the female occur on the dunes; P. astrarche, rare ; Amorpha popult, 
common ; Metopstlus porcellus, common on bedstr ‘aw flowers on the 
dunes; Dicranura vinula, common where poplars abound; Pygera 
anachoreta, two broods, first in May, second in July, not uncommon ; 
Dasychira pudibunda, common; EHuproctis chrysorrhwa, very 
common on the dunes, where all the vegetation is eaten up by the 
larvee (some fine forms of the male occur ‘with two black spots at the 
inner angle and occasionally one at the apex of the fore wings) ; 
Porthesia similis, common: Stilpnotia salicis, perhaps the commonest 
moth in July ; Malacosoma neustria, rare ; Lasiocampa quercis, very 
common, and efforts at assembling mules to a bred female were 
attended with great success; L. trifolii, fairly plentiful on the dunes; 
Cosmotriche potatoria, common; L. quercifolia, rare; Spilosoma 
menthastri and S. lubricipeda, tolerably abundant ; S. mendica, rare ; 
Diacrisia santo, very common on the dunes in early July ; Arctia 
caia and A. villica, very common in similar situations; Hipocrita 
jacobee, common on the dunes. Of the Noctuze: Agrotis segetwm, 
A. corticea, A. nigricans, A. exclamationis, Noctua axanthographa, 
common; Triphena pronuba, T. orbona, T. tanthina, fairly 
common; Apamea_ secalis, abundant; Xylophasia monoglypha, 
common; Prothymua viridaria, rare; Camptogramma bilineata, 
common; Hupithecia oblongata, EH. assimilata, Cilix glaucata 
(spinwla), not uncommon ; Perizoma albulata, rare; Abraxas grossu- 
lariata, very common; 4ygena filzpendule abounds in meadows ; 
Trochiliwm apiformis, not uncommon where poplars are abundant. 
This brief list gives a general indication of the lepidopterous fauna 
of a district near the coast in the north of France. Had more time 
been at my disposal the list of species I think would have increased 
accordingly.—_JamEs W. Brown; H. Q. Friends’ Ambulance Unit,

Lycmnips IN NorTHERN FrANcE.—May I trespass on your 
courtesy by asking for information about two insects I have taken 
this evening on a bit of rough, sandy ground in the Pas de Calais ? 
They closely resemble Polyommatus icarus 2, but differ as follows : 
Both have blacker ground colour with fringes very slightly lighter 
than ground colour, though in one the apex of fore wing on both costa 
and outer margin is white. This specimen has no blue on upper side 
fore wing ; the orange spots are well marked, that nearest the apex 
being almost white, however. No discoidal spot fore wing. The 
other specimen has no orange spots, but has a sharply defined purple 
or violet basal blotch-—it is about normal in size for zcarus, the 
other being smaller. The under sides of both resemble tcarus, with 
well-marked orange spots, fringes paler than above and two basal 
spots fore wing, but all markings on under side are rather more 
definite than usual. This is my first season with the continental 
butterflies, and the only book I have is Kane, which is rather out of 
date and certainly does not mention zcarus with dark brown fringes. 
IT am rather disappointed to find the insects here so British in 
character, the only non-British species as yet being, I think, 
Glaucopsyche cyllarus §. However, I have taken Nola centonalis and 
Parascotia fulaginaria, also Melitea athalia, Rott., and some decent
