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 summer of 1871. 
The middle specimen is also a light variety of the insect; but 
its greatest peculiarity is the = 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 Stevens; “Loanda,” Beulah

—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 
galls, 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 peduncle, and 
has at the opposite end a saucer- 
shaped depression, with up-turned 
edges and a small wart in the 
A. urnrormts (and in section). centre. In section the gall exhibits
