4028 Insects. 



Lineolea. The larvae feed in April and May on Ballota nigra and 

 on Stachys sylvatica : on the former plant frequently abundant, 

 on the latter more sparingly. Von Heyden's Stachydella (Linn. 

 Ent. iv. 327) is certainly only this species. 



Argentula. The larva feeds on the seeds of the yarrow (Achillea 

 Millefolium) in September and October, not however changing 

 to the pupa state till June : hence the insect is difficult to rear. 



Hemerobiella. The larva feeds on fruit-trees in May : not uncom- 

 mon in gardens at Hammersmith, Putney, &c. Fischer-von- 

 Roslerstamm has figured the transformations of this species in 

 his pi. 69. 



Laricella. The larva in April and May on larches. The case and 

 discoloration of the larch-leaves are figured by Hiibner (Larvae, 

 vol. iii., Tineae, vi., Alucitiformis, A. a.), and by Ratzeburg, 

 (2Theil, pi. 15, f. 3). 



Albitarsella. The larva feeds on Glechoma hederacea during the 

 winter and early spring months. According to Bruand it feeds 

 also (lividellci, Bru.) on Origanum. For figures of the larva, 

 case, and discoloration of the leaf, see Ent. Trans, n. s. ii. pi. 

 11, f. 1. 



Nigricella. The larva feeds, in May and June, on hawthorn, apple 

 and pear : a case on the pear is figured by Reaumur, (pi. 7, f. 

 7, 8, 9). In many localities the species is excessively abun- 

 dant on the hawthorn. This insect, or an unnamed species 

 closely allied to it, also feeds on the birch. 



Fuscedinella. The larva feeds in May and June on elm and alder. 

 The case and mode of mining are figured by Reaumur (pi. 8, f. 

 1 — 11). Either this same species, or others very closely allied 

 to it, feed on hornbeam and nut. 



Jjuscinicepennella. The larva feeds on roses in May. This had 

 been observed by Reaumur (iii. 99, "C'est sur des rosiers," &c), 

 and a description of its transformations occurs in Bouche's 

 ' Naturgeschichte der Insekten,' (p. 131, under the name of Gry- 

 phipennella). An account of the larva and case appears in 

 Kollar's ' Insects injurious to Gardens,' (see Loudon's transla- 

 tion, p. 180), under the name of Rhodophagella. 



Viminelella. The larva feeds on osiers and sallows in May. This 

 species is first alluded to by Zeller in the Linn. Ent. iv. in a 

 note at pp. 393, 394. The perfect insect closely resembles some 

 of the other unicolorous species, but the larva-case is very dif- 

 ferent.
