ACRONYCTINAE 



Trachea rubiginosa Wlk. 



Sir Geo. Hampson informs us that this species, listed by us in 

 the genus Oligia, is in all probability a synonym of Trachea binotata 

 Wlk., being another of those cases in which Walker described the 

 same specimen twice under different names. Rubiginosa was described 

 from a S from Vancouver Is. presented by Dr. Lyall (Cat. Lep. P.. 

 M. XXXII, 674) and binotata a few pages previously (1. c. p. 663) 

 from a specimen from the same source and locality so that there is 

 every reason to believe that Hampson is correct, especially as nothing 

 in the description contradicts this association. 



Trachea monica sp. nov. (PI. XV, Fig. 9). 



Very similar to susqucsa Sm. (Fig. 8) of which it may be possibly a race; 

 the general ground color of the primaries is much deeper with less of the 

 light brown shades; the pale areas, on the contrary, beyond the reniform and 

 claviform are paler, almost whitish and the veins 3, 4, 6 and 7 are better out- 

 lined terminally with white; the maculation is similar, but more indistinct; 

 the general squammation of the wing is rougher; secondaries rather heavily 

 and evenly sprinkled with smoky over a white ground; on the underside the 

 discal spot which is quite prominent in susquesa is reduced to the merest 

 dot and there is no postmedian line ; the excavation of the outer margin at vein 

 5 appears also to be rather smaller; the wing expanse (34 mm.) is distinctly 

 larger.

Trachea serrula sp. nov. (PI. XVI, Fig. 7). 



S antennae distinctly serrate and fasciculate; head and thorax dark 

 gray, peppered with white; primaries similar in color with slight pale ochreous 

 shades beyond reniform and claviform and a rather indistinct maculation with 

 the exception of a black basal streak and a large claviform, outlined in black 

 and extending across the whole median space; t. a. line scarcely traceable, in 

 general slightly oblique and irregular; t. p. line obscure, bent outward below 

 costa to just beyond reniform and then inwardly oblique, passing very close 

 to lower end of reniform, orbicular dark, oval, partially outlined with white; 

 reniform figure-of-eight-shaped, outlined, especially in lower portion, with 

 black and followed by a palish shade occupying the betid of the t. p. line; s. t. 

 line close to outer margin, obscure, best marked by white dentate streaks on 

 veins 3 and 4 and 6 and 7; terminal space somewhat darker than subterminal 

 one; fringes dark, spotted with ochreous at end of veins; secondaries strongly 

 excavated at vein 5, whitish in $ with veins and outer border sprinkled with 

 smoky, in 9 largely smoky. Beneath pale, more or less sprinkled with smoky, 

 especially primaries, with small discal dot on each wing. Expanse 30 mm.
