DESCRIPTION OF A NEW SPECIES OF lODIS, WITH 

 REMARKS ON PIELUS IMPERIALIS, Olliff. 



By Thomas P. Lucas, M.R.C.S,, L.S.A., Lond., L.R.C.P., Edin. 



The past season in Brisbane Las been most unfavourable for 

 the appearance of Lepidoptera. Many of the new species of 

 lodis I found last year have not turned up at all, and all have 

 been rare. I have found /. leucomerata here for the first time. 

 I obtained one worn specimen of a new species early in the year, 

 but must wait for describing until I obtain better specimens. 

 But last April Mr. Illidge was fortunate enough to discover a 

 novel and most interesting species on a small tree growing in 

 his garden, which he had transplanted from the bush. With a 

 lantern light he discovered the imago flying rapidly around the 

 tree, and afterwards Mrs. Illidge found the pupa cases in very 

 light cocoons among the leaves, evidently showing that the larvas 

 had fed there, and that the moths were there to deposit their 

 eggs. I have great pleasure in naming the species after its 

 discoverer.
