OX A NEW INSECT, A PARASITE ON TUE SYCAMORE. 



BY THOMAS P. PEBNIE, ESQ. 



INSECT GREATLY MAGNIFIED. 



This curious insect, which I have named provisionally PhyllojyJiora testudi- 

 nacea, occurs in this neighbourhood, on both sides, but especially the upper, 

 of the leaves of the sycamore, {Acer catapestre,) evidently feeding upon its 

 juices. It casts its skin while in the pupa state, which is that in which it 

 is now found. In the complete insect two bristles appear to take the place 

 of each of the leafy appendages with which the sides of the abdomen are 

 fringed. 



I hcxvc recently found it, somewhat sparingly, on the leaves of Acer pseudo- 

 platanus. Having from observation some reason to think it may prove local 

 in its distribution, I shall have much pleasure in sending a leaf with the 

 insect on it, to any person who may be desirous of possessing it, and has 

 not been able to find it. I have mounted a few for the microscope, which 

 may perhaps prove an acceptable medium for exchange.
