Note. — Goding and Froggatt describe (Proc. Linn. Soc. 

 N.S.W., 1904, p. 589) Psaltoda plebeia. In the Macleay Museum 

 there are a number of specimens, one of which is marked " Zipa, 

 on locust trees." Two of these have been labelled as the types 

 of P. plebeia, God. and Frog. The species is, as a matter of 

 fact, Cicada plcbeja, Scop., of the Mediterranean littoral. In 

 *one instance the usual chestnut colour of the pronotum has been 

 replaced by yellow.
