My chief object was butterfly-collecting, and, considering the in- 

 clement and backward season and that one of the three days the 

 wind was rather high, the fact of seeing or taking over thirty 

 species, I conclude, is sufficient evidence of its capabilities, w^hich 

 the odds and ends of the other orders, gathered without effort, tend 

 to confirm. 



There is a very convenient (but not frequent) train service to and 

 from Dieppe, which enables one to approach and leave the forest at 

 various points without the necessity of retracing one's steps. Apart 

 from entomology the whole district is interesting ; the scenery is 

 charming, there are Celtic and Roman remains hard by, a ruined 

 castle on a neighbouring hill, and, above all, the celebrated field of 

 battle on the slopes of the forest itself. 



The butterflies captured or noted were : 



Pieris brassicce, P. rapa, and P. napi ; these three whites were in 

 about equal numbers, but not numerous. 



Euchloc cardamiues ; one ^ seen and taken near St. Nicholas. 



Colias hyale ; one seen at Arques, another near Sauchay. I did 

 not see edusa. 



Gonepteryx rhamni ; fairly common in the forest, but, of course, 

 in rags. 



Aglais ( Vanessa) urtiae ; one fresh specimen at Eugleville. 



Eugonia ( Vanessa) polychloros ; one seen near Sauchay. 



Pyrameis cardui ; a number of w^orn specimens near St. Martin. 

 P. atalanta ; fairly common near the main road through the forest. 



Dryas paphia ; one ^ seen near Archelles. 



Argynnts adippe or A. aglaia ; one seen near Ancourt. 



Brenthis {Argynnts) euphrosyne ; a few remnants in the forest. 

 B. (A.) selene ; the commonest species in the forest. 



Melitcea cinxia ; a few in the forest and on the hillside near 

 Ancourt ; some seemed freshly emerged, but others were in rags. 

 M. aurinia : a few worn specimens on the hillside just below the 

 forest, opposite Sauchay. 



Pararge {egeria var.) egerides ; common in the forest along dark 

 portions of the road, but not easy to catch. P. {Sa/yrus) megirra ; a 

 few in the forest, some worn. 



Ccenonynpha arcania ; I do not know whether this is a new 

 locality for this species. Lang gives its habitat, woods in Central 

 and Southern " Europe. Kane says, abundant in most parts 

 of France. I found it sparingly in the forest itself, but on 

 the hillsides facing Sauchay it was in profusion ; three at a time 

 in the net was not unusual. Apart from the mountain variety, 

 darwiniana, I was not aware this species varied much ; my 

 three dozen specimens were netted without discrimination. I regret 

 now not taking more. However, my captures work out satis- 

 factorily, exhibiting the whole range of variation as described by 

 Kane and Lang, with the exception of darwiniana and an example 

 showing " a second small apical eye-spot, which sometimes appears
