MICROPTERYX. ; AB 
the middle of the inner margin is a conspicuous rather triangular spot of 
the pale ground-colour, which reaches fully half across the wing ; on the 
costa, a little beyond it, is a small less distinct pale spot, and there are 
faint indications of a pale spot on the fold before the middle; cilia 
purplish-fuscous, opposite the pale spot of the inner margin pale golden. 
Posterior wings pale grey, towards the apex purplish, with paler cilia. 
Taken freely, along with the preceding, by Mr. Salt, near Shrews- 
bury, in April, 1853, in a wet place among birches.

Head and face greyish-fuscous. Antenne dark fuscous, more than 
half the length of the anterior wings. Anterior wings purple, irrorated 
with pale golden, and with a large pale golden spot beyond the middle 
of the inner margin, reaching half across the wing; cilia grey. Pos- 
terior wings grey, with a slight purplish tinge towards the apex; cilia 
grey, paler towards the anal angle. 
Common among birches in April. (In Continental specimens 
of MW. amentelia 1 have before me, the anterior wings appear 
shorter and more rounded than mn WZ. semipurpurella.)

anticarum equantibus. Exp, al. 5 lin. 
Head and face dark fuscous, mixed with grey. Antenne dark fus- 
cous, about half the length of the anterior wings. Anterior wings pale 
golden-green, almost entirely suffused with purple, leaving however a 
conspicuous yellowish-white spot beyond the middle of the inner mar- 
gin; this spot is rather narrow, slightly curved outwardly, and reaching 
about half across the wing ; cilia grey. Posterior wings pale grey, with 
a purplish tinge towards the apex; cilia greyish. 
Occurs among birches in April. Not uncommon at West 
Wickham Wood; but does not seem to occur at Darenth Wood, 
where MW. purpurelia is so plentiful.

Head and face greyish, slightly mixed with dark fuscous. Antenne
