SCAKITINA. 



Dyschirius thoracicus Rossi. In Yorkshire the Dyschirii 

 are confined to the sandy parts of the coast line. 



1. S.E. — Cliffs south of Bridlington Quay, where there 

 is loose sand ( W. C.H.); ditto, 'very abundant' ( W. W.F.). 



2. N.E.— Redcar ( W. Hey). 



Dyschirius nitidus Dj. Stephens gives 'shores of the 

 Humber ' as a locality for this species, and the Rev. G. 

 T. Rudd describes it as occurring ' in profusion at 

 Redcar' (1829). Dawson is sceptical about it {nide Geod. 

 Brit., p. 27), and I share his scepticism. 



[Dyschirius angustatus Ahr. A series taken at Bridlington 

 Quay by the Rev. W. W. Fowler was referred to this species 

 provisionally, but is now considered a small variety of the 

 succeeding species]. 



Dyschirius politus Dej. 



I. S.E. — Near Bridlington {Datvso>t, Geod. Brit.). 

 The D. angustatus (J) are almost certainly a small variety of 

 this species, but some often have the denticulation of the 

 anterior tibiae marked. 



Dyschirius salinus Schaum. 



1. S.E. — Bridlington Quay, in company with D. thoracicus, 

 May and July ( IV.C.H.) ; shores of the Humber {Dawson, 

 Geod. Brit). 



Clivina fossor L, Common and general. It is sometimes 

 very abundant in the Ouse flood-refuse. 



2. N.E.— Whitby and Eskdale {H. Pollard); Scar- 

 borough {R.L.) ; Cleveland district {IT. Pollard) ; Guis- 

 borough {E.B. W.). 



3. N.W.— Studley {E.A. JV.) ; Bolton Wood (E.B. W.). 



4. Central.— York ; Selby ( W.C.H.).

 Clivina collaris Herbst.
