l64 THE SCOTTISH NATURALIST 



Subfamily Chaitopiiorin/E. 



Genus Chaitophorus, Koch. 



Chaitophorus aceris, Linn. Apterous viviparous females and 

 young were abundant on the under-surface of the leaves of syca- 

 more at Stirkoke, Wick, on the 7th September, 



Subfamily Lachnin^. 



Mr H. F. Wilson has kindly identified the following species of 

 Lachninae. I collected them in various localities in England and 

 Scotland, principally in the summer of 191 7. 



Genus Lachmis, Burmeister. 



Lachnus costata, Zett. =Z. fasciatus, Burmeister. I took 

 apterous viviparous females, larvre, and one alate female on spruce- 

 fir {Picea excelsa), at Wye, Kent, on nth July 1917. I also found 

 it abundantly at Crowborough on 26th May 1918. On the 

 5th October 191 7 brown apterous females and brown larvae, together 

 with pale green larvae and nymph.x, were abundant on a spruce-fir 

 tree at Beauly, Inverness-shire. The pale green larvs matured to 

 nymphae, and the latter emerged in a few days as winged males. 



Genus Lachftiella, Del Guercio. 



Lachniella ciiicica, Del Guercio. Apterous viviparous females 

 and larvae were common on the bark of the older branches of silver 

 fir {Abies pectinata) at Rothes, Morayshire, on 26th September 191 7. 

 I took this species also at Beauly, Inverness-shire. 



Lachniella juniperi, F. I found apterous females and larvae on 

 juniper at Wye, Kent, on ist July 191 7. I also observed this 

 species at Swordale, Evanton, from the end of July to the beginning 

 of October, but I noticed no winged specimens. 



Zachtiiella laricis, Walker. Apterous and alate viviparous 

 females and young occurred on a young larch-tree at Wye, Kent, 

 on 28th June 191 7. It was also abundant on the branches of old 

 larch-trees at Swordale, Evanton, in the end of July, and I found it 

 at Rothes, Morayshire, in the end of September. 



Lachfiiella pichtce, Mordwilko. Alate and apterous viviparous 

 females, larvae, and nymphte occurred sparingly on silver fir {Al>ies 

 pectifiata) at Rothes, Morayshire, in the end of September 191 7. 

 They were to be found solitarily on the terminal shoots, resting in a 

 slanting position at the base of the needles, with proboscis inserted 

 in the stem. Their colour harmonised well with their surroundings, 

 the deep, dark green of their back being of the same shade as the
