somewhat inconstant in the variable and common O. parietum. 
There is no specimen of the true O. parietinwm in the National 
Collection, but Curtis’s figure is, as usual, very fine. Illiger was 
the first who clearly differentiated the two Linnean species, but 
Wesmael reunited them in his monograph (Mon. Odyn. Belg., 
p- 24, and Supp., p. 6). The O. parietinwm of Fabricius, Schrank, 
or Panzer is not this species—HEpwarp A. Fircn; Maldon, 
Essex, August, 1879. 
THe Guowworm.—Near midnight, the 8th of October, my 
neighbour, Mr. Johns, of St. Marychurch, travelling between 
Cherston and Dartmouth, in Devon, when about a mile from the 
former place, observed four glowworms shining brightly in the 
grass by the roadside, and brought one of them, alive and active, 
to me the next day. Mr. Knapp, in his pleasant ‘Journal of a 
Naturalist,’ says that glowworms can hardly be said to shine after 
the middle of July, except that he has ‘‘ repeatedly noticed, deep 
in the herbage, a faint evanescent light proceeding from them, 
even as late as August and September.” And then he describes 
one particular occasion, a warm, dewy evening, September 28th, 
1826, when he saw multitudes of evanescent sparks in the grass. 
But “instead of the permanent green glow that illumines all the 
blades of the surrounding herbage, it was a pale transient spot, 
visible for a moment or two, and then so speedily hidden that we 
were obliged, in order to capture the creature, to employ the light 
of a candle.” (Op. cit., p. 803). But the fact I am now com- 
municating occurred even much later in the season than this; and 
the display of light was not to be distinguished from its summer 
brightness.—P. H. Gosse; Sandhurst, Torquay. 
MycETorpHaGus QuapricuTratus, Mull.—From the numerous 
enquiries I have received for this insect it would appear to be by 
no means common. I find it fairly plentiful in spring and 
autumn in a feeding-bin in one of my cow-sheds. This bin is 
nothing more nor less than a narrow portion of the shed fenced 
off, and filled about half full of clay, firmly rammed down. A 
few old boards are placed on the clay, and it is attached to, and 
in the dust and seeds beneath these boards, that I find the beetle. 
It would seem that the grand secret of the beetle’s presence lies 
with the boards, for I have been unable to find it in any bin
