90 f September. 



During last month, I iownd Actaon in some abundance on rough broken ground 

 on the slopes of tlie cliffs about 15 or 16 miles east* of Lulworth Cove. 



The species was sparingly distributed over an extent of ground about three- 

 quarters of a mile in length ; but in one or two spots it was abundant. 



The loeality in which I found Actcson in the greatest plenty, consisted of a level 

 plateau about 300 feet in leugtli and 50 in breadth, apparently formed by a landslip 

 at no very remote period, on the side of the cliff at a height of about 130 feet above 

 the sea. The ground at this spot is extremely rough, with masses of rock lying 

 about in all directions, and from its proximity to the edge of the cliff and the fre- 

 quency of land slips, both from above and below, the pleasure of collecting on it is 

 certainly attended with that " spice of danger" alluded to by Mr. Birchall at p. 69 

 of the present vohime. 



The vegetation of this locality is of a very varied character, and includes, in 

 addition to several species of coarse grass and reeds, Equisetum Jluviatlle, Ruhia 

 peregrina, Teucrium scorodonia, Galium verum and mollugo, Picris hieracioides, 

 Agrimonia eupatoria, Artemisia vulgaris, Trifolium procunibens, Lotus corniculatus , 

 Hippocrepis comosa, Erythroea centauriuin, Tormentilla reptans, Vicia sepium, 

 Ononis arvensis, Orchis pyramidalis, &o. 



If Calamagrostis epigeios be the only food plant of this species, it must of 

 course occur in this locality, but I was not sufficiently well acquainted with the reed- 

 maces to be able to recognise it on the spot, and I have not subsequently been able 

 to identify it in the collection of grasses, reeds, &c., which I brought away from the 

 locality. 



I first met with Actceon on the 12th July, and altliough the majority of the 

 specimens were in fine condition, some of them were, even at this early date, much 

 wasted. On the 19th July, the last day on which I visited the locality, the males 

 were to the females in the proportion of 4 to 1, which showed that the species was 

 not then fully out. 



I was particularly anxious to secure eggs of ActcBon, but although I watched 

 hundreds of specimens, I was unable to detect a female in the act of oviposition. 



ActcBon appeared particularly fond of the flowers of Ononis arvensis (rest- 

 harrow), on which they constantly settled, but I rarely saw them alight on any other 

 flowers. 



Amongst other species of Lepidoptera which I noticed in this locality, I may 

 mention Colias Edusa (much commoner than I ever before saw it in July), Arge 

 Qalathea (abundant) , P. ^Zea;««, T. Tages, S. linea &nd Sylvanus, Z.jilipendulce and 

 trifolii, and E. bipunctata. — H. Goss, The Avenue, Surbiton Hill, Surrey : 1*^

Acronycta alni. — I joined the Annual Excursion of the South-London Ento- 

 mological Society to Three Bridges (for Tilgate Forest), on Monday, August 6th, and 

 spent a few hours in the Forest. A small Acronycta larva, beaten off birch, fell into 

 my net. It resembled, when at rest, the dropping of a bird, the anal segments being 

 of a dirty white colour, and the anterior segments blackish, with whitish markings. 

 The larva was quite unknown to us all, and though I felt disposed to think it might 

 possibly belong to alni, simply from the fact that it resembled none of the commoner 



* The Burning Cliff is a few miles to tM weet of Lulworth Cove.
