COLEOPIIORA. 221 



Appears in Juno and July among ground-ivy [Glechoma hedc- 

 racea), but rarely met with in the perfect state. Tlie larva feeds 

 from jN'oveinber to April on the leaves of the ground-ivy^ hut 

 only on such plants as grow comphHely in the shelter of a hedge ; 

 the mined places arc at first whitish, but afterwards become of a 

 pale dirty-brown; the case is rather long, slightly curved, dark 

 brown. The larva also (according to Bruand) feeds on Onganum.

Head and face greyish-brown. Palpi paler. Antennte white, annulatcd 

 with dark fuscous ; the basal joint slightly thickened, greyish-brown, 

 not tufted. Anterior wings uuicolorous, fuscous-(5'/«c/(-, witli paler ciha. 

 Posterior wings dark grey, with paler cilia. 



Abundant among hawthorn in June and July. The larva feeds 

 on the leaves of the hawthorn, apple, pear, and sloe in May, in 

 nearly straight cylindrical brown-black cases; the case of the 

 young larva, which commences feeding in antumn, is curved, 

 somewhat like a cornucopia. A larva probably also referable to 

 this species feeds in May on the leaves of the birch.

Head, face, and palpi brownish-grey. Antenna; whitish, annulated 

 with fuscous, more faintly so towards the apex ; the basal joint slightly 

 thickened, fuscous, not tufted. Anterior wings uuicolorous fuscous, 

 more or less tinted with grey, with paler cilia. Posterior wings fus- 

 cous, with paler cilia. 



Abundant among elms and alders in July. The larva feeds in 

 May and June on the leaves of those trees in a brown case, rather 

 stouter than that of niyricellu ; the young larva has a curved 

 case. 



It is of the larva of this species that ]\Ir. Spencc has described 

 the operations, from his own observations, on some larvai upon 

 the alders in the Hull 15otanic Garden (Kirby and Spencc, Lth 

 edit. vol. i. p. 4.^9). Larvre probably referable to this species 

 feed on the luit and hornbeam.
