3. Pterochlorus roboris (Fabr.). 



There are no specimens of this species in either the Walker 

 or Buckton collections and it is included here onlv hecause it 

 has been recorded by Morley 5 from the Isle of Wight, although 

 it is possible that he had the same species as did Walker and 

 followed him in naming it. However Lainge tells the writer 

 that it is a very common species throughout England and 

 Scotland. 



4. Pterochlorus cistatus (Walker) Buckton. 



What this species is the writer has no idea as Buckton's de- 

 scription is very meagre and there are no specimens in either 

 collection that could very well fit the description. 



5. Pterochlorus viminalis (Boyer). Buckton; four slides (2 alate, 

 2 apterous 99); "saligna Sulz." taken from willow at Charshalton. 



This is a common species in southeastern England, and for 

 that matter throughout Europe and America. Morley has re- 

 corded it from Ipswich and Theobald from Kent. 



Sub-tribe Eulachnma. 



6. Eulachnus agilis (Kalt.). Walker; three slides (2 alate, 4 

 apterous, 1 immature 991: "aailis: Scotch Pine; Southgate; June 15- 

 47." Buckton; two slides (2 apterous, 3 immature 99); "ayilis." 

 These specimens differ from Kaltenbach's description in that the 

 sixth antennal segment of the alate female is subequal to the fifth 

 and not "half as long as the fifth." 



Koch figures the apterous of this species as a variety of 

 pinctl Fabr. Cholodkovsky states that the fourth antennal seg- 

 ment in the alate female is a little shorter than the fifth and 

 much longer than the sixth. In these specimens, however, thev 

 are all three subequal. This is without doubt the true E. agili\- 

 (Kalt.). Theobald records this species from Kent. Morley 

 from Suffolk, and Miss Jackson" from Scotland. 



Sub-tribe Lachtiina. 



7. Lachnus fasciatus Burm. Walker; two slides (2 alate, 3 apterous 

 99); "cnstata; Spruce fir; Southgate; June L'.VIT." (Also June 

 30-47).
