that the eggs hatch in the autumn. Having reared broods of P. flavocincta, several 

 times, the eggs of which always hatched in April, I thought it very improbable 

 that the eggs of such a closely allied species as nigrocincta should hatch in Septem- 

 ber ; I therefore wrote to Mr. Stainton, asking him to refer to Freyer's account of 

 the larva of this species and he most kindly sent me a translation of it, from which 

 it appears that the eggs hatch in April like those of all the other species of Polia. 

 This is confirmed by my friend M. Milliere. 



Freyer found the larva? rather difficult to rear, many of them dying when full- 

 grown. — Henry Doubleday, Epping, August 14th, 1869. 



Note on eggs of Lycmna Arion. — I think Mr. Dembski has mistaken the eggs of 

 some other insect for those of L. Arion : he says they are oblong and either white 

 or yellow like those of Anthocaris cardamines. The eggs of the Lyccenidce are 

 round, and very closely resemble those of the Notodontidce. I have never seen the 

 eggs of L. Arion, but my friend Mr. Buckler informs me that they are round, rathor 

 flattened on the top and palo blue, the colour of a hedge-sparrow's egg. I believe 

 the larvae of all the single-brooded species of Lycmna hybernate, and feed in the 

 spring till the end of May, when they assume the pupa state. — Id. 



Note on eggs of Lyccena Arion. — On the 15th June, 1869, 1 had the great pleasure 

 to receive from Mr. Herbert Marsden, a $ and $ Lycmna Arion, alive, captured by 

 him, together, and accompanied by two small plants of Thymus serpyllum in 

 blossom. 



These plants were potted separately, and the insects put on one of them under 

 a glass cylinder. During a gleam of sunshine, the ? certainly appeared to me to 

 deposit an egg amongst the flowers, but the weather being cold and cloudy, I 

 deferred further observation till the following day, when I again saw her deposit 

 an egg, as before. 



After dark I removed the butterflies to the second plant in order that I might 

 closely inspect the first on which they had been for two days ; nor was I dis- 

 appointed, for, on the morning of the 17th, on looking over the blossoms with a 

 strong lens, 1 detected six eggs, all laid on the calyces between the heads of flowers, 

 but not one on either stalk, stem, or leaf. 



The egg of Arion is round, smooth, and depressed on the top 5 pale greenish- 

 blue in colour. 



Although the eggs hatched both with Mr. Merrin and myself, yet wo have 

 failed to detect the young larvse on the plants at present ; but we believe they must 

 be very small, hiding away somewhere, and that they will most likely hybernate. 



I have wished to state what I have noted so far, hoping to resume my obser- 

 vations of this very interesting species on a future occasion. — Wit. Buckler, 

 Emsworth, August 13th, 1869. 



Notes on Solenobia pomonce and Xysmatodoma melanella. — It is now some ten 

 or twelve years siDce I met with a largo number of cases, which apparently 

 belonged to a species of Solenobia, on fruit and other trees in this neighbourhood. 

 When I first discovered the cases, I supposed them to be inconspicuella, which I 

 knew occurred round Bristol ; but, upon comparing cases of my insect with cases of
