DESCRIPTIONS OF SOME NEW SPECIES OF BRITISH 

 THYSANOPTERA (TUBULIFERA) . 



BT RICHARD S. BAGNALL, F.L.S. 



{Hope Department of Zoology, University Museum, Oxford.) 



In the following notes I have pleasure in describing four new and 

 interesting species of Tuhnlifera. Two of these fall into the genus 

 Hoplandrothrips — a genus separated from Phlwothrips, s. str., by the 

 presence in the male of two small teeth at the tip of the foi-e-feinur 

 within, and — usually — a similar tooth near the base of the fore-tibiae 

 within. Representatives are known from Europe, North America, and 

 Africa. 



Haplothrips obscuripennis, $2). n. 



? . Length, 1'4 to 1'6 mm. 



Comes nearest to H. juncoruni, Bagn., and H. aculeatus (Fabr.). 

 Colour very deep brownish-black, as in juncorum ; fore-tibia yellowish, 

 shaded with dark grey-bro%vn basally and along the iipper and lower margins ; 

 intermediate and hind tibial lighter at extreme tips ; all tarsi yellowish. 

 Antennae with third joint yellowish, shaded with grey apically, 4 and 5 grey- 

 brown with basal third at least, yellow, somewhat sharply defined; 6 to 8 

 darker grey-brown, the sixth with basal fourth yellowish. 



Head abovit 1'6 times as long as the prothorax and 1-15 times as long as 

 broad. Cheeks slightly arched. Postocxilar bristles long. Mouth-cone not
