 individuals. Perhaps the most interesting shell found was Acan- 

 thinula lamellata among dead beech leaves in Hackfall Woods.

FIELD NOTES. 



Death's Head Moth at Arncliffe.— A Death's Head Moth 

 was found by two boys on the village-green on Saturday, June 

 8th last. I am not aware that a specimen of this beautiful 

 moth has ever been seen before in this valley, which is 750 feet 

 above the sea at the place where the moth was taken. — W. A. 

 Shuffrey, Arncliffe Vicar„^e, June 12th, igi2. 



Leptothorax acervorum in North = East Yorkshire. — 



When at the British Museum lately, Mr. Meade-Waldo showed 

 me an insect of which Mr. Donisthorpe desired to know the 

 locality. It was in the Saunders collection, and when looked 

 at with a lens the label was plainly ' Goathland,' in N.E. York- 

 shire, but by whom or when it was taken is not evident. This 

 is an important record for our county. — W. Denison Roebuck, 

 Leeds, 21st June, 191 2. 



Rhyncholophus niger. — During the last month I received 

 from Mr. W. P. Winter, of Shipley, some mites, among which 

 I found a Rhyncolophus new to me. It was in colour a deep 

 black, but in other respects it resembled R. communis. No 

 new figures are therefore necessary as those in The Naturalist 

 for December 1910, page 428, will serve every purpose. I may 

 say that the mandibles which are not there figured, are sword- 

 like, and I could see no serrations such as are seen in Erythrceus 

 (this should be Ritteria) in the May number of The Naturalist 

 for 1907, page 180. — C. F. George, Kirton-in-Lindsey.
