2G0 Mr. R. S. Bagnall on new Thysanoptera.

Ileliotlirips minutissimus, sp. n. 



Length, $ , c. 0*65 mm. ; <$ , c. 0"5 mm. 



Same form as II. i adieus, Bagn., but much smaller, practi- 

 cally colourless — greyish-white to greyish-yellow, — though 

 probably more deeply coloured in fresh examples ; wings 

 apparently of a light grey-brown. Unfortunately theexamples 

 at my disposal are too poorly preserved for a satisfactory 

 description, but happily the special series of bristles on the 

 ninth tergite of the male are clearly shown, demonstrating 

 at once (apart from the great difference in size) that the 

 species is not a colourless form of indicus. There are six long 

 bristles arranged in the form of a crescent, the outside pair 

 being the highest and practically mid-lateral, and the 

 inmost pair the lowest, quite near the posterior margins. 



Type. In Coll. Bagnall, University Museum, Oxford.
