may hope to find the larvae of Cerostoma asperella 

 and Gelechia rhombella ; and from off the bark of pear 

 trees the pupae of Gelechia nanella may be collected. 



On the bird-cherry (Primus Padus) the larva of 

 Hyponomeuta Padi occurs, while on oaks we may 

 find the larvae of Cerostoma sequella and Gelechia 

 gemmella (mining the leaves ?) ; and on the orpine 

 ( Sedum telephium) we may perhaps find the larva of 

 Hyponomeuta vigintipunctatus, and descending from 

 birch trees, in their newly made cases, the larva of 

 Incurvaria pectinea may be observed. 



On Chcerophyllum sylvestre the larva of Depres- 

 saria Weirella may be found, while under the leaves 

 of pear, oak and beech, in a slight web, the pretty 

 larva of Phibalocera Quercana devours the under 

 epidermis and parenchyma of the leaves, making brown 

 blotches. 



On elm, alder, hornbeam and nut we shall find 

 commonly the larva of Coleophorafuscedinella, while 

 on the leaves of Genista tinctoria the larva of Coleo- 

 phora vibicella occurs, and in bramble leaves the 

 larva of Nep. aurella ; while in fungi on hornbeam 

 we shall find the larva of Tinea corticella, and the 

 larva of Gelechia sequax in the shoots of the common 

 sun cistus (Helianthemum vulgar -e), and that of G. 

 populella on poplars, sallows and birches. 



And now the larvae of the delicate, graceful and 

 beautiful " Plumes" (Pterophori) demand our atten- 

 tion. These larvae are all hairy, and feed mostly on 

 the under side of the leaves of their respective food- 

 plants. Under the leaves of the burdock (Arctium 

 Lappa) we shall find the larva of Pterophorus galac-
