median interspaces behind the band. At the tip is a large whitish roseate 

 patch, three contiguous black spots at the end of post apical interspace, with 

 a wavy black, submarginal line. Hind margin luteo-testaceous. Hind wings, 

 trigonate vitreous patch somewhat larger than in fore wings, with a trans- 

 nervular band similar to fore wings, continued around the costa to the base 

 of the wing and the medio-posterior interspace and those adjoining it, 

 powdered with whitish roseate behind the band. Hind margin luteo-testa- 

 ceous with a row oflblack spots and a dark brown line.

H. interrupto-marginata. Bombix interrupto-marginata, De 

 Beauvois Ins. Afriq. et Amer. p. 265, pi. 24, f. 5, 6. Head and labial palpi 

 pale orange yellow, the latter with black tips. Thorax pale yellow, with 

 a broad black stripe on the disk. Abdomen orange yellow, with a dorsal 

 black stripe. Fore wings pale yellow, with a black streak along the costa 

 not reaching the tip of the wing, a broad streak of the same hue along 

 the inner margin, sending from the inner angle toward the hind end of the 

 disk, a hooked demi-band ; hind margin black in the middle. Hind wings 

 pale orange-yellow, with a black spot near the inner angle and a larger 

 one in the middle of the medio-posterior interspace and nervule. Legs 

 pale orange-yellow.

 Anorthosia. 



Anterior wings rather narrow, and somewhat lanceolate. The subcostal 

 nervure is nearly straight and gives off from the disk, which is unclosed, 

 three marginal nervules and becomes bifid before the tip. The discal ner- 

 vule is independent. The median is four-branched, its last nervule is bifid, 

 and arises opposite the middle of the origins of the 2d and 3d subcosto 

 marginals. The submedian is bifid at its base. 



Hind wings somewhat emarginate behind the tip on the external mar- 

 gin, and rather deeply emarginate beneath the tip. Disk unclosed. Sub- 

 costal nervure bifid from the end of the disk. This discal nervule is trans- 

 ferred to the median side, and the median nervure is three-branched. 



Head and face smooth; vertex elongated, with long loose scales over- 

 lapping in the middle. Forehead rounded. Ocelli very small. Eyes small, 

 round and salient. Antenna? about one third less long than the anterior 

 wings, basal joint long and slender, the stalk slightly denticulated beneath. 

 Maxillary palpi extremely small. Labial palpi, smooth, long and porrected, 

 their development being almost entirely in the second joint, ivhich is sup- 

 plied above with long hairs capable of being erected, although usually decumb- 

 ent, and with the third joint short, very slender, smooth and pointed, arising 

 nearly erectly at the apical third of the second, and is likewise capable of being 

 erected or depressed. Tongue scaled at the base and about as long as the 

 labial palpi. 



A. p unc ti pen n e 11 a. Labial palpi and head rather dark ochreous, 

 the former dark brownish externally. Antennae ochreous, annulated with 

 dark brown. Fore wings rather dark ochreous, sometimes dusted with dark 

 brownish, with three pairs of blackish brown dots along the fold, the first 

 near the base of the wing, the second rather above the middle and the third 

 near its end. One dot of each of the latter pairs, is in the fold, the other 

 above it obliquely. The costa at the base, and beyond the middle is touched 

 with blackish, with the hinder portion of the wing dotted and dusted with 

 dark brown, especially along the hinder margin. Cilia ochreous. Hind 

 wings shining, blackish gray, cilia the same. Abdomen blackish.
