 scribed : — 



Fhysothrips minor, sp. n. 



,, andrewsi, sp. n. 



Megathrips lionoris, sp. n. 

 Baciridothrips serndicornis, sp. n. 



Elaph'othrips antenncdis, sp. n. 

 Dicaiothrips crassiccps, sp. ii.

Fhysothrips minor, sp, n. 



? . — Length about I'O mm. 



Belonging to the P. usitatns group. 



Colour dark brown; fore-ti hire pale yellowish, lightly shaded 

 Avitu grey-brown basally, intermediate and bind-tibiee at tips 

 and all tarsi pale yellow; third antenna! joint pale yellow, 

 for tlie most part shaded with grey. Fore- wing daik grey- 

 brown, excepting basal fifth or thereabouts, where it is light. 



P. atitennatus type.— Eyes coarsely facetted, pilose ; 

 ocelli large, interocellar setae situated between posterior 

 ocelli, long and stout. Maxillary palpi long and slender. 



Antennas as in antennatus, Bagn., but joints 3 and 4 not so 

 strongly produced distally; 4 longer than any other joint ; 

 3 apparently short on account of being very broad near 

 middle ; 5 with a very short stem-like constriction ; relative 

 lengths of 3 to 8 approximately 39 (with stem) : 46 : 33 : 41 : 

 8 : 13. Forked trichomes on 3 and 4 stout. 



Upper vein with a series of setse running to tlie distal third 

 and two at tip ; those of posterior vein long, coirimencing at 

 the second setse of the upper vein. 



Abdominal segments 8-10 obcouical ; terminal setse long 

 and strong, those on 9 approximately 1*4 times the length of 

 the segment. Eighth tergite posteriorly without fringe. 



This species comes near to P. antennatua, Bngn., and 

 P. antennalis, Karny, and is distinguished from botli by the 

 small size and the relatively shorter joint 4 of the antenna?.
