ON A NEW SPECIES OF PHLCEOTHRIPlD>E 



OF JAPAN. 



By 



HAN8LRO Okat^ioto, Nögukus^.i. 



The inseot, which I propose to describe below, Mas first found crawliiiir inside 

 the cor(^)lla of a flower of daizu (Glycine hispida Maxim.) by my friend, ^Ir. Y. 

 TaKAHASHI of the Hokkaido Agricultural Experiment Station, while lie was 

 making crossing experiments with this crop. He found afterwards, that the iassect 

 is pretty common upi>n this as well as upon .some other legumini>us ])lants, .such as 

 azuki [Adzukia subtrilobata Tak.), sasage (Mgmt sinensis Hattk ) etc., tlic pollen 

 grains apparently being damaged by this insect. H^ collected both larval and adult 

 forms of the insect and kindly placed the.se specimens at my disposjd. 



The iu.sect in question belongs to the family Phheothripidse and seems to be 

 new to the .scientific world. 



Its characteristic may be described as follows : 



Liotlirips glycinicola n. sp.

 bieadth; geuje on its .side nearly straight and parallel, without nijiple>. Eyes dark-
