to those who are not ornithologists. I strongly advise any mem- 

 ber of our Club who may have the pleasure of travelling in Swit-

VIII.—NOTE ON THE MOUTH-ORGANS OF INSECTS. 



By Mr ANDREW" MOFFAT, Secretari/. 



[Read Jan. 26, 1882.) 



The object of this note being solely explanatory of a series of 

 microscopical preparations which was exhibited in illustration of

The mouth-organs of the following insects, among others, were
