14 REPORTS. 



Report of the Antiquarian Section. 



There lias not been much to bring to notice during the 

 past year. The continuance of the war has prevented excur- 

 sions from taking place, but a close watch has been kept on 

 any likely discoveries. 



The most important archaeological feature of the year 

 has been a short paper by Col. T. W. M. de Guerin on a 

 marking on one of the capstones at the Dolmen of Dehus, 

 read at the November meeting. The paper and the drawing 

 of the marking are published in this number. 



The markings or sculptures on Dolmens are not rare by 

 any means, especially in France. There is the well-known 

 example of Gavr'Innis, but in this case the sculptures are on 

 the props. In the Channel Islands, however, no markings 

 which are clearly the work of man, have previously been disco- 

 vered on Dolmens, and it is to be hoped that this discovery will 

 lead to a more thorough examination of the Dolmens and the 

 discovery of others markings.

Report of the Entomological Section, 1917. 



The spring months were distinctly hostile to entomologists. 

 March and the first half of April were very cold, Avith occa- 

 sional snow showers, but on April 20th appeared the first white 

 butterfly, an unsuspected scout of what was to prove a 

 veritable Air Raid Before the end of May the three species 

 of our native Pierids were everywhere in profusion, and their 

 numbers increased daily till in the beginning of July they 

 were augmented by the emergence of the second brood which 

 overlapped the first. After this, the extraordinary abundance 

 of the " Whites " was painfully noticed by many persons not 

 interested in entomology, for they committed great ravages 

 among the cabbages. There was also a third brood at least of 

 the two smaller species, P. rapce and P. napi, and I strongly 

 suspect even a partial fourth, as fresh specimens were obtain- 

 able as late as October loth. From most parts of England 

 we hear the same tale, and this superabundance of a common 

 butterfly is the chief note of interest of the year. Another 

 butterfly which was quite exceptionally common was the 

 "Meadow Brown," Epinephile jurtina, which flew in clouds 

 about the hedges and borders of the meadows at Pleinmont. 

 I took a nice aberration of this species in which the centre
