genera Liothrips and Hoodia. 475 



these two differ also considerably from each other in the 

 shape of the mouth-cones. I have already briefly described 

 this difference in the table, and think I can best visualise 

 it by saying that, in this respect, Hoodia austriaca recalls 

 G'piaikothnjis iizcli, whereas Hoodia hagnalli recalls 

 Mcsothrips jordani.^ 



I believe that I have now demonstrated that Liothrips 

 hradecensis, Bagnall, is not identical with Uzel's species, 

 but represents a new species, which can be clearly differ- 

 entiated from all known species of Liotliri2JS, and is most 

 closely allied to my Hoodia austriaca. I \\dme allowed 

 myself the pleasure of naming this interesting new species 

 after its discoverer.
