the coxa; of the third pair of legs ; the second joint is short 

 and broad with two fine short hairs towards the distal end; the third 

 joint is slightly longer than the second, and furnished with 

 five pairs of fine short hairs. The tip of this joint is very dark. 

 The waxgland plates are situated on the five posterior segments of 

 the abdomen, in pairs on either side of the median line, excepting 

 on the last segment where there is on each side only one long 

 plate. The plates are variable in size and shape. Each plate has a 

 double contour ; the inner portion consists of a great number 

 of more or less spherical cells which are arranged in radiating lines 

 these usually converge towards the centre, but occasionally towards 

 one corner of the wax plate. The inner contour of each plate 

 is conspicuously marked by a dark line ; the outer contour is formed 

 by the outer edges of a row of elongated cells which are arranged 

 side by side. These cells are usually larger and of a different shape 

 from those in the centre of the wax plate. The legs have 

 the tibise furnished with a few hairs at the apex; the tarsi also 

 bear a good many hairs throughout their length. Length, ii mm. 



Foodphint. Unknown. 



Locality. Swordale, Evanton, Ross-shire. 



Notes. I found three of these aphides whilst digging in a flower- 

 bed in our garden on 22nd October. My attention was attracted 

 to a small lump of soil that was covered with a whitish powder: on 

 examining it I found these aphides in it surrounded by flaky white 

 wool. I could not discover any root associated with them, and 

 though I searched carefully for more in the same place none were 

 to be seen. The plants in the immediate neighbourhood were 

 roses, daffodils, azalia, etc., and weeds such as grass and 

 buttercup {Ranunculus) were plentiful. For the recognition of 

 this as a new species I am again indebted to Mr Theobald, who has 

 kindly examined it for me. 



Subfamily Chermisin/E. 



Genus Chermes, Linn. 



Chermes abietis, Linn. The galls of this species were only too 

 abundant on spruce-fir at Swordale. I took ovigerous females and 

 their eggs on spruce-fir on 31st July. 



Chermes picece, Ratz. Autumn females and eggs of this species 

 were abundant under white downy matter on the bark of silver-fir 

 {Abies pectinata), at Dingwall, on 6th October.
