48 BEITISH APHIDES. 



solitary in habit, being mostly found singly on tlie 

 green fir tufts. Towards the end of June or the 

 beginning of July they split their integuments and 

 disclose the imagos. 



Winged viviparous female. 



Incli. Millimetres. 



Expanse of wings 0*200 5*08. 



Size of body 0-070 X 0025 177 X 0-62. 



Length of antennae 0'035 0'88. 

 Cornicles wartlike. 



Green, slightly mealy. Antennae and eyes brown. 

 Thorax pale reddish brown. Legs long, yellowish 

 green, with dark femoral and tarsal tips. Wings rela- 

 tively small. Stigmata long, and stigmatic veins con- 

 tinued in straight lines beyond the same. The furcal 

 veins are often difiBcult to trace from their paleness of 

 colour and tenuity. The vertex is tufted with capitate 

 hairs ; the rostrum is rather short, and reaches only 

 to the third coxce. The apical rings are almost free from 

 bristles, and rather attenuated. I suspect that Koch 

 has in his figure 304 drawn an immature specimen of 

 Lachnus agilis for Laclmus pineti. 



Taken at Haslemere and Bramshot, Surrey, in 

 June. Mr. Walker also forwarded me examples from 

 Walthamstow. The winged forms are difficult to meet 

 with.
