 (Buffa) ; England. 



LlOTHRIPS HRADKCENSIS, Uzel. 



" Monograpliie der Orduimo- Tlivsanoptera," p. 262, pi. vii, fig. 

 146, 1895. 



The antennae of Linthripi^ setinodis (Rent.) are clear yellow, ex- 

 cepting only the two basal joints and the eighth joint which are dark 

 brown, whilst in L. hradecensh, Uzel, the third joint only is clear 

 yellow, the fourth and fifth joints being tinged with brown distally, 

 and the apical half of the sixth and the whole of the seventli and 

 eighth joints are dark brown. 



In July of this year I discovered a number of Liothrips hradecen- 

 sis, Uzel, on the under-side of the leaves of elms growing by the 

 Durham banks of the Tees near Piercebridge, and on re-exainining 

 the specimen found on elm at Gibside, and recorded by me (Ent. Mo. 

 Mag., xliv, p. 4, 1908) as L. setinodis, I find that it is referable to 

 L. hradecensis also, whilst there are two unlabelled examples (probably 

 from the south of England) in the British Museum. 



The species was described by Uzel from a single ? found on the 

 im der- side of the leaf of Heracleum, sjjhondylium, in September, 

 Bohemia. 



Distribution : — Bohemia (Uzel) ; England. 



Genus ACANTHOTHRIPS, Uzel. 

 Acanthothbips nodicornis (Reutei"). 



Pliloeothrips nodicornis, Reuter, " Thvsauoptei'a Fennica," p. 16. 

 1880. 



There is a single imperfect and pinned example of this distinct 

 insect in the British Museum, milabelled, but probably from the South 

 of England. 



This form is the Phlwothrips vlmi (1836) and P. coriacea (1839) 

 of Burmeister, and apparently th(\ Hoplotlirips corticis of Amyot and 

 Serville. 



Until this year, A. nodicornis (Reut.) was the only Ein-opean 

 representative of the genus, but we have recently described a second 

 species, A. bidens, Bagnal], from Hiuigary, easily distinguished by the 

 two small teeth at the apex of the fore-femur within, and the ex- 

 ceptionally long bristle at each anterior angle of the prothorax. 



Distribution : — Apparently of wide European distrilnition, and 

 recently recorded from North America.
