Rieardo's description, until a specimen can be compared with the 

 type. 



Specimens were taken at Kendall from November 25th to 

 April 4th, but the species was rare and not always distinguished 

 in the field from T. circumdatus. 



Specimens are in the collection of the Department of Public 

 Health from Wolseley Park and Wee Jasper.

Postscript, added 10th February, 1920. — The species somewhat 

 doubtfully identified as E. contigua Walker, E. quadrimacula 

 Walk., and D. crassa Walk, have proved, by comparison of 

 specimens with the types, to be correctly named. We are in- 

 debted to Dr. Guy Marshall, of the Imperial Bureau of En- 

 tomology, for these and other determinations.
