Of the cicadas described beh)w. two belong to the distinc- 

 tively Australian genus Macrof ri stria ^ and come fi'oni Xoi'thern 

 Australia, having been given to nie by Mr. Chas. French, junr. 

 Government Entomologist. One of them is remarkable for its re- 

 semblance to Thopha Sessiliba, Dist. so closely resembling it in 

 general appearance that it might even be mistaken on a passing 

 glance. Tlie otlier is not remarkable in any way except for its 

 almost uniform chestnut colour. In this it resembles M. ingrnsig- 

 nata, Dist., but it is distinct from this species in its more .sessile 

 eyes, its nai'i'ower thorax, and the lack of the Ijlack basal area and 

 membrane to the tegmina. I have named it after Mr. Fiench. The 

 • other tAVo belong to the genus Psalfor/a. one of tliem cominir from 

 Lord Howe Island.
