AND THEIR TRANSFORMATIONS. 37 



Species 7- — Harpalyce ttnangdlata ''. — (Plate LXIII., Fig. 26). — This is another species, which 

 measures about li inch in expanse, and is closely allied to the preceding, from which it is especially distinguished 

 by the acute angle formed at tlie middle of the outer margin of the central fascia of the fore wings ; in tlic 

 middle of this fascia is the ordinary black stignia-like spot, and the costa is marked towards the apex with a 

 square blackish spot, from whence e.xtends a grayish bar, followed by a regularly-waved white striga ; the hind Una^Le<^^ 

 wings have a central dot, and the base rather ashy, with the strigae somewhat more distinct. Found in woods '^'■^ 

 but rarely, at the end of June and -July. ,

Species S.— Harpalyce biangulata '. — (Plate LXIII., Fig. 27.) — This species measures from 13 lines 



to rather more than 1;^ inch in expanse of the fore wings, which have the basal half suffused with olive-brown ; 



the base paler ashy green, with several slender darker stvigse ; the broad central fascia dark olive brown, witli the 



outer margin in the middle with two strong angles ; beyond this is a white fascia, followed by brown and gray 'i<:i«'tJcJ 



wavy clouds, and several dusky dots, especially along the apical margin ; the hind wings are ashy, generally ^. 



marked with the ordinary strigae ; the apical inargin with an olive tinge. The green colour fades into a dull buff 



hue. Found in woods in June, but not common.

Species 9. — Harpalyce silaceata '". — (Plate LXIII., Fig. 28.) — Tliis species measures about 1^ inch in 



expanse of the fore wings, which are of a pale ashy white ; the base with a rather broad brown fascia, followed _ ■ 



by a very broad central brown bar, deeply angulated in the middle of the inner margin, and witli the outer rf^>-,„,ix, 



margin trilobed, the middle portion being occasionally insulated by the pale branches of the median vein ; ^- -^ 



towards the apex is a series of irregular-sized brown conical spots, and a patch of the same colour on the apical 



margin, the preceding space being more or less clouded. The hind wings are whitish, with the space beyond a 



pale angulated fascia rather more dusky. The caterpillar is described by Stephens as being bright green, with 



a duller lateral line, and a black dorsal one, and some yollowish-green spots behind, and as feeding on tlie aspen. 



Taken in July and August. A widely-dispersed, but not common species.

. Species 10. — Harpalyce corylata". — (Plate LXIII., Figs. 29, 30, 31.) — This species measures about 



J^ inch in the expanse of the fore wings, which have the base fulvous brown, followed by two dentated white .c 



strigsB, the space between which is grayish-buff; the central bar is fulvous-brown, with a black stigma, followed fyS, 



by a dentated white line ; the apical portion of the wing varied with buff, brown, and white shades, and an 



irregular- waved subapical striga, interrupted by a pale patch at the apex and in the middle of the apical margin; 



the hind wings pale-grayish, with light dusky strigae. The caterpillar is pale-yellowish, with a whitish lateral 



line ; it feeds on various trees, and the moth appears in -June, in woods.

Species 11. — Harpalyce unilobata ". — (Plate LXIII., Fig. 32.) — This insect, as well as Ph. 4-annulata, 



Haworth, Stephens, and Wood, fig. 565, are considered by Mr. Stephens as probably varieties of H. Galiata. Jti^i t-- ■' - 

 The former has the fore wings ashy and slightly clouded, with the base, and a dark broad central bar of brown .''^i 



streaked with black, having a single rounded lobe on its outer edge ; the extremity of the wing more dusky.
