IJeh'othrips mmutissimus, sp. n. 



Length, $ , c. 0*65 mm. ; $ , c. 0'5 mm. 



Same form as 77. indtcus, Bagn., but mueli smiller, practi- 

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

 probably more deeply coloured in fresh examples ; wings 

 apparently of a light grey-brown. Unfortunately the examples 

 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 indicut. 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.
