 contributed notes on " Breeding Experiments with the Black Race 

 of Boarmia repandata (var. nigra),'" and summarized the results as 

 follows : — In 1909 {a) a wild female of the local type form gave all 

 var. nigra ; (6) a wild female var. nigra gave all black moths ; (c) a 

 pairing of nigra male and type female gave all types. In 1910 [a) 

 type X type gave 66-6 per cent, type and 33-3 per cent. var. nigra ; 

 (6) nigra x nigra gave 92 per cent, nigra and 8 per cent, type ; and 

 (c) nigra x nigra gave 96 per cent, nigra and 4 per cent, type ; 

 while in 1911 {a) type x type gave all type ; [b) nigra male x type 

 female gave all nigra ; (c) nigra x nigra gave 95-7 per cent, nigra 

 and 4-3 per cent, type, and [d) a second experiment of the same gave 

 70-5 per cent, nigra and 29-5 per cent. type. In 1910 moths from the 

 broods a and c w&xe used for the cross pairings of type and variety, 

 the others being inbred ; and in 1911 all were inbred. Dr. Tinne

The Manchester Entomological Society. — February 7th. — 

 Mr, J. Mangan, M.A., gave a lecture on " The Larch Sawfly 

 (Nematus erichsonii) and its Parasites." After dealing with its 

 life-history, habits, and destructive powers, he detailed the various 

 natural checks found to affect this insect : — (1) Parasites. Mesoleius 

 aulicus has been found (in the Lake District) in the greatest 

 numbers, and is apparently the most valuable natural check. 

 Microcryptus labralis also occurs ; examples of each were shown. 

 (2) A fungus attacks the sawfly cocoons. (3) The field-vole [M. 

 agrestis) occasionally destroys as many as thirty or forty per cent. 

 (4) Birds, such as chafiinches, tits, and starlings, are useful. — Mr.
