exhibited to the Society. Since that time the author has continued 

 his researches; and the object of the present communication was to 

 show that he considered he had discovered the insect to which these 

 exuviae belong. His reasons for inferring that the insect now de- 

 scribed is the one produced from the exuviae before mentioned, are 

 founded— 1st, on the habitat, the exuvi®, pupa, and imago having 

 been found on the same leaf of Acer campestre ; 2nd, on the colour 

 and texture ; 3rd, on the general form and aspect ; and 4th, on the 

 similarity of the details of the antennae, and other particulars, among 

 which the change of the leaf-like appendages in the pupa to corre- 

 sponding bristles in the perfect insect, was mentioned, leading, in his 

 opinion, to the inference that the Phyllophorus testudinatus, as he 

 proposed to call it, is the pupa of an undescribed species of Aphis, 

 forming a new species, if not a new genus. — J. W.
