mottling the head and thorax and marbling the segments of the 
abdomen, the head behind the eyes and the abdomen frosted 
with silvery pubescence; ventral surface grey except the abdomen 
which is black, and the covers of the drums which are reddish- 
pink, flat and placed behind the hind legs. 
I am told by some of my young friends that this is called the 
" Mottled Grey," but do not think that the name is in general use. 
I had never seen more than half-a-dozen specimens of this species 
until last year, when they appeared in considerable numbers, but 
chiefly in the neighbourhood of Hurstville and Sutherland; a few 
were taken about Middle Harbour and others at Granville. 
Melampsalta melanopygia, Germ. 
Expanse of wings 2 inches, width across the shoulders 3 lines, 
length of body 10 lines. Wings hyaline, costal nervure of both 
wings and the two inner nervures of the hind ones yellowish-

Head and thorax chestnut brown mottled with black and clothed 
with fine white hairs scattered over the dorsal surface, but much 
closer upon the legs and undersurface; legs chestnut striped with 
black, the scutellum small, forming four angular star-like ribs, the 
abdomen at the base and along the summit black, the sides, tip 
and undersurface golden yellow, lightly clothed with fine hairs. 
This is the first Cicada to appear about Sydney, the earliest 
specimens being taken on the last day of October at Hornsby. 
They are very active little fellows, flying about and clinging to 
the stems of the young Eucalypts, calling with a sharp whirring 
note all the time. I have taken a few of these every season 
about Hornsby and Middle Harbour, but they do not last long, 
disappearing in a few weeks. 
Melampsalta encaustica, Germ. 
Expanse of wing If inches, width across the shoulders 3 lines, 
length of body 8 lines. Wings slightly opaque, all the larger 
nervures brown lined on either side with black, all the smaller
