LEPIDOPTERA OF THE BRITISH LINE IN FRANCE. 253 



Among other things I took two perfect Eurymene dolabraria by 

 this method, more otiose than dignified. 



At Hencbin I at last found Opisthociraptis luteolata in sufficient 

 numbers to be a nuisance. I found it far less common in the 

 surrounding districts, but everywhere much more in evidence 

 than it was last year. 



Epiojie apiciaria was a common insect all through the wood 

 at Avesnes. 



Angevona p)rnnaria occurred near Fruges, and was very 

 common in Belgium. 



Hyhcernia leiicophcsria, II. marginaria, and Anisopteryx cescu- 

 laria were all abundant in several woods between St. Pol and 

 Arras. 



Phigalia pedaria was common in the same woods, and I took 

 Apocheima hispidaria at Avesnes. I saw no specimens of these 

 insects with any tendency to melanism. 



Boarmia repxindata was very common in the Arras woods and 

 the Foret de Nieppe, but again there were no meianic or other 

 atypical forms. 



B. consortaria occurs at Fruges. 



The Hepialids were nearly as infrequent as in 1916, though 

 H. lupidinus and H. hectns were not uncommon in many places. 

 Of H. humidi I saw only two ppecimens, one at Fruges and one 

 at Kemmel, though I often went dusking, and must have seen it 

 if it had been at all common. 



It will be noticed that with one exception (Z). compta) all 

 my macro-lepidoptera might have been taken in Britain. The 

 relative predominance of the Nolidge and Lithosiidae in the list, 

 and the relative scarcity, or even absence, of some of the 

 commonest British genera and species, are probabl}' the result 

 of chance. Such a condition of things is usual in two seasons of 

 haphazard work in any district when no insect has been specially 

 searched for.

NOTES AND OBSEEVATIONS. 

 Rhopaloceba at Marlborough in 1917. — In the following notes 

 of the remarkable season I have just spent in the Marlborough 

 country I have included the observations of some energetic 

 members of the College Natural History Society, especially Messrs. 

 Greenham, Lowe, and Paton. In every case, except CoUas 

 edusa, I have seen and verified the insects recorded. Hibernated 

 Aglais urticcs were veiy abundant, with a sprinkling of Vanessa io, 

 at the end of April, and later the larvge of both species abounded 

 on the nettles. Both broods of the former swarmed everywhere, 

 and the latter was common in August. Thanks to magnificent 

 ■weather in May insects were well up to date, Euchloe cardaviines 

 appeared by May 8th, and Callophrys ruhi in fair numbers from
