its course may be traced by a series of imperfect streaks, nearly 

 to the posterior margin, thence about the middle of the wing it 

 forms a very acute angle to the centre of the internal margin and 

 is slightly dentate outwardly. There is a conspicuous discal mark, 

 some streaks near the apex of the costa, and others near the in- 

 ternal angle, blackish-brown, fringe fawn color. Secondaries, sor- 

 did white, with a blackish blotch on anal angle, and the fringes 

 and margin dusky. Beneath, the wings are sordid white, shading 

 into dusky on the costa, the primaries broadly so, and enclosing 

 some blackish streaks. Antennse fawn color. Thorax brownish 

 fawn color, mottled with darker shade, the collar brown-black. 

 Abdomen sordid white, shading into fawn-color at the base. 

 Legs fawn color, mottled with brownish.

 COSSUS MUCIDUS. n. sp. 



Size small. Primaries grayish-brown, mottled with darker 

 shades, the margins being broadly pale, and of a purer gray tint. 

 Reaching from the base to the cell on the costal half of the wing- 

 is a conspicuous whitish shade, the whole of the wing flecked 

 with greyish and brown atoms. Fringe alternately brown and 

 sordid white. Secondaries dusky white, mottled with brown. 

 Thorax and abdomen concolorous. Beneath, the primaries are 

 mottled with brown on a dusky ground, and the secondaries are 

 as on the upper side. Abdomen considerably longer than the 

 lower wings in both sexes. In the $ , there are indications of 

 brown rings at the junction of the segments.

 EUCH^TES PUDENS. n. sp. 



Closely allied to E. collaris, but considerably smaller. Clear 

 white, with the costa pale buff for about one-third of its length ; 

 the collar also buff, this color being by no means extended to the 

 thorax, as it is in E. collaris. Abdomen yellowish-white, with 

 the abdominal spots very small and indistinct, being reduced to 

 mere points. Fore legs only slightly stained with buff.

I have examined a large number of E. collaris, and compared 

 them with the present specimen. In all I find the costa yellow 

 almost to the apex, and the tegulae and upper half of the thorax 

 well marked with the same color, neither of which characters 

 obtains in the present form.
