upon the sides and the lower surface of the two anterior segments of the abdomen 

 there are conspicuous bhick spots; legs concolorous, the tarsi a trifle darker; ant.enna> 

 testaceous. The fore wing on the upper side is pale grayish fawn, becoming shghtly 

 darker towards the termen; two or three minute dark basal spots, succeeded by a 

 very fine outwardly curved subbasal line; the cell faintly clouded near its extremity 

 by darker brown, and with a miiiute, but very distinct black spot at its end; beyond 

 the cell a double postmedian line running obliquely from the costa two-thirds of its 

 length from the base to the inner margin at its middle; beyond this line near the 

 costa the wing becomes lighter in color, almost white; for a short distance this lighter 

 area being crossed by a very fine brown line, which runs from the costa as far as vein 

 6, where it terminates upon the subcostal line; the subcostal line is fine, dark brown, 

 and beginning at the apex curves inwardly at first and then, as it ajiproaches the 

 inner margin, Ijccomes almost parallel with the postmedian line; the space between 

 the subcostal line and the outer margin, near the extremities of veins 5 and 6 is marked 

 by two deep black spots, accentuated externally by lighter scales, which in turn are 

 succeeded by two fine sagittate marks; the costa near the apex is narrowly bordered 

 by white, the tips of the subcostal nervules indicated by minute black spots, the 

 fringes are dark below the apex, but become lighter near the tornus. The hind wing 

 on the uj)per side is pale creamy white, clouded on the outer margin opposite the end 

 of the cell and at the anal angle with dark scales; the fringes are uniformly whitish. 

 On the under side the ground-color of both wings is creamj' white. The fore wing on 

 the costa above the cell, and more broadly beyond the cell, is clouded with pale gray; 

 there is a faint trace of a discal spot at the end of the cell; a submarginal row of very 

 small, but distinct, dark spots, located on the veins, extends from the costa to the 

 inner margin at about three-fourths of the length of the wing from the base; beyond 

 this line in the region of veins 5-7 are a series of zigzag dark lines, and the fringes 

 near the apex are dark, becoming lighter toward the tornus. The hind wing is on its 

 costal or uijper half dusted with gray scales, and there are a few such scales near the 

 anal angle. At the end of the cell there is a minute transverse discal si)ot; beyond this, 

 running from the costa as far as vein 4, are two parallel outwardly angulated dark 

 lines; the submarginal series of small dark spots, which is conspicuous upon the fore 

 wing, is continued upon the hind wing as far as vein 2, but does not in the type 

 appear upon vein 1 ; the dark shades beyond the end of the cell of the upper side re- 

 appear upon the lower side, but are darker on the lower side. Expanse, 46 mm. 



The type, which is unique, was taken at Medje, August 1, 1910, 

 x\m\ lii in The American Museum of Natural Histoiy. 



The insect is strictl}- congeneric with the species which I described as 

 Ctenogyna (f ) vilis and Ctenogyna(f) ogcvensis (cf . Entomological News, IV, 

 1893, p. 343, PI. XV, figs. 12, 13). The type of the genus Ctenogyna 

 is the species named natalensis by Felder, which I do not have in my 

 collection but which I think I saw in London or at Tring and the hke- 

 ness of which to the insects before me I recognized at the time. The 

 generic reference is provisional, but possibly quite correct. It is, how- 

 ever, not wise to dogmatize in such matters.
