In No.4 of this series of Studies (15, pp.271, 289), I gave my 

 reasons for considering the Psycho2)sid(e to be a separate family, 

 and stated that it was my intention to deal with these insects in 

 a monograph to follow later. 



In a paper read in October, 1915(13), but unfortunatel}^ not 

 bearing upon it any indication of the actual date of publication, 

 Navas published, in Spain, a monograph of these insects, and 

 classified them as a separate family. This paper has only recently 

 reached me, and I cannot tell whether it should take priority 

 over mine or not; however, in view of the earlier date of reading 

 of Navas' paper, I feel that I must give him the credit of having 

 first raised these insects to family rank. 



The conditions arising from the War have made it impossible 

 for me to receive, for study, the material that I had hoped for, 

 in the non- Australian species of this family. For this reason, 

 as well as because of the publication of Navas' paper, I have 

 decided to abandon my projected monograph, and to confine 

 myself mainly to a study of the Australian species. Only in so 

 far as this study aflfects the classification of the family, will it be 

 necessary to discuss the other genera and species. 



During the past three years, a large amount of work has been 

 carried out upon this family. Of special importance has been 

 the working-out in detail of the life-history of one species, 

 Psychopsis flegans (Guerin), and the dissection and photographing
