near Steyning. HepioXm lupulina. — June 1st, a J netted flying about 

 in the sunshine on the Downs, near Clapham. Miltochrista miniata. — 

 August 7ch, a $ , in fine condition, on a paling at Broadwater. 

 Lithosia sororcula. — May 26th, a 5 clinging to a grass stem, in an oak 

 wood near Patching. Diacrisia sanio. — June 17th. Several $ s 

 " walked up " on the Downs near Steyning, Lancing, and Sompting. 

 Arctia villica. — May 33 st. Odd specimens found at Steyning and 

 Angmering, one, a ? , was netted flying along a lane in the daytime. 

 Malacosoma neustria. — A few nests of larvae noticed in the hedges 

 near Goring and Sompting. Macrothylacia rubi. — June 3rd. One $ 

 netted and a number observed flying on the Downs near Steyning, 

 Sompting, and Sullington, and found in the larval stage near Lancing. 

 Gosmotricke potatoria. — On June 17th, near Lancing, I found a cocoon, 

 high up on a grass stem in a meadow, looking very huge and con- 

 spicuous in comparison with the smaller cocoons of Z. filipendulae, 

 which were abundant all around. A $ emerged on July 7th. Drepana 

 falcataria. — May 26th, beaten out of birch near Patching. D. 

 lacertinaria. — I found a nearly full-grown larva on birch near Storring- 

 ton, on June 15th, from which I bred a ? on July 11th, a rather 

 interesting specimen as it is plain ochreous brown without any trace 

 of the usual dark frecklings. Acronicta leporina. — A full-fed larva 

 found on August 17th near Storrington on birch. It changed colour 

 and entered a piece of wood for pupation on the following day. Ayrotis 

 ypsilon. — August 10th, at Worthing. A. strigula. — July 16th, a few 

 disturbed from heather near Storrington. Mamestra persicariae. —J une

 daytime, resting on wild carrot blossom, while searching for Spilodes 

 palealis. Cucttllia chamomillae. — Two nearly full-grown larvae on 

 Anthemis, near Sompting. Pliisia gamma. — During the spring and the 

 early part of the summer a great many were seen, probably immigrants 

 from the continent. The new brood was met with from July 3rd in 

 astonishing numbers, in fact I cannot remember having seen this 

 species more abundant. Acontia luctuosa.—^On June 17th, a dull day, 

 I netted a fine S which I had disturbed from the herbage in a chalk 

 pit near Lancing. A careful search on this and following days 

 amongst the Convolvulus arvensis resulted in no more specimens. Bryo- 

 phila perla. — July 3rd. Apparently not common in the district, a dozen 

 or so only observed in the town at Worthing and Broadwater. 

 Prothynmia viridaria. — First brood, June 8th; second brood, July 24th. 

 Found sparingly on the Downs near Burpham, Steyning, Lancing, 

 and Edburton. As usual, specimens of the second emergence were 

 considerably the larger. Anarta myrtilli. — August 17th, although a 

 dull day, several were seen flying about the heather near Storrington.
