the wing. The chalky-white lines, which 

 define the outer margin of tlie spot are also 

 continued upon tlie secondaries, as are the 

 marginal cloudings. On the under side, 

 both wings are obscure fuscous with the 

 costa of the primaries near the apex a trifle 

 paler and marked with a few obscure wliitish 

 dots. There are faint suggestions on both 

 wings of transverse limbal lines. Expanse,

84. M. flavicostata, .sp. no\ . J. The 

 front deep black. The collar black witli its 

 inner margin bright vellow. Patagia and 

 upper side of thorax and abdomen blackish- 

 brown. Under side of the bod}' paler, 

 inclining to whitish. The first pair of legs 

 with the tibiae brown; the last two pairs 

 whitish. The primaries on the upper side 

 are very dark brown, inclining to blackish, 

 especially at the base. The costa is bor- 

 dered from the base almost to the apex by a 

 uniform narrow border of pale yellow, upon 

 which there is a faint suggestion of the 

 presence of an obscure transverse inedian 

 and transverse discal dark line, which are 

 scarcely distinguishable upon the dark 

 ground of the wing. The secondaries are 

 uniformly dai'k blackish-brown. On the 

 under side, both wings are obscure fuscous 

 with the costa of the primaries indistinctly 

 margined with pale ochraceous. Expanse, 

 24 mm. 



85. M. lithina,if. nov. J. Front fuscous. 

 Collar pale wood-brown. Patagia, thorax, 

 and metathoracic end of abdomen whitish 

 on the upper side. The upper side of the 

 latter portion of the abdomen is chocolate- 

 brown. The lower side of the thorax and 

 abdomen wiiitish. Legs concolorous. The 

 primaries and secondaries on the upper side 

 are prevalently brown. Along the costa of 

 the primaries is a broad whitish longitudinal 

 band, which is continued across the base of 



the secondaries. This band covers the 

 greater portion of the cell at the extremity 

 of whicli is a minute reniform spot. In the 

 middle of the cell are a few small obscure 

 olivaceous spots. The costa along the outer 

 border is faintly laved with pale olivaceous. 

 Just below the broad light colored band, 

 which borders the costa, located on the 

 outer margin, is a semi-circular whitisli spot 

 interrupted by some minute darker spots. 

 The wing is crossed by a very fine light 

 discal transverse line, which runs from near 

 the middle of the inner margin toward the 

 costa as far as the edge of the white band, 

 where it is sharply retracted, and terminates 

 upon the middle of the costa. This line is 

 continued upon the secondaries as a trans- 

 verse median line. On the lower side, both 

 wings are obscure pale fuscous ; both have a 

 pale discal dot at the end of the cell.

S6. M. discifascia, sp. nov. $. Front 

 and collar pale chocolate-brown. Patagia, 

 thorax, and metathoracic end of the abdomen 

 chalky-white. The posterior portion of the 

 abdomen on the upper side chocolate-brown. 

 The lower side of the thorax and abdomen 

 are very pale chocolate-brown. The legs 

 are concolorous. The costal tract of the 

 primaries is marked by a broad chalky-white 

 longitudinal band, extending from just before 

 the apex to the inner margin, covering about 

 one-third of its length from the base and 

 continued across the base of the secondaries. 

 This band is succeeded outwardly by a broad 

 band of pale chocolate running from the 

 middle of the inner margin toward the apex, 

 and terminating in a point near the origin 

 of the median nervules. This band is con- 

 tinued across the secondaries, covering the 

 outer end of the cell and is defined on the 

 secondaries by a fine sub-basal and somewhat 

 irregularly curved transverse median line. 

 This band is succeeded in the primaries by a 

 paler area, which is likewise continued across
