170 Mr. Hardy on the Entomology of the Cheviot Hills. 



that tree. This is now recorded for the first time, for the N. 

 of England. Many examples. Broadstruther wood, woods 

 about Langlee, and on the Lill Burn. 

 Philhydrtts nigricans. Cold Martin Moss. 



,, MARGINELLTJS. Ditto. 



Cis Boleti and 0. eestivus. The first in Polyporus versicolor ; 

 the second in that fungus, and P. vulgaris also. Broadstruther 

 wood ; Lill Burn. 



Octotemntts glabkiculus. With the preceding. 



Orchesia micans. Corky fungus of the Alder {Polyporus racliatus) ; 

 scattered and not numerous. Broadstruther wood ; woods 

 near Langlee ; woods on the Lill Burn. The last is the locality 

 where I first obtained the fungi, from which I bred it. The 

 rarer Carida Jlexuosa, which I then observed, did not occur on 

 this occasion. 0. micans jumps like a fiea (" citissime saliens ") ; 

 but I remarked that as soon as it concealed itself under a frag- 

 ment of the fungus, which had to be cut or crushed to pieces, 

 it became quiet. 



Anas pis rtjficollis. I remarked numbers of this insect drowned 

 in fir rosin, on old tree stumps. 



Salpingus foveolattts. Mr. Bold remarks that this is new to 

 Northumberland ; and that another example occurs in Mr, 

 Boyd's collection. This was found about Langlee, in the Alder 

 woods. 



Melanotus eulvipes. Larva only in decayed Alder, near Langlee. 



Apion vorax. This lives on plants of the vetch kind, but at 

 Broadstruther I shook great numbers from a birch tree. I 

 once, at Lobley hill near Eavensworth, got numbers of it on 

 heather. 



Strophosomtjs Corylt, retustjs, and limbatus ; various localities. 



Graptodera longicollis, Allard. This is formed at the expense 

 of the old Haiti ca oleracea. From heath on Whiteside (or 

 Whitsunbank) Hill. The insects were only clustered on cer- 

 tain bushes of the heather, and there were more females than 

 males. If this disproportion of the sexes is general, may not 

 this be the reason for the gregariousness, which renders the 

 Halticee such pests ? They associate to pair, but at the same 

 time must feed, and in congregating eat up everything. I 

 observe that Haltiea Nemorum (the Turnip Fly), this summer, 

 after its destructive career was closed, has fixed itself on some 

 grown turnips, rather than others ; and that these " try sting " 

 plants (if such they are) are miserably defoliated ; the bulb 

 sometimes only left. The same congregation on certain choice 

 plants may be also remarked in the Thyamis of the Ragwort ; 

 and perhaps the most of the social Chrysomelidse. With 

 regard to G. longicollis, Mr. Langlands, of date August 4, 1870, 

 sent me a number of its larvae, which feed in bands on the
