Hab. — New Holland (Westwood) ; Tasmania (Masters). 



Ohs. — I have no doubt that the above-described is the <^ oi G. 

 cyanea, Westw. Westwood states that this species appears to be 

 very closely allied to Limnophila metallica, Sch., but the latter is 

 a yery different insect as can be seen both from Dr. Schiner's and 

 my description. It would be interesting to know if the male has 

 the three first branches of the flagellar joints directed outwards ; 

 Westwood places this species in the same section with G. vilis.
