llyppa iii4li*«tiiu*fa n. sp. (PI. iv, fig. 4)— Tliis species can he best de- 

 scrilxMl hy conipaiiiiir it with the common xylinoides, which it reseint)les in the 

 general style of the markings and in color. In the new species the ground color 

 is paler throughout, the gray much more even. The t. a. line is almost obsolete, 

 and marked only as a curved line though the costal region. The short, black, 

 basal streak in xylinoides is here replaced by a broad streak, which is continuous 

 through the median space to the t. p. line. The latter is more even than in its 

 ally, and is much less distinct. The s. t. line lacks all the powdery appearance, 

 and has a mere indication of the prominent W-mark of the usual form. The 

 ordinary spots are scarcely defined, but as much as can be mtide out, resembles 

 those of xyUnoules. Finally, the tufting of the dorsum of the abdomen is less 

 prominent in the new species. Expands as in xylinoides. 



Hab. — Mount Hood, Graef. 



The single male specimen has been considerable of a i)uzzle to me. 

 I have tried to make it out a variety of the common species, and 

 have compared it with numerous western specimens, without at any 

 time finding one like it, or near enough to it, to make it of use as an 

 intergrade. Yet I will not he at all surj)rised if in the future this 

 proves a local form, the name then representing a very distinct va- 

 riety. I have held the specimen nearly a year hoping to get othei's 

 like it. 



Oncociieillis piitloratsi n. sp. (PI. ii, fig. 8)— Head, thorax and primaries 

 a dull, olivaceous powdery fuscous gray, with an admixture of black and white 

 scales. Head and thorax innnaculate. The primaries have the normal mark- 

 ings traceable, but all indefinite, interrupted and pulveruleiit. The half line is 

 blackish, apparently single. T. a. line obsoletely geminate, the outer line only 

 distinct, blackish, outwardly oblique in general cour.se, rather evenly outcurved 

 between the veins. T. p. line obsoletely geminate, the outer part of line indefi- 

 nite, the inner outwardly denticulate on the veins. A white shade follows the 

 t. p. line, darkening rapidly until, at the s. t. line, it forms an irregular blackish 

 shade, which, by its greater or less contrast with the terminal space, defines the 

 s. t. line. A blackish, interrupted terminal line. A dull yellowish line at base 

 of fringes, which have also an interline of the same color. There is an almost 

 upright, broad, diffuse dark shade through the median space. The claviform is 

 vague, concolorous, defined only by a few darker scales. Orbicular round, or 

 nearly so, slightly paler, with concolorous centre, and no very obvious defining 

 line, lieniform yet more vaguely defined, slightly paler, centred with concolor- 

 ous, broad, upright. Secondaries black, with a broad white median band, at the 

 margin of which the black discal spot is partly visible, and through which the 

 veins are marked with blackish. Fringes white, with a fuscous interline. Be- 

 neath, white with a broad black outer maigin, a discal spot and a more or less 

 dense black powdering at the base. Expands 28-29 mm. ; 1.12-1.16 inches.

Two specimens, male and female are before me, and I understand 

 that Mr. Bean has others. The species belongs to i\\e fasciatus group,
