NOTES ON THE BUTTEKFLIES OF THE SOMME. 

 By Lieut. Cecil Martin, A.S.C. 



During 1916 I was in the " Somme area " from the first 

 week in May till August, and travelled over most of the wide 

 stretch of country lying between St. Kiquier, near Abbeville, 

 and Albert. I had not much time for collecting, but did better 

 than I expected, owing to the locality being such a favour- 

 able one. 



In mentioning the villages, woods, etc., near which some of 

 the less common species were taken, I hope I may be of 

 j)ossible assistance to other collectors out here. 



Papilio machaon. — Common throughout the Somme area. 

 The second flight, which took place at the end of July, appeared 

 to be more numerous than the first flight in May. 



Pieris hrassicce, P. rapce, P. napi were common everywhere, 

 both first and second broods. 



Aporia craUsgi. — Two rather worn males taken in July at 

 Frechencourt. 



Euchloe cardamines. — Plentiful near the river ; females 

 especially numerous. 



Colias hyalc. — Seen in suitable fields throughout the summer. 

 I think there were three broods during the season. C. edusa 

 not seen. 



Gonepteryx rhamni very common in the Foret de Vignacourt 

 during early August. 



Apatura iris. — Four seen in early July at Frechencourt. One 

 male captured while feeding on some moist substance in a lane 

 bordering a small wood. Probably also found in the Foret 

 d'Vignacourt, where there are plenty of fine oaks. Unfortunately, 

 I was unable to get there in July. 



Liinenitis sihylla. — Plentiful in two small woods at Frechen- 

 court. Many fine specimens taken. 



Polygonia c-album. — A few specimens, all var. hutchinsoni, 

 taken near Frechencourt. 



ArascJinia levana. — One taken near Longpre in May. The 

 second brood, var. prorsa, produced some tine specimens in 

 July at Frechencourt. 



Eugonia polyddoros. — About sixty caterpillars collected and 

 reared at Belloy-sur-Somme in May. Freshly emerged butter- 

 :flies also seen in August at Talmas.
