Yol. 68.] INSECTS FEOM THE AECTIC EED. 241 



Appe:n^dix lY. — Report on the Insect- Eemaii^s. 

 By Chaeles 0. Waterhotjse, I.S.O., P.E.S. 



I HAVE examined the insect-remains from the Arctic Bed at 

 Bonder's End, and find that the following groups are represented : — 



Oarabid.e. 



Anchoraenus ? (several 



species). 

 Ci/rtonotus sp. 



Dytiscid^. 



Pterostichus sp. 



Carahus sp. 



Elaphrus cupreics Dufts. 



HYDROPHILIDdJ. 



Hi/drobius fiiscipes L. 



ApiIODIIDiE. 



Aphodius. j Mgialia ? 



CURCULI0NID.E, 



Oiiorhynchiis (several species). 



PllYTOPHAGA. 



Bonacea. 



The above are mostly ground-beetles and weevils, nearly all 

 water or marsh-insects. The commonest forms of the Carabidae 

 appear to belong to the genus AncJiomenus^ but the species are not 

 known to me. A thorax is almost certainly a Cyrtonotus, of about 

 half the size of our British species. 



The Ulaphrus cupreus, which is represented by an elytron, lives 

 on the mud at the side of lakes. Hydrohius fuscipes is a common 

 pond species. The Donacea is very near to D. sericea, which is 

 found in Sphagnum, but is more rugose. It may be a variety of 

 that species. 



The majority of the forms present I am unable to identify as 

 extant British species, and the collection certainly suggests con- 

 ditions that differed greatly from those of the present day. 

 Unfortunately, I am quite unable to attempt the work of comparing 

 these insect-remains with the species of IS'orthern Europe.
