base of the wing nearly to its apex ; the distribution of fulvous 
and black on the remainder of the wing is clearly indicated 
in the figure, from which it will immediately be seen that 
black greatly predominates; the basal portion of the wing is 
iridescent fulvous, and the colour extends along the inner 
margin to the anal angle; on the hind wing the disk is 
almost entirely black, the inner margin being tinged with 
fulvous iridescence, and the hind margin having a double 
series of fulvous lunules. On the under side the central 
portion of the fore wing is almost entirely black; the hind 
wings have five silver spots about the base, but none on other 
parts of the wing; the median diagonal series of silver spots 
is entirely absent, but their position is indicated by a series 
of obscure markings.—Hdward Newman.

II. BARK-GALLS. 
THE three species next to be described are generally found 
more or less covered with earth, moss, or dead leaves, on the 
lowest parts of the stem, or on shoots growing out of the 
ground; others only occur on that portion of last year’s 
shoots which is above the ground: they are almost invariably 
in clusters, and in two instances are perceptible only from the 
unevenness of the bark or the incrassation of the twig. 
Fig. 3. Aphilothrix Corticis.—Of this rare gall I 
: have seen only a few clustered specimens. It 
is of an obconical form, and swells about 
seven or nine millemetres above the surface 
of the bark of old oak-stems (probably of 
Quercus sessiliflora or Q. pedunculata). The 
aperture at the apex is from three and a half 
to five millemetres in diameter; more than 
half of the gall is sunk in the bark, which 
seems to form a wall round it. It is hard, of 
a brown colour, and somewhat cylindrical

below the summit, is a convex septum,—thin, hard, and of
