[This bee was undoubtedly Bo7tibus si/lvarwji, a very 

 generally distributed species. — Ed.] 



Lepisma saccharina. — Will you kindly name the enclosed 

 insect for me ? It was found by myself in a chest of China 

 tea, on August 18th. — F. B. Street. 



[The insect forwarded, which was found in the chest of 

 tea, is that well-known little household pest, the common 

 fish-scale {Lepisma saccharina). These degraded little insects 

 are especially partial to the contents of the store-room or 

 book-case. They are of nocturnal habits, swiftly running 

 away to some shelter when disturbed by day. Sir John 

 Lubbock from time to time published his "Notes on the 

 Thysanura'^ in the Linnean Society's Transactions: these 

 subsequently developed into that important and beautiful 

 " Monograph of the Colletnbola and Thysanura,'' issued by 

 the Ray Society in 1873.— E. A. F.] 



Celery Fly. — Will you kindly let me know the name of 

 the insect of which the enclosed represent the larva ? They 

 have almost destroyed the whole of the leaves of my celery 

 (six rows of ten yards each). My gardener tells me he has 

 seen them some years ago, and that they will not injure the 

 edible part of the plant. — W. H. Heaton. 



[These small green maggots, which live in blotches between 

 the cuticle membranes of the celery leaves, are the larvae of a 

 pretty Dipterous fly belonging to the genus Trypeta of 

 Meigen. They blotch the leaves only, and are not injurious 

 to the stalks unless present in extraordinary numbers, or from 

 a very early attack on the young late plants. This year 

 they are, however, especially abundant and destructive in 

 and around London ; 1 know of rows in metropolitan gardens 

 of which the leaves are couiplelely gone, looking as if they 

 had been scorched or burnt up ; in such cases they must be 

 injurious to the well-being of the plants. Pinching the larvae 

 when in the leaf is a sovereign remedy where practicable and 

 attended to. It is also usual to grow celery on almost the 

 same ground year after year; where the insect is troublesome 

 this should be avoided as much as possible. — E. A. F.]
