NEW ENIGMAS FOR SOLUTION. 



18. A Lithocolletis larva mining the upper side of birch 

 leaves. A few were found by Mr. Scott, in September, 

 1854; none were reared. 



19. A Coleophora larva, feeding on the capsules of Silene 

 inflata. Mr. "Weir found one a few years ago, but when in 

 Paris I saw several in the possession of M. Bellier de la 

 Chavignerie, who (knowing my especial predilection for

20. A Depressaria larva found by Mr. Boyd, May 2nd, 

 (it was then young), feeding on a leaf of parsnip (Pastinaca 

 sativa), under a turned-down corner; this was expected to 

 be Depressaria Douglasella. 



21. A very singular birch-leaf miner discovered by Mr. 

 Boyd, at Lynmouth, July 19th : the young larva makes a 

 very long linear mine (two or three inches!) commencing 

 near the top of the leaf, mining nearly parallel to the midrib, 

 till it reaches the foot-stalk of the leaf; it then mines towards 

 the edge and commences making a large blotch, and after a 

 while it cuts out an oval case in this blotch and descends to 

 the ground. Advised by the sight of the leaves he sent me, 

 I went out and at once found the same larva in my own imr 

 mediate neighbourhood. 



22. A very similar mine I observed on the 29th July, on 

 alder leaves, but was too late for the larvae, they having all
