British species of Psr/llid<2. 555 



green or greenish-yellow. Tarsi : 2ncl joint entirely, or 

 apex only, and clmvs brown. 



Abdomen pale green. 



Length 1 \ line. 



The delicacy and transparency of this species will sepa- 

 rate it from all others. 



Flor says that it is not uncommon with him from June 

 to October, upon the spruce fir (^Pinus ahies). I have 

 only met with two examples ; one in the August of this 

 year, amongst rubbish at the bottom of a hedge, and the 

 other in September, 1869, in the Sallow Pit, Lee.

After carefully reading and comparing the description 

 of T. galii and velutina, as set forth both by Forster and 

 Flor, I have come to the conclusion that the differences 

 are more imaginary than real, and I have therefore ranked 

 them as one species only, until I have examined more 

 specimens.
