but no perfect specimens. (I kept a good one out, before 

 sending the marl to Mr. Gilligan). Small pebbles of an 

 opalescent quartz, beautifully rounded, also occur. 



My thanks must be expressed to Messrs. Ingham and 

 Gilligan, for so kindly examining and reporting upon the 

 moss and marl, respectively.

ENTOMOLOGY. 



Dytiscus circumcinctus Ahr. in the East Riding. — On 

 August 3rd and loth, 191 1, I captured several Dytisci in a pond 

 by the River Derwent at Bubwith, and at the time put them 

 away in my collection as marginalis L. However on sending 

 a smooth § to Mr. G. B. Walsh, he discovered that it was 

 circumcinctus Ahr. On working through the beetles I find 

 that there are several marginalis L. and six circumcinctus 

 Ahr. (4 (^s and 2 smooth $s). I believe that the only other 

 Yorkshire capture was about forty years ago, when Archdeacon 

 Hey and the Rev. W. C. Hey took a single smooth ^ at Ask- 

 ham Bog. — W. J. Fordham, Bubwith. 



Coleoptera at Riccall and Skipwith. — The following is
