numerous narrow transverse darker lines. 

 At the base, the wings are chalky-white with 

 a heavy dark brown area just beyond. The 

 upper half of the wing from the base of the 

 costa outwardly is chalky-white, save just be- 

 fore the apex, where this white area is inter- 

 rupted by a series of dark brown transverse 

 limbal markings, which are followed by 

 some minute submarginal dashes. The 

 fringes are pale brown, palest at the apex, 

 and uniformly checked with dark brown. 

 The secondaries above are pale fulvous. Un- 

 der side : Both wings below are pale fulvous 

 with the costa and middle area of the prim- 

 aries faintly clouded with fuliginous. Ex- 

 panse, 30 mm. 



123. /. diluta, sp. nov. $ . The body 

 and legs are uniformly pale cinereous. The 

 primaries on the upper side are chalky-white 

 clouded on the inner margin with pale brown 

 and traversed on the inner half by incom- 

 plete, sub-basal, median, limbal, and sub- 

 marginal pale brown lines, the outer lines 

 being produced farther in the direction of the 

 costa than the sub-basal lines. The fringes 

 of the primaries are dark brown checked with 

 pale brown. The secondaries are uniformly 

 pale shining white. On the under side both 

 wings are whitish, the primaries having a 

 very dark brown ray extending along the 

 costa from the base to the apex, the costal 

 edge being white. Expanse, 20 mm. 



124. I.jffava, sp. nov. $. The body and 

 legs are pale yellowish-cinereous. Upon the 

 dorsal line of the primaries is a series of 

 three or four minute dark brown tufts of 

 scales. The primaries are pale luteous- 

 brown clouded on the middle and outer mar 

 gin of the wing with obscure darker brown 

 markings. The secondaries are pale grayish- 

 luteous with some obscure dark brown mark- 

 ings at the anal angle. The under side of 

 both wings is very pale yellowish-gray, the 

 darker bands and spots of the upper side re- 

 appearing more or less obscurely. There is 

 considerable variation among the specimens. 

 Expanse, 23 mm. 



125. /. pallida, sp. nov. $. Body ob- 

 scure grayish. Primaries whitish on the 

 upper side with the costa clouded with green- 

 ish-gray. There are a number of obscure 

 transverse dark cloudings on the costa, and 

 minute blackish dots scattered over the basal 

 half. There is an obscure discal dot at the 

 end of the cell. Beyond this, there are two 

 very narrow angulated and parallel blackish 

 lines, between which there is a paler area. 

 On the margin opposite the end of the cell, 

 there is a comparatively large brown spot. 

 The margin is accentuated by a series of 

 brown dots on the interspaces. The fringes 

 are very pale ashen, checked with paler gray. 

 The secondaries are whitish, slightly clouded 

 with gray at the outer angle. On the under 

 side, both wings are whitish. The costal 

 area of the primaries is clouded with dark 

 gray and the secondaries have on their costa 

 near the outer angle two parallel and incom- 

 plete transverse lines. Expanse, 22 mm. 



126. /. fusca, sp. nov. $ . Body wood- 

 brown, primaries and secondaries of the 

 same color, the outer margins of both wings 

 clouded with darker brown. The primaries 

 are marked on the cell by a number of min- 

 ute blackish dots. The fringes of the prim- 

 aries are dark brown, of the secondaries, pale 

 cinereous. On the under side, both wings 

 are paler, both have a conspicuous discal dot 

 at the end of the cell. The primaries have a 

 submarginal series of conspicuous dark 

 brown dots running in a straight line from 

 below the apex near the outer angle. The 

 secondaries have two or three conspicuous 

 submarginal brown dots near the outer angle 

 and a conspicuous brown patch of scales at 

 the anal angle. Expanse, 26 mm.

127. O. costiplaga, sp. nov. $. Front, 

 collar, and patagia whitish; thorax and ab- 

 domen pale cinereous above; and on the dor- 

 sal line of the abdomen there is a narrow 

 raised crest of dark gray hairs; the pectus is 

 dark brown; the lower side of the abdomen,
