Oculea, Xanlhographa, Suffusa, &c,, swarmed at all the trees; 

 also Trapezina in every possible variety, from nearly white 

 to dark mahogany-colour. Acosmetia Caliginosa we ob- 

 tained pretty freely by sweeping the long grass in damp 

 woods : most of the specimens were more or less damaged : 

 we are indebted to Mr. S. J. Capper and Mr. A. Owen for 

 furnishing us with the exact locality of this insect ; also to 

 Mr. J. Gerrard, of Lyndhurst, for much valuable information 

 respecting the Forest. The above were captured within a 

 radius of about sixteen miles. Among other insects of 

 various kinds, brought to us by small boys, &c., were speci- 

 mens of Halias Quercana, Bajtdaria, Exlersaria, &c., and of 

 course Caja and B. Quercus, in various stages of mutilation, 

 from white to perfectly transparent wings. At the com- 

 mencement of the season insects were out very early : Thecla 

 Rubi and Polyommatus Argiolus were quite over before the 

 end of April. Later in the season the case was different : we 

 found Pieris Crata^gi in splendid condition the last week in 

 July, which is, we think, unusually late for this species. —

Mr. Dunning exhibited a specimen of the common Ce- 

 tonia aurata, found in a garden at New Cross on the 1 1th 

 April : it was partly covered with earth, and appeared to 

 have just emerged from its underground hybernaculuu), 

 whence it had been prematurely tempted by the first warmth 

 of spring. 



Mr. Frederick Smith exhibited both sexes of Cynips, the 

 male of which had at last been detected by Mr. Walsh in 

 America. The oak-apples on the black-oak (Quercus tinc- 

 toria) are first observed in May, and reach their full growth 

 in a few weeks; by the middle of June male and female gall- 

 flies (Cynips quercus spongifica, Osten-Sacken) emerge from 

 a small proportion of them, say one-fourth ; the remaining 

 three-fourths do not develop flies until the autumn, and then 

 produce gall-flies (C. q. aciculata) closely allied to, yet quite 

 distinct from, those produced in June, and out of thousands
