Podothrips propinquus, sp. n. 



? . — Length about 1*5 mm. 



This form comes very near to P. duplicates, sp. n. It is 

 larger and somewhat more robust. The distal fourth or 

 thereabouts of the fore-femora is light yellow ; tho anteunal 

 joints 3 and 4 are yellow, the latter lightly touched with 

 brown. 



The prothorax is comparatively shorter and more strongly 

 transverse, and the posterior seta? at least (also strongly 

 dilated distally) are distinctly longer than in duplicates (6 : 4), 

 those at posterior angles being 0*55 and those at anterior 

 angles about 0'35 the median length of the pronotum. The 

 fore-tibia is produced into the form of a tooth at the apex 

 within, but there does not appear to be a fore-tarsal tooth 

 (one fore-foot is broken off and the other tucked under the 

 head in the unique example). The relative lengths of the 

 antennal joints 3 to 8 are as follows :— 18 : 20 : 16 : 15 : 

 16 : 14. 



There are 6-7 duplicated cilia in the fore-wings. 



The tube is stouter basally, being about. 0*55 as broad at 

 base as long and a little less than half (0*47) as broad 

 at apex as at base, 0'62 as long as tho head. Terminal hairs 

 short and weak.

Trichothrips group. 



Genus EURHYNCIIOTIIRIPS, UOV. 



<J . — Head not as long as broad, with sides converging 

 posteriorly, slightly longer than prothorax. Mouth-cone long, 

 sides straightly narrowed to apex, reaching across prosternurr, 

 and as long as the dorsal length of head. Antennae 8-jointed, 

 all joints well separated. Ocelli well forward, the anterior 

 ocellus directed forwards. 



Prothorax strongly transverse, more than twice as broad
