THE YOUNG NATURALIST. 



[August 



ment Iris had disappeared over the tops of the trees. It was disap- 

 pointing certainly, but even to see the monach of the woods alive is 

 not the lot of every entomologist. I had to cool down, but it was 

 hard after that to content myself with A. euphvosyne, S. malvce, N. 

 liLcina, P. phlams, a few V. macidata, and C. lichenaria. — D. H. Stewart, 

 Radley. 



Ccenonympha davus. — On Wednesday, July 16th, I had the 

 pleasure of seeing this insect in its natural habitat for the first time. 

 Guided by Mr. Finlay of Meldon, who is intimately acquainted with 

 the locality, I made my way to Greenleighton Moors, Northumberland, 

 not far from the Simonside Hills. Though called a moor, it is really 

 a bog — not quite so wet in some places as in others, but always wet. 

 On the dryer parts Myrica gale was growing among the ling and heather 

 and there we took Tovtrix viburnana. Where it was wetter, Bog 

 Asphodel was flowering, and the Sundew (Drosera rotundifolia) just 

 coming into flower, was abundant. The day was not very favourable, 

 only giving us glimpses of sun, but at every glint Davus flew. Not in 

 great numbers, but apparently spread all over the moor, and most 

 abundant in the wetter places. I found it impossible to run on the bog, 

 it was so necessary to step on the tufts of ling or heather, but they did 

 not fly far, and in about an hour we had secured nearly 50 between 

 us. About 1 a.m. Myvtilli began to fly, also M. schuhiana, but the sky 

 now clouded over and it began to rain. We were loth to leave, and took 

 two E nanata in very fine condition while it was raining, but there 

 seemed no prospect of it clearing, our nets as well as our clothes were 

 soaked, and we compelled to make the best of our way to the Railway 

 Station. — John E. Robson, Hartlepool. 



Hepialus Humuli.— On June 19th, I was watching the flight of a 

 $ Humuli in hope of seeing the $ fly towards it. While it was 

 swinging backwards and forwards in the usual style I saw a second $ 

 approach it, and fly so close beside it that they occasionally came in con- 

 tact. A third then joined them, and afterwards a fourth, though be- 

 fore the last one appeared I had observed that they were really at play, 

 flying about each other as the house fly does at our curtain fringes, 

 coming in contact with each other in the same way, and flying off 

 again, sometimes two were in contact, sometimes three and very rarely 

 all four. I watched them a considerable time, then netted three of 

 them at one stroke. I released them almost immediately and to my
