Streak).—The Green Hair Streak I have only found at Orton, and 
on that part of the moss near to Little Orton; they are on the 
wing in May, and can be taken until the end of June. I have 
taken the Purple Hair Streak at Thurstonfield, Orton, Newby- 
Cross, Dalston Hall and Newbiggin woods. The best mode of 
taking them is by beating the branches of the oak trees. The pupz 
can be obtained by digging at the roots of the oak trees in the first 
and second week in July; they are short and stout, of a bright 
shining brown colour. They are on the wing from the end of July 
till the end of August. 
Polyommatus Phlaeas (Small Copper).—This is one of the 
commonest species we have here abouts, and I have found it in 
every locality in which I have collected ; it is very fond of settling 
down on a heap of stones, or on the bare ground. These butter- 
flies are on the wing from April to September. 
Lycaena Alexis (Common Blue), Lycaena Alsus (Small Blue).— 
The former is very plentiful on Kingmoor and all common grounds. 
The Smaller Blue I have found on the railway slopes near 
Wreay, at Coweran Cut near Howmill, and on the banks of the 
Eden near Warwick Hall. Both species are on the wing from the 
end of May to the end of July, and I think we have two broods of 
the common Blues. 
Thanaos Tages (Dingy Skipper).—This is a very common 
species, and it occurs in large numbers on Kingmoor and Tod- 
hills, at Orton, Newby Cross, and Newbiggin. On the wing from 
May till the end of August. 
Hesperia Sylvanus (Large Skipper), Hesperia Comma (Spotted 
Skipper.)—Both of these I have taken at Thurstonfield, Orton, 
and Newby Cross. They are the most active of butterflies on the 
wing, and more resemble some of our moths flying from flower to 
flower; and when a wind is blowing, one’s eye can scarcely follow 
them. The Large Skipper is on the wing from the end of May 
till the end of July. The Spotted Skipper is the most rare here, 
and is soonest found amongst a few Oak trees that grow on the 
west side of the wood at Newby Cross ; it is on the wing from the 
middle of July to the end of August.
