Tvpe in Coll. Tillyard. (Brisbane, (^)., T. Batchelor, Dec, 

 11)01). A second male in my collecti(jn, taken by the same 

 collector in Jan., 1901. Two other males from the same series 

 are in the collection of the Queensland Agricultural Department, 

 from whom the two males in my own collection were received in 

 exchange. 



U,ilj, — Brisbane, (^>. The locality where they were taken is 

 not exactly known, but is, in most i)robability, built over long 

 a"o; so that it is possible that this species is already extinct. 



I dedicate this very rare species to Mr. Henry Tryon, F.E.lS., 

 Govei-nment Entomologist of Queensland, to whom T am indebted 

 for the opportunity »-)f studying it. 



This new species closely resembles 7'. <J<>deff'royi Selys, in gen- 

 eral appearance: but may be distinguished from it at once by the 

 much longer pterostigma and the great difierence in the form of 

 the anal appendages.
