one from Guildford, one from Eleet, and one labelled "ex coll. 

 Capron " ; these are var. Jucunda, Weise, which name is also applied 

 to examples with blue elytra in which the head and thorax are blue- 

 green or aeneous. Mr. E. A. Butler has two specimens of vav. jucunda 

 which he took at Bray, in August, 1893. 



C. aurea, Geoffr. — This species in its prevalent form has the 

 upperside entirely coppery-bronze, but green examples are not 

 uncommon, and, if dark green, they are var. Iceta, Weise. Then there 

 is the dark form, cyanea, Marsh., with the upper-side dark blue, violet- 

 blue, or greenish-blue and the antennae and legs somewhat darker 

 than usual. Bright blue specimens with the antennae and legs 

 entirely yellow are var. gaudens, Steph., of which I have seen an 

 example from Ditchling, Sussex, ex coll. Britten. Var. cyanea I have 

 seen from Chattenden, Kent, Weybridge, Surrey (Champion) ; Col- 

 chester (Harwood) ; and I am indebted to Mr. E. A. Waterhouse for 

 an interesting account of its occurrence at Glemsford, Suffolk, on 

 June 5th, 1897. In a wood there, some parts of which were pretty 

 well carpeted with the oxlip, C. aurea was fairly abundant on aspen, 

 and on two particular bushes growing together there were at least 

 as many blue as coppery specimens. At the request of Mr. C. O. 

 Waterhouse, to whom I applied on the subject, Mr. Gahan has been 

 good enough to examine Marsham's examples of cyanea, and he finds 

 that they agree wholly, except in colour, with C. aurea. This is 

 noteworthy in view of the fact that Everts (Col. Neerl. ii. p. 463) 

 puts cyanea, Marsh., as a variety of smaragdina, Foudr.

NOTES ON TEYSANOPTERA (TUBULIFERAJ NEW TO THE 



BRITISH FAUNA, WITH 



DESCRIPTION OF A NEW SPECIES OF MEGATHRIPS. 



BY RICHAED S. BAGNALL, F.E.S. 



Since my last paper on new genera and species of British 

 Thysanoptera (Ent. Mo. Mag., Ser. 2, vol. xix, pp 3 — 7, 1908) was 

 published I have had the opportunity of collecting and examining 

 further material, including thirteen species new to the fauna of the 

 British Isles, four of which are referable to the Tuhulifera and form 

 the subject of this preliminary paper. 



Gryptotlirips dentipes, Renter, has already been recorded from
