first segment well developed and inflated, open beneath. The wings 

 are opaque in this geuus and the species are soft brown and yellowish 

 in color. 



Horama diffissa. n. sp. 



Palpi, yellow; second joint clothed with mixed white and yellow 

 scales. The narrow epicranium is covered with dark brownish scales 

 which, when magnified, show a purple gloss. This scale patch is fring- 

 ed anteriorly by a few pale yellowish scales, which depend over the cly- 

 peus below the anteunal insertion. Ocelli, rather prominent, of a clear 

 yellow glassy color when viewed enlarged. Clypeus, in all my speci- 

 mens, deprived of scales, the dark brownish tegument being naked. 

 Antennae, ochreous, stained with brownish-black beyond their middle, 

 at their point of distension ; tips, dusky. The prominent "collar" is 

 pale yellow. Thorax and tegulae, covered with dusky brown scales. 

 Basal, or first abdominal, segment much distended, above covered with 

 white, short, close scales, which are interrupted centrally on the 

 " pouches" by clear yellow scale patches. Second and third segments 

 very dark brown abuve, with a dorsal yellow maculation on their ante- 

 rior margin aud larger yellow spots laterally. Terminal segments paler 

 brown. Beueath are two lateral yellow spots at the base of the second 

 and hind pair of legs. Rasal abdominal segments whitish beneath. 

 Legs, dark brown ; coxa?, yellow ; tarsi, dusky ochreous. 



Anterior wings of a rich soft brown color, immaculate, with a faint 

 yellowish or brighter tinge which, on the under surface, suffuses the 

 wings at base and along internal margin. Posterior wings, largely 

 bright ochreous yellow, with a dark-brown apical patch, below this lat- 

 ter the dark-brown scales form an incomplete border along the extern- 

 al margin. Under surface of secondaries, resembling upper surface. 



Two male and one female specimens, the latter with paler yellow se- 

 condaries, which want the brighter tint of the % on their upper sur- 

 faces. Exp., % and $ , 1.40 to 1.60 inch. Length of body, % , 0.50 

 inch.

Number 186. Poei/'s MS. Catalogue. 



This species may be at once distinguished from H. Pretus, Iliibn., 

 by its largely ochreous yellow secondaries and narrower wings. The 

 female specimen is probably faded.
