394 Mr Hardy on the Entomology of the Cheviots. 



May, and forwarded them to F. Smith, Esq., of the British 

 Museum, the hest authority on this branch of Entomology. 

 Mr Bold has already in the " Nat. Hist. Trans, of Northum- 

 berland and Durham" (1869), given a Catalogue of the 

 Aculeate Hymenoptera. The species near Wooler are fewer 

 than in the Newcastle district ; but there is one very numer- 

 ous on the hills which he has not enumerated. I give a list 

 of the whole. 



Formica fusca. Plentiful beneath stones by dry sandy road 

 sides, and in decayed trees. It swarms beneath rocks on the 

 face of the Sneer hill. The Aphides of grass roots sometimes 

 occur in the nests. 



,, nigra. In colonies less populous than the preceding, 

 beneath stones by the sides of Wooler water and in Langley- 

 ford vale. There were a number of dead Myrmica ruginodis 

 among them. 



,, flava. Not quite so numerous, Wooler haugh and 

 Whiteside hill. The Aphides of grass roots are frequent in 

 their resorts. 



,, umbrata. Numerous beneath stones on the Sneer hill, 

 and in Langleyford vale. Larger and duskier than the last. 

 New. 

 Myrmica ruginodis. The commonest of the red huedants. It 

 ascends the apex of Cheviot and Hedgehope. Astilbus canali- 

 culatus appeared in one of the nests. 



,, scabrinodis. Along with the last, beneath stones, 

 sides of Wooler water above Earle Mill, and above Care burn 

 bridge. A brighter tinted insect than the last. 



Obs. I have not seen If. Icevinodis here, which Mr Bold says 

 is the most abundant kind in the Newcastle district. 

 Leptothorax acervorum. A minute, shining ant, found in 

 only one decayed alder stump, at Langleyford Backwood. Mr 

 Bold met with it in trees at Gosforth ; and the collectors at 

 Loch Kannoch found it in great abundance in decayed fir 

 stumps. Mr Smith remarks : " This is the old Myrmica 

 acervorum ; the genus Myrmica being now divided into numer- 

 ous genera, founded principally upon the varied number of 

 joints in the palpi" 



ARACHNIDA. 

 Only a few Spiders have been added to the list this season. 

 The number of specimens collected -was also limited. The 

 following are new to the distriet. 



Lycos a allodroma. I have obtained this twice among the 

 gravel of Wooler water, above Earle Mill; it occurs near 

 Gibside, county of Durham, in the gravel of the Derwent.
