fresh, the leaves are pale, blotched, and when old, the greater part of 
the leaf looks dead and withered. These have not emerged yet, 
so I cannot say for certain which of the two species that mine 
the Birch it is, F. puviila or F. hetulte. They are said to appear in 
May and June, and again in the autumn. 1 took these mined 
leaves in June, but the imago did not emerge as I expected this 
autumn. Perhaps mine were too lato, and it may be the eggs laid 
by the early Hies that come to perfection in the autumn. 1 also 
recorded a female of Tenthredo obwleta, a rather common Sawfly, 
given to me by Mr. Atmore, taken at Lynn. This year I swept 
a great many females off the Ling on Mousehold in June. It is 
very singular I should never have met with it before, especially so, 
because at the time and place I was sweeping for an Ichneumon which 
I discovered there a few years before, and had named and described 
( Olypia truchanterata ), and which I could always find on the Ling 
in June, and often swept there for it. The larva of this Sawfly is 
unknown. I had hoped to have gone there later to try and find it, 
but forgot it. I hope to bo more successful next year. With these 
Sawflies I found two specimens of Mesoteius filicnrnir, and think 
it not improbable that they are parasitic on this Tenthredo. 
I think Mousehold will become a good hunting-ground for 
entomologists when the trees that have been planted grow to 
a good size. I wish Alders and Sallows would grow in the lower part, 
as these are favourites with many larvae. This place has a very great 
advantage over many other localities. You can go where you like, 
without being confronted with a black board bearing a notice 
in white letters that “ Trespassers will be prosecuted, by order ” of 
somebody or other. 
The early part of the year was very unproductive : there seemed 
to be no Hymenoptera about. Solitary Bees and Wasps were very 
scarce, in fact, so were all other divisions of the order. I often 
did not take half-a-dozen insects in an afternoon. Social Wasps 
seemed fairly abundant in the autumn, and towards the end of 
summer there seemed more insect life about, at least, of this 
order. 
At Earlham, on July 30th, I took two females of Heterogamm 
dirpar. Lev. T. A. Marshall, in his monograph of the Braconkke, 
says it is found in Fir woods in the autumn, but not common. 
These were taken quite five hundred yards from Mr. Ripley’s
