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. — Edward 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. Aphilotlirix Corticis. — Of this rare gall I 



^^ have seen only a ievr clustered specimens. It 



/^^^^ is of an obconical form, and swells about 



flsjp^^ seven or nine milleraetres above the surface

; Quercus sessiUflora or Q. pedunculata). The 



^^ apertui-je at the apex is fiom three and a half 



^^^^^ to five millemetres in diameter; more than 



g^^y half of the gall is sunk in the bark, which

opening is sharply defined and nearly circular; within the 



opening, and about a niilleraetre or a raillemetre and a half
