ANOPLURORUM BRITANNIA. 67 



misignatus as parasitic on the Raven, but, as he does not 

 give the specific character of that species, I have no means 

 of identifying it with Mr. Thompson's specimens ; but, lest 

 I should uselessly increase species, I have ventured to 

 quote his synonyms. 



4. DOCOPHORUS PICJE. Denny. (Louse of the Magpie.) 

 Plate I. Fig. 9. 



Head and thorax dull chestnut and shining, the latter 

 margined with black ; abdomen pale yellow white, lateral 

 fascia pitch colour ; legs with black annuli. 



Head triangular, with two black diagonal bands extending 

 from the trabeculse to the occiput; antennae rather thick, 

 pale brown ; trabeculae large, sub-triangular ; prothorax 

 nearly orbicular, slightly channelled in the centre, lateral 

 margin black ; metathorax transversely triangular, superior 

 margin rotundate, with a fovea at each side of the base of 

 the prothorax, the lateral margin black ; abdomen elongate, 

 ovate, pale yellow-white, and hairy, the first seven seg- 

 ments with a pitch-coloured lateral fascia on each side, the 

 eighth entirely pitch colour, ninth, pale like the central 

 space ; legs pale brown ; femora and tibiae with black annuli. 

 Length f. 



The only specimen of this species which I have seen, 

 was forwarded by Rev. L. Jenyns, from the Magpie 

 (Pica caudata).
