Gracilariidae. 



Gracilaria alchimiella, Sc. (swederella, Tknbg.). 



This pale purple and yellow insect occurs among oaks in the 

 Gardens. Its habit of sitting with its head much raised, gives it a 

 striking appearance when at rest. 



G. stigmatella, F. 



Only one imago has yet been captured, but the " cones " of the 

 larvae were frequently noticed in A. and P. on poplar and willow 

 last autumn. The larva twists a portion of the leaf into a cone- 

 shaped domicile, and feeds in the interior. The imago hybernates, 

 and may be met with in the spring, 



Ornix betulae, Stn* 



Not rare on the birches in A. The larva lives within a domicile 

 made by folding over a portion of the leaf. 



Lithoeolletis hortella, F. 



One taken by Mr. A. L. Simmons. This is a local species, and 

 appears to be rare in this district. 



L. alniella, Zell. 



In the alder plantation near the lake. 



L. ulmifoliella, Flub. 



Among the birches in May. It appears to have nothing to do 

 with elms. The larva lives in a mine on the underside of birch 

 leaves. 



L. viminiella, Stn. 



One specimen bred from mines on the underside of the leaves 

 of Salix caprea. 



L. comparella, Zell. 



Common in the gardens at rest on the bark of poplars. The 

 larva makes mines on the underside of the leaves of Populus alba, 



-P. nigra, and var. pyramidalis. 



Tischeria marginea, Haw. 



Common amonsr brambles in Q. The larva makes whitish 



cornucopia-shaped mines in leaves of bramble. 



Lyonetia clerkella, L. 



Occurs in P. It is an interesting little moth. The larva makes 

 bold galleries in the leaves of apple, cherry, &c. When full fed it 

 leaves the mine and spins two silken strands along a leaf, which 

 cause it to buckle. On these strands it then forms a cocoon which 

 hangs like a hammock between them. Here the pupa rests till 

 the little white moth comes forth. 



Phyllocnistis suffusella, Zell. 



The mines of this species are common on the leaves of poplar 

 in the Gardens. The larva is very peculiar in appearance and 

 habits. It has no legs but a long forked ^JJ™*™ 1 *? a 

 lepidopterous larva, and lives only on the juice of the leaf. When
