furnish me with a specimen. The size and figure of the 

 lateral fasciae on the abdomen are very variable. In some 

 specimens they are nearly united, while in others the sutural 

 white lines are very broad; again, the metathorax, which is 

 generally uniform in colour with the prothorax, is some- 

 times very dark and obscure.

Although I have never seen this species, I consider it- 

 ought to be enumerated, and have therefore given Scopoli's 

 original description for reasons to be seen hereafter. If it 

 is really distinct from the preceding, it will most probably 

 be a British species, as the Astur Palumbarius belongs to 

 our Fauna. But not a little obscurity hangs over it, and 

 diversity of opinion exists ; Dr. Burmeister says it is found 

 only on the Goshawk, while Scopoli, the Fabriciuses, Mul- 

 ler, Stewart, Stephens, and Turton quotes it as infesting 

 Owls. Now Scopoli's description given above, agrees in 

 every respect with the preceding species, excepting the 

 abdomine linea dorsali nigri utrinque, and the specific name 

 of Nitzsch's would suit that species admirably, which has a 

 broader front to the head than any other species I am ac-
