292 LYONETIDA, 
of an oval shape and very distinct; cilia pale ochreous, with some fus- 
cous scales. Posterior wings grey, with paler cilia. 
Common in May, June, and August, among oaks; here it never 
frequents elms. According to Mann’s observations, the larva de- 
scends when full-fed in September, from the elms, of the leaves of 
which it eats the upper and lower epidermis. I have twice found 
a Bucculatrix larva on oak-leaves, probably of this species; but 
have not hitherto observed a mine in the oak-leaves, such as these 
larvee may be expected to make.

ochreis, maculis guatuor coste obliquis brunneis, secunda abbreviata,

Head fulvous. Face pale yellowish. Antenne fuscous; basal joint 
pee yellowish. Anterior wings pale yellowish-ochreous, with four 
rownish spots on the costa and two on the inner margin; the first 
costal spot is sometimes confluent with the first dorsal spot, forming a 
broad angulated fascia, the second costal spot is very small, the third 
is darker than the others, and is continued to the anal angle, the fourth 
is in the apex of the wing; between the two last is a small black spot 
on the disc; in the middle of the inner margin is an oval fuscous spot, 
on its inner edge with some black scales ; cilia pale ochreous. Posterior 
wings pale grey, with paler cilia. 
Perhaps not specifically distinct from the preceding; I have a 
specimen taken among oaks in August.

Exp. al. 4 lin. 
Head pale grey or fuscous. Face whitish. Antenne fuscous, basal 
joint whitish. Anterior wings dirty whitish, much irrorated with fus- 
cous ; a fuscous patch extends along the costa to the middle of the wing, 
beyond this are ¢o fuscous spots on the costa, which are joined to- 
gether on the disc by a small black dash; near the base of the inner 
margin is a cloudy fuscous patch; towards the anal angle is a fuscous 
oval spot, on its inner side margined with black; in the apex of the 
wing is a black spot, and some black scales are carried round it through 
the pale ochreous cilia. Posterior wings pale grey, with paler cilia. 
Abundant in hedges in May and June. ‘The larva at first 
mines within, subsequently feeding externally on the leaves of the 
hawthorn ; the pale ochreous ribbed cocoon is more elongate than 
in Ulmella.
