Sericoris mutabilana, n. s. — Fore wings reddish-brown, yellowish or pale- 

 ochreous, with reddish -brown or testaceous-brown markings. The basal patch 

 is angulated and at the base of the wing, shows the general hue. The central 

 fascia is well marked and on its outer edge in the middle of the wing is a 

 whitish discal dot. There is a subterminal fascia extending from the costa 

 near the tip to the hinder margin above the anal angle. On the basal patch 

 and central fascia are short black striae. On each side of the central fascia are 

 spaces, or bands of the general hue, each having a dark brownish line running 

 its middle. The costa is spotted with blackish and geminated with yellowish 

 or pale ochreous. 



In the reddish-brown specimen or variety, the pale interspaces are 

 ochreous on the costa and beneath it, are discolored with reddish. 



It is scarcely possible, with the specimens before me to distinguish 

 the species from the variety, and f therefore forbear to make a conjec- 

 ture. The description has been written so as to include all the varia- 

 tions of hue.

Sericoris instrutana, n. s. 



This specimen may be a mere variation of fasciatana. The orna- 

 mentation of the wings is very similar, as well as the color, but the size 

 of the specimen is much less. 



The whitish spaces on each side of the central fascia is more tinted 

 with ochreous than in fasciatana. The outer margin of the basal patch 

 shows two indentations and a central tooth or projection, while in fas- 

 ciatana the outer margin is nearly straight or slightly curved. The 

 central fascia is very narrow on the costa, dilating in the middle of the 

 wing, its exterior margin bulging outwards and is somewhat interrupted 

 near the inner margin of the wing; in fasciatana it is broad and dif- 

 fuse on the costa. In instrutana the markings of the wings are pure 

 dark brown, in fasciatana they are testaceous brown.

Sericoris fcedana, n. s. 



This specimen, although of much smaller size, recalls permundana; 

 but the pale spaces on each side of the central fascia are much broader 

 in fcedana than in permundana. 



Fore wings luteous with brown markings. The basal patch is deeply 

 divided and forms three patches, the smallest of which is near the costa 

 and is separated from the other parts. The central fascia is brown and 

 is likewise divided into three parts, each of which is narrowly mar- 

 gined with dull bluish edging. The oblique streak from the hinder 

 margin is brown and ed^ed on both sides with dull-bluish.
