THE ENTOMOLOGIST. 161 



Drepamilce. — P. Lacerliila and Falcula, with C. spinula, 

 represented this small family. 



NocliKB. — The season for Xoctuae had scarcely arrived, and 

 the hot, dry, calm nights, were not propitious for sugar, so 

 that my captures were not numerous. T. Batis, A. Aceris, 

 C. Or, C. Duplaris, a very fine var. of G. Trilinea, and a 

 few very common species, were all I observed. 



Pyrales. — E. octomaculalis, A. nemoralis, Pandalis, Lan- 

 cealis and Fuscalis, with several common species, complete 

 ray captures ; and, for so short a stay, show that East Sussex 

 is a good entomological locality.

Migration of Bulterjlies. — June 4th. This morning very 

 large numbers of white butterflies — of two species, Pieris 

 Brassicaj and P. Rapa?, the latter, however, greatly pre- 

 dominating — came into the North Lincolnshire marshes from 

 the Yorkshire coast of the Humber (which, opposite this 

 point, is from four and a half to five miles across). For an 

 hour that I was near the sea embankment they were con- 

 stantly passing inland, flying, too, against a rather stiff 

 south-west breeze. Looking towards the centre of the river 

 with a strong glass I could distinguish flights of them far 

 away, flickering in the blaze of sunlight, against the gray 

 background of water, like falling snow-flakes. I remember a 

 very similar immigration of white butterflies into these 

 marshes in the dry summer of 1870. — John Co r clean .v ;

Pyrarga Egeria (Entom vii. 129). — There is a plantation a 

 little distance from this town where, amongst many other 

 things both rare and common, Pyrarga Egeria may be met 

 with in some abundance, and, contrary to the experience of 

 your correspondent Mr. Harwood, the insect seems of late to 

 have increased in numbers in this particular locality. In 

 fact, I have always regarded it as one of the common species, 

 and have seldom taken the trouble to procure any. In some 

 pasture-land adjoining the wood, Melituea Artemis was at one 

 time to be found in great prolusion ; but for the last two or
