eommon in the liowery hollow, and the ground being very stony 

 chasing examples is difficult as one cannot turn quickly. Occasionally 

 the female has no orange, but it usually has some. Just as Seitz 

 says, Melitcea didyma jyersica frequents ' the crests of stony hills.' 

 They are usually put up settled on the rough ground at the highest 

 part of the stony ridge. This morning (Marcli 24th) I got a very 

 line female, settled with wings spread, on the ground in the sunshine 

 just outside our mess tent, though I have had to ride or walk out 

 some three miles to get any, and it is a great speculation as to 

 whether one gets a few or none. Yesterday I got three Papiiio 

 machaon males at rest on the summit of the stony ridge, but all were 

 damaged. I also got a very dark male of the ' Doll ' butterfly, and 

 a ? Hytha sp., or grayling-like species with tawny patches and two 

 minute spots on the underside of the fore wings. This is abundant 

 in Persia in the summer, and may be common here then. A few days 

 ago (March 12th) we saw two hibernated Pijrameis atalanta, and 

 P. cardui is about in thousands." — F. A. Oldaker ; The Red House,

Notes on some Lepidoptera of the Pas-de-Calais and of 

 THE SoBiME. — ^The following notes, altliough rather late, may be of 

 some interest to other collectors who have visited the districts 

 referred to. Rhopalocera. — Pwpilio machaon : Abundant near 

 Beauquesne, Vignacourt, in 1915, and Albert in 1917. The larva and 

 imago were also seen fairly frequently near Hesdin in 1918. Picris 

 brassiccE, P. rajjo;, and P. napi : Generally common. P. napi 

 swarmed along the low-lying meadows beside the Ancre between 

 Albert and Aveling in 1917. Some dwarf examples of this species 

 were seen near Beauval in 1918. Euclilo'c cardamines : Not very 

 abundant. A few seen near x\vesnes-leComte in 1917, and near 

 Beauval and Hesdin in 1918. Colias hyale : Fairly common in most 

 districts. Goneptcryx rhavmi : Generally abundant. Apatura iris : 

 A half-dozen or so larvae taken near Beauval in 1918. The imago 

 was not seen. Limenitis sibylla: Rather common near Hesdin in 

 1918. Polygonia c-album : One very worn specimen taken at Hesdin 

 in 1918. Eugonia polychloros : The larvte and pupte of this species 

 were to be found commonly at Cavron St. Martin and La Logo. 

 The imago was seen frequently in the Foret d'Hesdin in 1918. 

 Aglais urticce : Usually common everywhere. Vanessa to : Abundant 

 everywhere. Pyramcis cardui: Abundant at Hesdin in 1918. 

 Pyrameis atalanta : Not very abundant. A few were seen at Albert

 About half-a-dozen seen near Beauval in 1918. Ab. prorsa : One 

 seen at St. Gratien in 1915. It was flying very commonly at Albert 

 in 1917. Dryas paphia : Generally common.' In 1918 this species, 

 along with the var. valesina, was very abundant at Hesdin. On 

 many days it was possible to count as many valesina as ixipliia flying 

 over the bramble flowers in this district. Argynnia aglaia: About a 

 dozen examples captured at Hesdin in 1918. Melitaa cinxia : The 

 larva and imago were found sparingly near Beauval and near Hesdin 

 in 1918. Melanargia galatea : Fairly abundant. Parargc cgeria :
