lychnitis, coiiiinon on mulleins. Macrixjlossa j'licifoniiis, on honeysuckle, 

 pupated August 23r(l, turning at once, on u former occasion a larva of 

 this species remained under its web for a month before changing. 

 Choerocauijui clpt'iinr, a full-fed larva taken on "willowherb, August 

 24th (though plentiful at rhododendrons last year, the imagines were 

 not observed this season). Snierintluta })o])iili and Sjiln'u.r li(jnstri were 

 also taken ; of Anarta myrtiUi, throughout the summer there appears to 

 be a succession of broods; Fj/i/aera {('lostera) ctirtiila, several on 

 aspen ; Xotodonta carmelita, on birch, full-fed July 8th ; PlaUipteryx 

 falcataria, and 1'. larcrtula, July 9th ; < 'i/iiiatojihnrci tiovivomh, 

 common ; Acronicta h'jioritm, took a larva from sallow, September, 

 at Comrie, Perthshire, of an unusual colour, /■/:., the long hairs and body 

 of a bright canary yellow'', unfortunately this caterpillar perished. —

Eggs of Lyc.enids. — Erratum. — In the illustrations of Lycaniid 

 eggs {Knt. Ileconl, vol. xii., pi. xi., figures 4 and 6), the names Pol i/oui- 

 matit.'i icanis and y<>)iu'acJt's soiiiari/Kn should be reversed. As references 

 to these may be made in future it would be well, to make the correc- 

 tion on the plate as well as in the " explanation of plate" at end of

COLIAS HYALK AND C. EDUSA NEAR CrOYDON TX 1900. It will not 



be exactly news to readers of the T!i'corJ to be informed that both these 

 species were moderately abundant in this district throughout August 

 last. I have, however, noticed one or two points in connection with 

 the species which may be of some general interest. I may mention in 

 passing that my son, who had holidays from school, and myself, by 

 fairly hard work managed to net, between us, 65 Colias hyale, the 

 majority of which fell to the "junior net," behaving more time at his dis- 

 posal than I could spare. They were distributed in suitable spots all over 

 the district — Boxhill, Riddlesdown, Oxted, and Addington all producing 

 their quota of specimens. The flowery down-sides were much more 

 prolific than the clover or lucerne fields, but even these did not produce 

 abundantly, and it was curious to note how soon all the specimens 

 in a locality were caught ; one would perhaps net six or eight in the 

 first hour, whereas by staying on the spot afterwards all day, not more 

 than another would be caught, whilst by going on to a spot, perhaps 

 a mile away, another half dozen specimens would be the result. I 

 had never in my quarter of a century of collecting seen ( '. Jiyale until 

 this year, and could not understand why it should, on the occasion of 

 its visits to our shores, limit itself almost entirely to our south- 

 eastern counties, whilst its congener, C. nhisa, distributed itself more 

 or less over the three kingdoms. I think I know now ! ]\Iost men 

 who have chased a ( '. cditsa have a pretty fair idea what that means ; 

 I remember well my hrst ('. cdusa cliase. It was in June, 1877, I was 

 walking meditatively across a large field with a net in my hand. 

 Suddenly there floated across my vision a splendid yellow butterfly ; 

 I was in my teens then, and a bit of a sprinter, and I thought I could 

 run that butterfly down ; we started fairly even, and finished with the 

 butterfly about 250 yards ahead. I have always fancied since that 

 ('. hyalf flew at about this rate, but now know there is no 30 miles an
