 gin chestnut ; posterior femora angulate beneath. Length f . 

 This species has been found on the Blackbird (Turdus 

 merula), and communicated by Sir Wm. Jardine, Bart., 

 Mr. Selby, and Rev. L. Jenyns; the latter gentleman has 

 also taken it from the Fieldfare (Turdus pilaris), and I once 

 found a specimen on the Ring Ouzel (Turdus torquatus). 

 But from the circumstance of its being found on the Black- 

 bird in three different and widely separated parts of the 

 kingdom, I should consider that Bird its proper nidus.
