193. M. nigribasis, sp. nov. $. The 

 lower sides of the palpi are pale fulvous-gray. 

 The upper side of the palpi, the front, collar, 

 patagia, and upper side of the thorax are 

 blackish brown. The upper side of the 

 abdomen is fuscous, darkest on the dorsal 

 line. The under sides of the thorax and 

 abdomen and the legs are pale gray. The 

 primaries on the upper side are pale wood- 

 brown with a pinkish reflection shading into 

 darker brown toward the apex and the outer 

 margin. The patch of raised scales on the 

 inner margin at the base is dark blackish- 

 brown like the costa. The primaries are 

 traversed from the costa just before the apex 

 to the middle of the inner margin by a 

 narrow dark brown straight line, bordered 

 externally by a paler parallel line. The 

 secondaries are fuscous, darkest, on the outer 

 margins. On the under side the primaries 

 are pale fuscous, with the costa and the 

 middle area darker. The outer margin of 

 this darker median area is sharply defined as 

 a curved line, which is followed by a paler 

 shade. The outer margin is darker, and at 

 the end of the cell there is an obscure discal 

 mark. The secondaries on the lower side are 

 paler than the primaries and are traversed by 

 an obscure curved transverse limbal line. 

 The margins are obscurely bordered with 

 darker fuscous. Expanse, 30 mm. 



194. M. albibasis, sp. nov. $ . Lower 

 side of palpi pale ferruginous. Front, collar, 

 patagia, upper side of thorax, and abdomen 

 fawn; lower side of thorax and abdomen and 

 legs very pale cinereous. The primaries on 

 the upper side are pale wood-brown, or fawn, 

 traversed from the costa before the apex to 

 the inner margin two-thirds of the distance 

 from the base by a narrow irregularly, and 

 slightly curved darker line, bordered exter- 

 nally by very narrow paler lines. The raised 

 patch of scales on the inner margin at the 

 base is whitish defined on its upper margin 

 bv a darker shade which extends outwardly 

 alon«- the inner margin to the termination of 



the narrow- transverse limbal line. There is 

 an obscure round dark spot in the middle of 

 the cell, an obscure linear mark of the same 

 color at its end. The secondaries are uniform lv 

 pale fuscous. On the under side, both 

 wings are pale fuscous. The primaries have 

 the middle area and the costa clouded with 

 darker brown, the outer margin of this darker 

 area being well defined against the paler 

 marginal area. The fringes of the primaries 

 are dark brown. The secondaries are tra- 

 versed from the costa beyond its middle by a 

 curved incomplete transverse limbal band of 

 dark brown. The fringes of the secondaries 

 are concolorous. Expanse, 25 mm. 



195. M. obliterata, sp. nov. $ . Head 

 whitish. Collar, patagia, and upper side of 

 thorax dark cinereous. Upper side of 

 abdomen pale brown ; lower side of thorax 

 and abdomen with legs whitish. The 

 primaries are pale ferruginous. At the end 

 of the cell., there are two small spots of whitish 

 raised scales margined with blackish. Beyond 

 the cell there is a narrow and very obscure" 

 transverse limbal line, regularly curved out- 

 wardly, running from the costa before the 

 apex to the inner margin two-thirds of the 

 distancefrom the base. The patch of raised 

 scales on the inner margin at the base is 

 cinereous, defined on its upper side by a 

 brownish spot. The secondaries are uniform h 

 pale creamy, tinged on the outer margin with 

 fuscous. On the under side both wings are 

 shining creamy with the fringes of the prim- 

 aries dark brown, and a faint brownish shade 

 on the upper margin of the cell below the 

 costa. Expanse, 30 mm. 



Dixotodonta, gen. nov. 



Allied to Dasunaga, Moore. The palpi are 

 short. ascCnding, compressed, scarcely reach- 

 ing beyond the vertex; the third joint is verj 

 short, hemispherical ; the second joint rela- 

 tivelv very long. The antennae in the male 

 are simple, slightly ciliated on the lower side
