NOTES ON SOME THYSANOPTERA 



liy ISiolinril .*£. EC.-i^m.iIj 

 (Penshaw Lodge, Penshaw, Co. Durham). 



In the following notes I am able to redescribe the type spécimen 

 of Butler's Anthothripa (Aptinothripsl) fasciatus; to show that the 

 North American Grass thrips (Anaphothrips striatus) is the saine as 

 the older Enropean form A. obscurus, and also make other notes 

 that may be of use to students of the Thysanoptera. 



Sub-order TERBBRANTIA. 

 Genns HETEROTHRIPS Hood (nec Buffa) (1). 



Phyllothrips Buffa (nec Hood) (2). 



In a paper pnblished in December 1908, Buffa described two 

 gênera to which he gave the names Phyllothrips and Heterothrips (2) 

 both of which had been used a few months before by Hood. Recog- 

 nising that the latter name was preoccupied, Buffa proposed a 

 new name Polyommatotitrîps(3), but doesnot make any remark abont 

 his Phyllothrips. The synonymy is still further confused by the fact 

 that Hood's name Heterothrips was erected for a similar form as the 

 type of Iîuffa's Phyllothrips and this latter name must be sunk not 

 only because the name had already been used but also on account of 

 the fact that the genus had previously been diagnosed under the 

 name Heterothrips. 



The genus Phyllothrips Hood was erected for the réception 

 of the type form /'. cîtricornis Hood, and Hind's Cryptothrips 

 aspersus. Both M r Hood and I agrée that the first named should 

 be referredto the genus Liothrips, and being the type of the genus 

 Phyllothrips that name becomes a synonym of Liothrips whilst 

 Hood later proposes the name Leptothrips with C. aspersus as the 

 type of the genus. 



ANAPHOTHRIPS OBSCURUS (MQll). 



Anaphothrips striatus (Osborn). 



Anaphothrips striatus (Osborn) must be regarded as a synonym of 

 Anaphothrips obscurus.
