Argyrolepia ? Stephens. 



Fore wings with the costa regularly arched ; tip obtusely produced ; hind 

 margin oblique and slightly concave beneath the tip; cilia of the inner angle 

 produced. The disk ample, with the discal vein obliquely inclined ; apical vein 

 simple ; medio-posterior scarcely remote from the penultimate branch. Hind 

 wings with the subcostal vein forked in the apical third, with the discal vein 

 oblique but curved at its origin, midway between the base of the wing and the 

 fork of the subcostal ; the disco-central on an oblique stalk, further from the 

 medio-superior than the central is from the latter. 



Head smooth. Ocelli very small, scarcely perceptible. Antenna? setaceous, 

 pubescent. Palpi exceeding the face at least two thirds their length, porrected, 

 rather slender; basal joint curved, and equal to the face; middle joint slightly 

 hairy toward the tip; apical joint minute, ovate. Tongue as long as the labial 

 palpi. 



A.? lepidan a. Palpi pale ochreous white. Head ochreous. Fore wings 

 ochreous, somewhat silvery white at the base, with a broad, reddish, fawn- 

 colored central fascia parallel with the hinder margin, varied somewhat with dark 

 brown on the inner margin. This is edged externally by a somewhat silvery 

 ochreous line, which is furcate above the inner margin, enclosing an ochreous 

 spot. Apical portion of the wing reddish fawn-color, with a few black atoms 

 in the middle of the wing. Hind wings dark fuscous. 



C(ELOSTATHMA. 



Fore wings with the costa at the base arched, and thence slightly to the tip ; 

 apex acute, hind margin slightly concave. The disk is placed in the middle of 

 the wing, with the subcostal and median veins arched, rounded behind, and 

 extending scarcely more than one half the length of fore wings. The subcostal 

 vein has two marginal nervules from the disk, and the apical branch gives rise to 

 another near its origin, exterior to thu cell, and becomes furcate behind the tip. Hind 

 wings not broader than the fore wings ; costal and subcostal veins distinct, 

 with the latter furcate rather remote from the discal vein, which is curved, and 

 gives rise to a medio-discal nervule, almost in contact with the medio-superior 

 at its origin. 



Head smooth. With ocelli. Face with a slight horizontal tuft, and smooth 

 beneath it. Antennae plumose in the tf, pubescent in 9- Palpi exceed the face 

 by one half their length, arching to the middle of the face, thence porrected 

 and tapering to the apical joint ; middle joint with rather long scales from the 

 middle to the lip above, and on the entire undersurface ; from its clothing, broad 

 in the middle, and almost trapezoidal ; apical joint smooth, distinct and short ; 

 about as long as the basal. Tongue as long as the Dalpi in the tf ; nearly obso- 

 lete in the 9 (?) 



C. discopunctan a. Yellowish or luteous yellow. Fore wings with two 

 more or less distinct brown or reddish brown lines from the costa, inclined 

 towards the inner angle ; one nearly central and often shaded exteriorly, the 

 other near the hind margin. Costa with four blackish brown dots near the 

 tip, and a minute black point on the disk. Hind wings pale yellowish. The 

 female is usually darker colored than the male. 



Smicrotes. 

 Fore wings regularly arcuated from the base to the tip ; tip scarcely acute, 

 hind margin obliquely rounded; inner margin rounded. The disk is long and 

 narrow, and extends to the apical third of the wing; discal vein oblique. The 

 wing structure of fore wings as usual; medio-posterior remote from the penul- 

 timate branch; cilia of the inner angle somewhat produced. In the hind 

 wings the costa is emarginate or excavated a little exterior to the middle, and 

 along the hind margin ; not broader than the fore wings. The costal and sub-
