78 BRITISH MOTHS 



CHLORISSA, Stephens. HIPPARCHUS and MACARIA, pars, Curtis. 

 The species of this genus are distinguished from the alHed preceding groups by having the wings more or 

 less tinged with green, and the posterior ones more or less angulated in the middle of the posterior margin ; the 

 palpi are slender, but porrected beyond the front of the head ; the antennae of the males are subpectinated, 

 nearly to the tips in some species, but ciliated through their entire length in others ; and the hind tibiae of the 

 males are more or less incrassated, and in some species furnished with only a pair of spurs at the tips, thus 

 approaching the insects of the preceding genus. 



Species 1. — Chlorissa vieidata' — (Plate LXXIII., Fig. 14) — Measures 10 or 11 lines in expanse ; 

 wings bluish green, with an almost obsolete striga preceding, and another beyond the middle of the wings, the 

 latter also extending across the hind wings ; the fringe with a reddish tinge. Rare ; taken in the New Forest 

 and elsewhere, at the end of May and in June.

Species 2. — Chlorissa cloraria, Hiibner ? Wood, fig. 735. — Under this name Mr. Stephens doubtingly 

 describes a specimen, which he considers distinct from the preceding ; measuring nine lines in expanse, and 

 having all the wings pale green, with a single whitish striga placed behind the middle, fringe entirely green. 



Species 3. — Chlorissa Thymiaria" — (Plate LXXIII., Fig. 15, 16) — Measures from 9 to 14 lines in 

 expanse ; wings dull grass-green, with a flexuous pale whitish striga before, and another of the same colour much 

 waved, also crossing the hind wings beyond the middle ; fringe whitish with brown spots. Common in woods 

 at the end of June. The caterpillar is slender, attenuated in front ; green varied with dark patches on the back ; 

 marked with white dots, and with a brown head ; it feeds on the oak, whitethorn, &c.

Species 4. — Chlorissa pdtataria ' — (Plate LXXIII., Fig. 17) — This delicate species measures 10 or 11 



lines in expanse ; wings pale green, with two almost obsolete whitish striga running across the middle of the 



wings : the first less conspicuous on the latter, slightly incurved, and almost without undulation ; but the second 



Xo^" . striga is undulated, fringe greenish. The green colour of the wings soon fades to a delicate white. Very com- 



^.2 mon in woods at the end of May. This species differs from all the preceding, by having two pairs of spurs in the 



male tibiae.

TIMANDRA, Duponchel. MACARIA, pars, Curtis. 

 These insects have the hind wings angulated in the middle of the hind margin, like those of the last genus; 

 from which, however, they differ, not only in the duller colours of their wings, but also in the diagonal fascia 

 running across them ; the antennas of the males are slightly pectinated ; the palpi are porrected ; the fore wings 

 acute at the tips ; and the hind tarsi of the males are dilated, and destitute of spurs ; the females having two 

 pairs of those appendages to the same limbs.
