MR. T. J. BOLD ON LOCAL HOMOPTERA. 129 



6. P. spumarius, Lin. Exceedingly abundant everywhere, 



and very variable in colour. This creature is certainly 

 the most abundant of all our insects. Every plant is 

 covered by the frothy secretions of its larva, and the per- 

 fect insect may be seen, in hundreds, seated upon the taller 

 plants, preferring thistles. 



7. Apliropliora Aim, Lin. A large conspicuous species, found 



in woods, mostly affecting the birch, and far from rare. 



8. Tettigonia viridis, Lin. Both sexes of this very pretty in- 



sect have been taken at Boldon Flats, where it is some- 

 what abundant, frequenting low herbage near the water ; 

 indeed, it is often found on plants growing in water. 



9. Euacanthus interuptus, Lin. A common and widely dis- 



persed species, frequenting herbage. I once found it in 

 immense abundance on the hound' s-tongue (Cynoglossum 

 officinale) at Cambois. 



10. Macropsis Lanio, Lin. On trees, common. Both sexes 



taken. 



11. Idiocerus Populi, Lin. Little Benton and elsewhere; fre- 



quents trees, and is not rare. 



12. Pediopsis fruticola, Fall. On trees; exceedingly common, 



and very variable in size, and still more so in colour ; 

 sometimes of very sober tints, and very often ornamented 

 by brightly contrasted colouring. 



18. Acocephalus rusticus, Fab. Abounds in grassy places, in 

 Northumberland, Durham, and Cumberland. The females 

 are especially abundant inland, more so than the males ; 

 but the latter sex are certainly the most abundant on the 

 sea-banks, especially in autumn. 



14. Ac. bifaciatus, Lin. Males only have been taken of this 

 pretty insect. I caught one specimen by sweeping her- 

 bage in Briar Dene, and two others on a moor in Cumber- 

 land, in June. *
