gray. The primaries are dark fuliginous with 

 the apex and the inner margin whitish. The 

 white apical area is interrupted by a conspic- 

 uous dark brown spot, having the form of a 

 compressed comma. The secondaries are 

 grayish with the costa and outer margins 

 lighter. On the under side, both wings are 

 whitish with the middle area of the primaries 

 from the cell toward the outer margin 

 clouded with dark gray. There is an obscure 

 discal dot at the end of the cell of the second- 

 aries. Expanse, 40 mm. 



128. O. hyloica, sp. nov. J. Front whit- 

 ish; collar brownish-gray, marked on the 

 median line in front by a raised tuft of dark 

 brown scales; patagia yellowish, tipped 

 with reddish-brown ; upper side of the thorax 

 and abdomen dark brown ; the tip of the ab- 

 domen whitish; the lower side of the abdo- 

 men and thorax and the legs are grayish- 

 white. The prevalent color of the primaries 

 is pale purplish brown, interrupted by a 

 wedge-shaped area of lighter color, extending 

 from about the middle of the cell to the apex, 

 and interrupted by a dark brown ocellus at 

 the end of the cell, some narrow lines of dark 

 brown beyond this ocellus, parallel to the 

 median nervules, and by a dark brown dash 

 on the costa before the apex. In addition to 

 these markings, there is a dark transverse 

 basal and a geminate transverse median line 

 beyond this darker marking. The second- 

 aries are white. On the under side, both 

 wings are whitish-gray with distinct Iunulate 

 discal markings at the end of the cell, those 

 of the primaries being most conspicuous. In 

 addition, the markings of the upper surface 

 of the primaries faintly reappear upon the 

 lower side. Expanse, 42 mm.

129. N. agrotoi'des, sp. nov. $. Front 

 fuscous; antennae and entire thorax and 

 abdomen, except the tip of the latter, which 

 is brown, luteous. Upper side: Primaries 



lilacine-brown, except at the outer angle, 

 which is pale ashen. The primaries are 

 crossed by numerous marks and striae as 

 follows : an irregularly curved sub-basal line, 

 luteous, defined inwardly very narrowly by 

 dark brown followed by a dark annulus on 

 the middle of the cell, and an obscure one at 

 the end of it; below the cell beyond the base 

 near the inner margin is a dark brown patch 

 of raised scales having the form of an oblong 

 parallelogram; there are obscure and very 

 narrow transverse limbal and transverse sub- 

 marginal lines with spots and striae upon the 

 costa. The secondaries are whitish shaded 

 with fuscous on the outer margin. Under 

 side: the wings are whitish, silky, with the 

 basal and median area of the primaries 

 clouded with fuscous. Expanse, 28 mm. 



130. N. nigristriata, sp. nov. J. Front, 

 body, and appendages whitish. Upper side: 

 Primaries chalky-white on the costal half 

 and on the inner half very pale luteous. 

 There is a white curved sub-basal line, and a 

 similar curved white line running from below 

 the apex on the outer margin to the inner 

 margin, two-thirds of the distance from the 

 base. Between these two lines there is a 

 broad blackish clouding below the end of the 

 cell, continued outwardly towards the outer 

 margin above the origin of the outer white 

 line. Above this clouding below the apex at 

 the outer margin is a narrow blackish ray. 

 There is a minute black annulus at the end 

 of the cell. The secondaries are pure white. 

 Under side : Both wings are white tinged with 

 creamy. Expanse, 25 mm. 



131. N. erudescens, sp. nov. J. Body 

 whitish with the pectus and legs tinged with 

 pink. Upper side : The primaries are bright 

 pink, except at the outer angle, where they 

 are suffused with creamy-white. There is a 

 poorly defined sub-basal line of darker pink 

 and an annulus of darker pink at the end of 

 the cell. The secondaries are creamy-white- 

 Under side: Both wings are creamy-white
