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 ehns, of the leaves of 

 which it eats the upper and lower epidermis. I have twice found 

 a Buccnlatrix larva on oak-leaves, probably of this species ; but 

 have not hitherto observed a mine in the oak-leaves, such as these 

 larvfe may be expected to make.

\\c-Ai\fidvoHS. Face pale yellowish. Autenupe fuscous ; basal joint 

 pale yellowish. Anterior wings pale ydlowisJi -ochreous, with four 

 brownish spots on the costa and two on the inner margin ; the first 

 costal spot is sometimes contlucnt with the first dorsal spot, forming a 

 broad angulated fiiscia, 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.

Head pale grey or fuscous. Face whitish. Antennae fuscous, basal 

 joint whitish. Anterior wings dirty whitish, vmch irrorated with fus- 

 cous ; a fuscous patch extends alo?ig the costa to the middle of the wing, 

 beyond this arc two fuscous s])ots 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 s])ot, 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 UJmella.
