mencing at basal third. Body elongate, only slightly broader 

 than the pterothorax. Apical segment about 0*2 shorter 

 than ninth abdominal segment ; bristles long, nearly as long- 

 as the two apical segments together. 



This species differs from both sjostedti (Tryb.) and varia- 

 bilis, sp. n., in the long series of bristles in the lower vein 

 commencing at the basal third, instead of with the corre- 

 sponding series of upper vein at the basal fourth.

Physothrips variabilis, sp. n. 



$ . — Length 1*1 to 1*6 mm. 



Near sjostedti (Tryb.) and usitatus, 'sp. n., but broader. 

 Dark specimens dark chestnut-brown ; third antennal joint 

 yellow ; fore-tibi?e yellowish ; intermediate and hind-tibiae 

 grey-brown ; all tarsi yellowish. Light specimens light-grey 

 to yellowish-brown ; pterothorax lighter and abdominal 

 segments 1 to 7 yellowish, only slightly tinged with grey- 

 brown.. Fore-wings and cilia light greyish-yellow, a lighter 

 patch near apex ; basal third clear. Upper vein with three 

 basal spines, a series of 9 to 14 commencing at about the 

 first fourth, and running well into the distal fourth on to the 

 distal fifth ; 2 at extreme apex. Spines of lower vein com- 

 mencing also at the distal fourth. Head transverse, shorter 

 than prothorax; eyes pilose. Relative lengths of antennal 

 joints 3 to 8 :— 23 : 24 : 16 : 24 : 5 : 6. Double trichomes 

 on segments 3 and 4 very large. Abdominal bristles long. 

 Legs sparingly spinose. 



Differs from sjostedti (Tryb.) and tisitatus, sp. n., by the 

 broad form and transverse head and by the long series of 

 spines in the upper vein of fore-wing extending to beyond 

 the basal fourth.

Thrips assimilis, sp. n.
