dentated. transverse line, which is prominently and 

 roundedly outwardly projected opposite the disc. A faintly marked 

 and straighter sub-terminal sh;>de line, difficult to discern, but quite 

 distinctly marked in cinereous on the under surface. Fringes, conco- 

 lorous, or a little paler than the wings. The external edge of both 

 secondaries and primaries is narrowly lined with darker ochrey-yellow ; 

 this is quite apparent on the under surface owing to the pallor of the 

 wings, where the line appears broken interspaceally. 



Secondaries, resembling primaries. As usual, the ba.se, costal and 

 internal margins are diffusedly paler and whitish, while the darker and 

 yellow color is expressed centrally along external margin, fading me- 

 dially over the centre of the wing. Outside of the disc the wing is 

 crossed by two sub-parallel .shade lines, of which the inner corres- 

 ponds to the exterior transverse line of the primaries; the outer, to 

 the sub-median shade line. Fringes a little paler than the wing, be- 

 coming whitish towards anal angle. 



Beneath, both wings are glistening, obscure whitish, with a slight 

 opaline reflection. The markings of the upper surface are here more 

 distinctly reproduced in pale cinereous. The costa of primaries and 

 external margin of both wings are shaded with obscure ochrey yel- 

 low.

Ilohitat. — Atlantic District. (Penna. !) 



Differs from Botys citrina, noh. by its larger size, paler color, indis- 

 tinct ornamentation and by the presence of sub-median lines of both 

 wings. 



Botys insularis, n. sp. (Plate 2, fig. 24, % ). 



%. Size rather large. Cinereous. Head, thorax and abdomen, of 

 an even dull cinereous. Beneath, the short palpi, legs and abdomen 

 are whitish cinereous, glistening. Legs, long, armature well deve- 

 loped. 



Wings, full. Primaries with the tips a little produced, entirely and 

 evenly cinereous, with obsolete ornamentation, but the usual exterior 

 transverse line is faintly visible and greatly and roundedly arcuate at 

 the middle. Fringes, a little paler than the wing, very silky. Secon- 

 daries, a little paler than primaries, evenly cinereous, but becoming a 

 little paler basally and along costal and internal margins. As on pri- 

 maries, a single transverse, irregular, extra diseal shade line is barely
