Maadibles and clj^peiis coloured a? in the c?. Apex of clypeus on the 

 right side yellow ( cj' ) <'ii tl'e left redder ( 5 ), but on the former side the inner 

 orbits have the red line as in the 2 . White hairs of face dense on more than 

 the right half [S ) but the rest barer, as in the 9- Eight antenna normal

 red spot (5), right side with only a trace. In normal c? it is unspotted. 

 Propodeum on right side with long pube.^cence, on the left glabrous. Beneath 

 and at the sides the thorax is male, but the hairs are less dense than in normal 

 specimens. The right hind leg is evidently (^ , the femur being densely 

 punctured beneath and minutely and densely pubescent, not shining and 

 nearly glabrous like the left, which is $. Abdomen entirely $, the tip of 

 the sting is visible. 



The occurrence of such an individual is remarkable, the species 

 being so uncommon in Devonshire that I do not see moi-e than one 

 living specimen in two or three years on an average.

DENDEOTHEIPS OENATUS (Jabl.), 

 A SPECIES OF THYSANOPTERA NEW TO THE BRITISH FAUNA. 



BY EICHA.BD S. BAGNALL, F.Ii.S.E., F.L.S. 



During the visit of the British Association for the Advancement of 

 Science at Edinburgh this year (1921), I spent a week-end at Crieff 

 motoring round Loch Tay on September lOtli. 



At the end of the Loch and a mile or two beyond Taymouth Castle 

 (near Kenmore) I was pleased to find a single specimen of Dendrothrips 

 ornatus on lime, with numerous examples of Bagnallia calcarata 

 (Uzel). 



Dendrothrips ornatus (Jabl.). 



1894. Thrips ornata Jablonowski, Termesz. Fuzetek, xvii, pp. 93- 

 99, pi. iv. 



1895. Bendrothrips filiae Uzel, Mon. Ordnimg Thysanoptera, 

 pp. 160-162, pi. ii, f. 15 and pi. vi, figs. 84-86. 



1914. Dendroth'ips ornatus Bagnall, Ann. Mag. Nat. Hist., ser. 8, 

 xiii, p. 297. 



This insect, better known as B. tiliae, affects lime, and is recorded 

 from several Central European countries, Avhilst I have taken it in South 

 Norway. It is a short, squat species, with banded wings, and belongs to 

 a very distinctive genus.
