soft in structure. Tn mounted specimens the rostrum is often very 

 conspicuous, and as a rule the front pair of legs are much more 

 prominent than the antennae. 



The winged specimens are much the same in colour as the above. 

 They may be beaten from 

 Scots pine trees throughout 

 the summer, and as the 

 wings are often folded flat 

 over the body, they might 

 be mistaken by a beginner 

 in entomology for a species 

 of ant. 



Lachnus longipes, Dufour. 



This species is found on 

 oak, and often on young 

 shoots from oak stools. The 

 eggs, however, as represented 

 in fig. 286, are the most 

 conspicuous. They may be 

 looked for in late autumn or 

 during the winter months. 



In early summer the apter- 

 ous viviparous females may 

 be found in masses on the 

 shoots of oaks which grow 

 as suckers from the stools 

 or stumps of previously

felled trees. They are 



fairly large in size, of 



oval form, and of a uniformly deep-brown colour. Eyes black, and 



cornicles small. 



Lachnus viminalis (Fonsc.) 



This species is found fairly common in some parts of the country 

 on willow or osiers, and very harmful to willows and osiers in parts 

 of South England. Wasps are greatly attracted to where they occur.
