large ants, which were found in Mr. Fraser’s saw-yard in St. 
Martin’s at Palace, Norwich. These were found in some birch 
timber, from St. John’s, New Brunswick, and have been indentified 
for me bj r Mr. F. Smith, as the true Formica, lierculanea Li line, 
hut not that of Stephens and other English writers ; this I believe 
is the first time they have been taken alive in England. The 
female of this species contrary to what takes place in our native 
ants, retains its wings. It would he interesting to find, that this 
fine species had settled itself in this country, if it did do so, 
it would not he the first introduced species. I believe the little 
yellow pest, that frequents some of the houses in London, is 
an American importation ; Madeira has also given us another 
species. As a whole April was dull, cold, and ‘wet. 
Cold weather with strong N.E. winds prevailed during the next 
month. June also was very unfavourable on account of the want 
of sunshine and the coldness of the winds : during this month I 
took literally nothing. A change came in the middle of July, and 
we had some splendid weather for these insects, hut unfortunately 
I could not spare time to go after them ; though in the little time 
I had, I succeeded in taking some very good things. At Worstead 
on the 11th, I took off the flowers of Knavtia arvensis, a male and 
female of our finest Andrena, “ liattorfiana ” ; the weather was 
warm but dull, or I might perhaps have taken more of them. A 
day or two later I found three females of that handsome parasite 
Nomada armata, flying about a bank at Eaton, at nine o’clock in 
the morning : as this parasite is believed to confine its attacks to 
Andrena liattorfiana, and this Andrena frequents the flowers of 
Knautia arvensis only, I hunted about for that plant, and suc- 
ceeded in finding a fine patch of it, from which I took half a 
dozen females of the latter bee, but could not find a male of 
either. 1 look upon these captures as very singular, for they were 
in a situation I had frequently hunted in past seasons, and yet I 
never saw a specimen of either till this year. I can hardly believe 
I could overlook such largo and conspicuous species ; if I did 
not, how came they there this year? One would almost think they 
must have been there before; but as I know the time of appearance 
and the locality, it remains to be seen if thej r can be found there 
next season. It is remarkable that an insect should be infested 
with a parasite, and that parasite extremely scarce, yet found on
