Mr. R. S. Bagnall 07i neio Thysanoptera. 23 



This species somewhat closely resembles Euthrips cinyu- 

 Jatus, Kaniy, from which it is easily separated by the pro- 

 thoracic bristle at each hind-an^le, the uniform ligiit yellow 

 colour of body, and the coloration of the anteniiEe. The 

 coloration of the wings is about the same. The relative 

 len^rfhs of the antennal joints are also distinctive. 



Type. In British Museum of Natural History.

Pseudothrips glaucus, sp. n. 



$ . — Lcngtli 0'95, breadth of rnesothorax 0*28 mm. 



General colour light grey-brown, apes of abdomen slightly 

 darker ; legs somewhat lighter than the body. Antennee 

 darker grey-brown, with joints 1 and 3 a little lighter. 

 Wings greyish yellow. 



Head transverse, about 0'65 as long as broad, practically 

 as long as prothorax. ^louth-cone almost reaching across 

 prosternum ; palpi rather long. Antennae more than twice 

 as long as head ; joint 3 pedicellate, 6 simple, not divided. 

 Relative lengths of joints approximately : — 10 : 22 : 27 : 

 2i : 22 : 26 : 5 : 8. 



Prothorax 1*85 times as broad as long, one long and stout 

 bristle near each hind-ano;le. Pterothorax larffe. Legfs 

 moderately long and stout. Wings long, reaching almost to 

 tip of abdomen ; upper vein of fore-wing with an unbroken 

 series of 15-18, and lower vein with 13-15 setK. 



Abdomen elongate-ovate, posterior margin of eiglith tergite 

 fringed. Bristles at hind-margin of ninth tergite long, but 

 those of tenth comparatively short, excepting a pair ot long 

 dorsal bristles. 



This species is easily separated from P. inequalis (Beach) 

 by its colour, the undivided sixth antennal joint (and relative 

 lengths of joints)^ shorter prothorax, and presence of dorsal 

 bristles on tenth abdominal segment.
