ferruginous parts duller than in A. raptor ; on tbe other 

 hand, in the darker specimens taken at Torcross the struc- 

 tural characters agree with A. raptor, but the thorax is dark 

 slaty-grey, and the legs all blackish, except for a slight 

 ferruginous tinge at the tip of the femora, and on all the 

 tibise (unless at the tip), and on all (except the tip) of the 

 basal joints of the tarsi ; other specimens, however, exhibit 

 more ferruginous colouring, but never to any great extent. 

 If the Torcross specimens represent a distinct species, the 

 plainest character would lie in the much more blackish hue 

 of the wings as compared with the brownish tinge of the 

 two known species. 



A. celtiber occurs in company with A. raptor at Ilfra- 

 combe, and Mr. 0. G. Lamb has taken it freely at Padstow, 

 in Cornwall ; Haliday recorded it from Smerwick Bay, Kerry. 



2. A. raptor Walk. : common on the sides of rocks and about the 



base of cliffs where washed by the sea on the coasts of 

 Cornw^all and Devon. The "dark form mentioned above may 

 represent an autumnal form. Walker (really Haliday) 

 records it from Torquay and Dundrum Bay, in Ireland. 



3. A. ferox Walk. : in abundance at Totland Bay, in the Isle of 



Wight, and also occurring at Torcross and Whitsand Bay, 

 near Plymouth, and at Padstow, in Cornwall.
