172 OCTOBER. 



torum; in beech leaves, L. Faginella and N. Tity- 

 rella; in birch leaves, L. ulmifoliella and the larvae 

 of the new species of Nepticula Betulicola. The 

 larvae is thus noticed in the Natural History of the 

 Tineina, vol. i. p. 22 : — " An amber-coloured larva 

 with green dorsal vessel, making a small contorted 

 gallery, of which the commencement is filled with 

 brown excrement, the latter half having the greenish- 

 grey excrement only in the central portion." 



In alder leaves, on the upperside, we shall find the 

 larva of L. Stettinensis ; while on the underside the 

 larva of L. FrolicMella (distinguishable by its large 

 mine and cocoon), and L. Kleemannella and alnifo- 

 liella, occur. 



In elm leaves the larvae of the beautiful L. Schrebe- 

 rella will be found, together with the yellow larvce of 

 the equally beautiful N. marginicolella, and the gut- 

 formed mine and green larx.ce of the plain N. visce- 

 rella. 



But let us for variety examine that clover-like plant 

 with pea-like seed vessels growing on that hedge bank, 

 the bird's-foot trefoil {Lotus corniculatus). We may 

 perhaps see on some of the leaves white blotches. 

 These are caused by the larvae of Coleophora discor- 

 della, and on turning over some of the blotched leaves 

 we may find a larva in its small curved case, at present 

 hardly the eighth of an inch high. This is an example 

 of a Coleophora larva, which does not quit its case, and 

 form a new one, as is the custom of Col. gryphtpennella, 

 but increases the dimensions of its case by adding new 

 portions to the original one ; and the manner in which 

 this is effected is rather curious, and is as follows : —
