222 JOHN B. SMITH. 



Head brown, vertex paler. Thorax pale fawn, with the dorsum broadly deep 

 brown, widening to the base — in fact leaving the patagise only pale; the latter 

 sometimes with a rosy flush. Abdomen bright fawn color, immaculate. Prima- 

 ries above dun or fawn of various shades. Base to the augulated line paler than 

 the rest of the wing; median space below the cell darker, richer brown than 

 elsewhere; beyond the outer transverse lines the wing is again darker with jialor 

 powderings toward apex and anal angle : an indistinct transverse line banded by 

 a diffuse dusky shade each side, through the basal space. A very sharply defined 

 outwardly oblique shade line from costa at basal third — narrow through the cell, 

 broadening out below — to below vein two; there acutely angled and inwardly 

 oblique, and somewhat convex to internal margin at basal third. This line is 

 variable in the amount and acuteness of its angulation ; sometimes the angle is 

 rounded, and drawn out very acutely so as almost to meet the outer transverse 

 line. A pale, somewhat yellowish, lunate, discal spot; the median vein broadly 

 pale marked through the median space. A somewhat indefiTiite oblique trans- 

 verse pale line at outer third, beyond which is another parallel to it, preceded by 

 a dark shade. A very indistinct subterminal pale shade. An angulated pale 

 mark before the apex, outwardly ditl'use along costa. Anal angle pale powdered. 

 Secondaries rosy at base, with broad pale fawn margins; a large, round, ocellate 

 spot ; black ringed, blue centred and with black pupil, connected with the anal 

 angle by a short black dash. Beneath, rosy at base, pale fawn outwardly, the 

 maculation of upper side reproduced. Secondaries pale fawn, with a discal spot 

 and two parallel pale median lines. Exjiands 2.50 — 3.25 inches; 6.3 — 81 mm.

This species seems variable only in the depth of ground color, and 

 the paler form Mr. Edwards has named pcdlkhdus. The vai-iety 

 intergrades fully and very gradually with the type form throughout 

 its entire range. The species does not seem common. The side piece 

 of the male is rather narrow, the tip obtusely rounded. From the 

 upper side near the tip arises a spatulate corneous process, somewhat 

 dilated and rounded at the tip. The projection from the lower mar- 

 gin is nearer the middle, and is very nuich stouter and longer, .some- 

 what beak-like, acute at tip. Mr. Butler speaks of " A female ex- 

 am})le of a species from Vancouver's Island is also in the collection ; 

 although rather a large insect, it approaches very close to S. opldhal- 

 micus 9 , as figured by Strecker, but has the primaries of a nuich 

 browner tint, as in S. ocellatus, and less excavated below external 

 angle ; the central band forms a large, oblong patch on inner mar- 

 gin, and the whitish submarginal streak is less distinct. The second- 

 aries are bright rose color, excepting a narrow buff outer border and 

 a diffuse whitish patch at anal angle ; the ocellus is larger. I pro- 

 pose to call it S. vancouverensis." 



Mr. Edwards has described the early stages of this species.
