(19.) Zotheca tranquilla, Grote. 



S . — The color is a dusty pale brownish red, and the fore wings have a pow- 

 dery look. The t. a. line is obsolete, as is the orbicular spot. The reniform 

 is hardly to be made out, narrow and concolorous. The t. p. line is distinct, 

 darker than the wing, much outwardly projected on vein 6, single, followed 

 by a faintly paler shade, running inwardly obliquely and a little flexed to 

 internal margin ; s. t. line wanting ; fringes darker than the wing. The me- 

 dian space is darker clouded centrally. Hind wings whitish faintly powdered 

 with reddish outwardly, and with pale reddish fringes. The costal region of 

 primaries, above the t. p. line before the apex, is darker shaded, and here the 

 costal edge shows paler anteapical dots. Beneath both wings are whitish 

 powdered with reddish along costal regions and outwardly, and showing the 

 commencements of a common outer transverse line ; on the primaries the 

 narrow reniform is reflected. Body concolorous, with wings; the woolly 

 thorax shows an underlying yellowish tint.

 No. 160). 



(20.) Scopelosoma Graeflana, Grote. 



<* . — The eyes are naked ; the body flattened ; the squamation rough as in 

 this genus, not smooth as in Glaea. The wings are elongate, the terminal line 

 distinctly waved on the primaries, so that the fringes are uneven. The fore 

 wings are narrow and long, with parallel margins and sharp apices. The orna- 

 mentation is different from either Walkeri or vinulenta, and the colors are as 

 in some species of Xanthia, but I cannot separate this and the following spe- 

 cies generically from either of the other species here referred to Scopelosoma. 

 Yellow, powdered with deep orange. The fore wings are crossed by four 

 nearly equidistant and straight, dark orange brown, even and distinct lines. 

 The first of these is the basal half-line, angulated on the median vein. The 

 second is the t. a. line, nearly straight. The third is the median shade, unu- 

 sually distinct and continued, margining inwardly the reniform. The fourth 

 is the t. p. line shortly projected outwardly at costa, narrow, darker than the 

 j-est, even and a little inwardly oblique. The ordinary spots are concolorous, 

 with complete orange annuli, the orbicular moderate and spherical, the reni- 

 form large, with a faint inferior stain, outwardly excavate. The subterminal 

 line is irregular and faint. The nervules are marked with dark scales. The 

 hind wings are light yellowish with an orange cast which leaves the costal 

 region free. A faint median line reflected from beneath ; fringes pale. Be- 

 neath pale yellowish with a distinct continued orange line, a little irregular 

 on hind wings which show a discal dot. Costa of fore wings touched with 

 dusky towards the tips. Terminal irregular line accented, dark and fine on 

 both wings. Body parts beneath pale yellowish ; above the thorax and head 

 with the fore tibiae are dusky orange.
