ii2 Indian Museum Notes. [Vol. V. 



An examination of Mr. Buckton's specimens and drawing show 

 clearly that P, obsoleta must belong to the Triozime t and from the 

 form of head and general structure I should place it in the genus 

 Trioza, but the aborted hind wings (if constant) might justify creat- 

 ing a new genus for its reception, 



With one exception all the Australian gall-making Psyllidae be- 

 long to the Triozinse, but I have never found any species without 

 well developed hind wings, when they have emerged from the galls 

 of their own accord.
