2. The synonomy of thi.s genus requires clenring up. D. colrop- 

 Irnta G. & F appears not to be identical with Walker's species, 

 ■ind may possibly be the same as D. riches) Dist. 



Kirkaldy fives the new name, D. tasmani for D. colcoptratn 

 Walk, without stating reasons; the change does not seem xo be 

 necessary. 



3 A pupal skin of a TrttionTCti that seems to differ from the 

 imago of T. lormcntose (I have not seen the pupal skin of tftis 

 .■^necies), was taken on Mt. Maria, Miu-ia Isl,, on the 5th April, 1915. 

 This may prove to be a new species.
