permit of capture. I have another example, which Mr. Hislop 

 took in the west of Berwickshire. This fine insect is not 

 recorded in any of Mr. Bold's lists as Northumbrian, but may 

 occur in some of the older Newcastle collections. 



APHIDS. 



Siphojstophora Pelargonii, Kalt. On Mallows by the side of 

 the Brewery road, Wooler ; wingless and winged females. 



Phorodon Humtjli, Schrank. Most abundant on Sloe- thorn at 

 sides of the haugh Old Middleton wood. 



Aphis dilineata, Bucldon. On the Moss-rose in a garden at 

 Wooler, both the wingless and winged females. This is an 

 undescribed species, and is named from the double dorsal 

 green stripes. 



,, Padi, L. Abundant on the Bird Cherry in South 

 Middleton dean ; also in Middleton Hall lower wood, where it 

 also frequents the Viburnum Opulus, after deserting its first 

 food plant. 



,, Lychnidis, Z. Very abundant on Lychnis diuma, near 

 Caldgate Mill. 



Lachnus Jtjniperi, Fab. Very abundant on Junipers on the dry 

 Middleton banks, and still more so on those equally dry un 

 Iiderton moor, on the south side of the Lill-burn. There were 

 wingless and winged females present. Vast numbers of Ants 

 (Formica fusca ) attended some of the bushes, for sake of the 

 honey-dew. Others swarmed with Bibio Jolumnis, B. Marci, 

 and other species. Kaltenbach says he never found this 

 species on naked heights or exposed plains ; it usually affects 

 warm, damp places. This is quite contrary to my experience. 

 In Berwickshire, where it also occurs, the Junipers grow on 

 the driest banks, and are rarely sheltered. 



Trama eormicaria, Kalt. In ant's nests at the root of BTolcus 

 mollis at the side of a ditch, in a bog near Newton Tor ; again 

 at the roots of Anthoxanthum odoratum and Carex dioica, at the 

 base of Watch Law ; along with Formica umbrata ; and very 

 abundant in nests of Formica fusca, at the roots of Festuca, in 

 a plantation on Whiteside Hill. I believe there is another 

 white species along with it at Watch Law, but the specimens 

 were too juvenile. The ants usually scamper off and leave the 

 Aphides to their fate, especially the fusca. The umbrata several 

 times laid hold of them to transport them out of view, as it 

 would do to its own cocoons. The open spaces in the runs of 

 the ants permit freedom to the Aphids to multiply, and to pro- 

 cure its food most readily. The ants and Aphids are associated 

 on terms of mutual accommodation. 



,, radicis, Kalt. This is a white somewhat globular Aphis, 

 surrounded with much cottony exudation. Mr. Buckton, who 

 examined it, says, " it has a long proboscis, but not so long as
