variety, and is so very dissimilar from the type form that I 

 need not describe the difference: the figure itself is, if any- 

 thing, rather too dark, otherwise most beautifully represented ; 

 the under side is very light and remarkable : this specimen 

 was taken on the south coast of Wales in the sunnner of 1871. 

 The middle specimen is also a light variety of the insect; but 

 its greatest peculiarity is the is mark placed sideways on the 

 superior wings, and the form of the dark, somewhat triangular 

 patch near the upper edge : this is a specimen I have had for 

 some years, and was taken in Devonshire. The last, which 

 is a very dark form of the insect, was captured near Dover 

 three years ago : the white spots are mostly wanting round 

 the superior, and partly round the inferior, wings. All the 

 specimens are males. — Samuel Sievens; ^''Loanda," Bealali

 — From July to late in the autumn 

 we frequently meet with leaves of 

 bushy Quercus pubescens, the upper 

 sides of which are either turned 

 down or partly rolled up, and more 

 or less twisted and folded. On open- 

 ing the leaf we find on the middle 

 rib, at the point where it is thickest 

 and most tightly rolled, a row of 

 small, hard, barrel-shaped or oviform 

 galkii, of about the size of hemp- 

 seeds, at first green, then of a rosy 

 or reddish brown colour, with lon- 

 gitudinal striations. The gall is 

 generally firmly attached to the 

 midrib by a short ])eduncle, and 

 has at the opposite end a saucer- 

 shaped depression, with up-turned 

 edges and a small wart in the 

 A. rp.N.'ErnnMis (and iu section), centre. In section the gall exhibits
