ACORN- AND BUD-GALLS OF QUERCUS CERRIS. 201 



but on the higher shoot. They are deep green, with black 

 heads; and, through the plant being buried amongst larger 

 herbage, are very difficult to find. A few perfect insects 

 emerged early in August. They feed during the first and 

 second week in July. 



in July, 1877 and 1878, I first had the pleasure of finding 

 cones of Gracilaria populelorum on birch. At the former 

 date one insect was bred from a miscellaneous collection of 

 buds, mined leaves, &c. ; but this year, by observing the 

 different modes of feeding adopted by the larvae on the 

 birches, I succeeded in taking about three dozen cones, 

 vi^hich occupy an entire leaf, and inside which a green, 

 rather transparent larva was feeding. These larvae changed 

 to very long, taper, light green pupae, from which emerged, 

 in all, only five imagos of G. populelorum, and about 

 eighteen or twenty large ichneumons. This accounts for the 

 comparative rarity of the insect. 



Some years ago Mr. Hodgkinson bred a few Asycha pro- 

 fugellcB from seeds of gentian ; and, as he had afterwards 

 failed in another attempt, I tried other seeds, such as Pirnpi- 

 nella saxlfraga, wild carrot, &c. On September 29th these 

 were placed in a flower-pot, and exposed all winter; and to 

 my satisfaction, between July 1st and 30th about two dozen 

 imagos appeared, in company with the Tortrix, Setnasia 

 rii/illana, and CEcophoraJiavunaculella.

ACORN- AND BUD-GALLS OF QUERCUS CERRIS. 



By E. A. Ormerod, F.M.S. 



In the 'Entomologist' (P^ntom. x. 42) I drew attention to 

 some specimens of a minute bud-gall found in the previous 

 year on the "Turkey oak" {Quercus cerris), and its variety 

 the "Lucombe oak," at Kew : few in number and then 

 deserted, but of some interest to record as soon as secured, 

 as being the first-known instance of Cynipideous gall attack 

 to this species of oak in Britain. Since then, in the spring 

 of 1877, I found a few specimens of the gall with the insect 

 developing; but it was not till May 3rd of the present year 

 that 1 was able to secure sufficient specimens of the gall, with 

 the contained gall-maker, as to !^how it to be an Andricus, 

 but apparently of a species hitherto undescribed.
