This genus is evidently one of the dominant tyjies of Thysanoptera in Queens- 

 land, and its species will no doubt be found to inhabit the under surface of the leaves 

 of woody plants. The forms which the writer has assigned here are not all typical 

 members of the genus, and it may be necessary in time to remove to another genus 

 those placed under the category '' aa " in the key below. Further collecting and 

 much additional material will be required, however, before this and other doubtful 

 points can be settled. 



It may not be inopportune to remark that in the key to the North American 

 species of this genus, given in the last paper cited above, its author includes macoimelli 

 (a mis-spelling of mcconnelU) and jasciculatus, both of which were transferred to the 

 genus Leptothrips in 1912 ; that six North American species (leucogonis, castanece, 

 brevicornis, sambuci, montanus, and varicornis), originally described in this genus, as 

 well as four others properly referable to it, are omitted entirely ; that the new species 

 flavoantennis is apparently identical with citricornis Hood, described in 1908 ; and 

 that the description and figure of the new subspecies of caryce Fitch are not sufficient 

 to distinguish it from the typical form, having unfortunately been based merely on 

 teneral material. The described North American species of this genus, as interj)reted 

 by the ■writer, may be listed in alphabetical order as follows : —
