This specimen was taken January 20th, 1872^ 
During that winter the viviparous females of both 
kinds continued to breed in the open air, and many pupse 
were coming forward, though previously the minimum 
temperature had been as low as 25° Fahr. During 
this severe weather the brown variety was very 
common on the half-evergreen rose bushes. Kalten- 
bach thinks this red variety might prove to be Xystus 
erythrocepJialus of Hartig. 
The emergence of the imago from the pupa has 
been in a general manner described in the section 
relating to the metamorphosis of Aphis. In Plate II, 
fig. 2, will be seen a representation of the curious 
process of exuviation, and also a drawing of the empty 
and entire skin shed by the insect,
