Dr. Giraud. It is found either on the 
branches that are covered with earth or 
moss, or on the lowest part of the trunk of 
Quercus sessiliflora or of Q. pubescens. 
Like the two preceding galls it consists of 
an egg-shaped inner gall, which, with a 
covering as thin as paper, surrounds the 
large larva-cell, and is half a centimetre in 
length. The exterior surface, when dry, is 
covered with a thin, shining yellowish brown 
layer of bark. Out of this layer emanate , 
a great number of radiating outstretched 
threads, half a centimetre in length, and 
covered with scattered hairs, about one 
millemetre in length. Dr. Giraud found 
this gall late in the autumn; and the 
perfect insect emerged in the September 
of the following year.—G. L. Mayr.

Argynnis Niobe in Kent.—I beg to submit to your inspec- 
tion a male specimen of a fritillary, caught in company with 
Aglaia on a very hilly inaccessible spot near here. Would 
you kindly let me know your opinion of it? I have sent a 
male and female, also, to Mr. Doubleday. They seem to me 
to be out before Aglaia, as Aglaia, specimens of which I have 
a hundred or more caught to-day, are bright and fresh. Are 
these varieties, or another species? Shall be happy to 
furnish the locality —W. Wigan ; 8, Wincheap, Canterbury. 
[Mr. Doubleday allows me to publish the following 
information :—“I yesterday received from a Mr. Wigan a 
pair of Argynnis Niobe, which he says he caught on some 
hills near Wye, in Kent, flying with Aglaia, of which he took 
more than a hundred specimens. He states that he took 
three male Niobe on Monday, two of them being much 
wasted, and a female on Tuesday; this he sent to me, 
together with the best male; this was dead, but not stiff, and 
the female was still alive: they are not much more than half 
the size of my continental specimens, being very little larger
