BAGNALL'S THYSANOPTERA 49 



can be seen between the two nominal species. Ph. latus closely resembles salicis 

 Reuter, the type-species of Physothrips, in the chaetotaxy of the ocellar region, the 

 prothorax hind margin, the wings, and the metanotum. A metathoracic furcal 

 spinula is indicated in some members of a series collected from Bettila sp. leaves in 

 Scotland by the present author. Taeniothrips decoratus Pelikan (1965 : 99-102), 

 from the description, is closely related. 



Holotype $. England : Northumberland, Ninebanks, near Whitfield, Scabiosa, 

 Summer 191 1 (H. S. Wallace). 



Holotype $ of propinquus. England : Oxford, Pinus, vii.1914 (R.S.B.). 



Physothrips setiventris Bagnall 



Physothrips setiventris Bagnall, 1918b : 61-63. 



This species resembles salicis Reuter, the type-species of Physothrips, in the 

 chaetotaxy of the ocellar region, the prothorax hind margin, the wings, and the 

 metanotum. The eighth tergal comb is long and fine and a spinula is present on the 

 metathoracic furca. However, the sternites bear twelve to twenty accessory setae 

 and the tergites are covered laterally with numerous microtrichia. Ph. setiventris 

 appears to be intermediate between Physothrips and Mycterothrips. 



Holotype $. India : Darjeeling, Ringtong, on tea bush, 14.vi.1916 (E. H. 



A ndrews) . 



Platythrips tunicatus (Haliday) 



Thrips tunicata Haliday, 1852 : 11 15. 

 Bolacothrips nigricornis Bagnall, 1913k : 239. 

 Platythrips tunicatus (Haliday) ; Bagnall, i928d : 130. 



Bagnall's species nigricornis was based on a single male. This specimen was 

 subsequently recognized as the male of tunicatus Haliday but the preparation has 

 now turned black. 



Holotype $ of nigricornis. England : Oxfordshire, Weston-on-the-Green, on 

 sedge, viii.1913 (R.S.B.). 



Prosopothrips nigriceps Bagnall 



Prosopothrips nigriceps Bagnall, 1927b : 570. 



This species differs from the type of the genus, rejdovskyi Uzel, in the yellow pro- 

 thorax and the shorter antennal segments. In the sixteen females available, 

 antennal III is less than twice as long as broad, whereas in the single female rejdovskyi 

 examined, antennal III is more than twice as long as broad. 



Syntypes $. France : Hyeres-la-Plage, on a small beach grass, ix.1927 (R.S.B.).
