NOTES ON CICADAS. 
ones black. Head and thorax black, with a spot behind the ocelli, 
a parallel line down the centre of the prothorax, and two similar 
ones crossing the mesothorax light brown; the ridges of the 
scutellum of a similar colour but tinged with pink, with several 
other pink marks above the antennae and sides of the thorax; 
abdominal segments black, with a narrow apical transverse band 
of pale yellow, extending right round, the tip bright yellow; legs 
variegated with black and white, striped with pinkish-yellow. 
This is one of our smallest species, seeming to take the place of 
the preceding species in the Shoalhaven district. 
Three other fine species not yet determined were also taken, 
but as far as I know are very rare, only a pair of each having 
been found during the last three seasons. 
Tibicina sp. A handsome dark chestnut-brown insect measur- 
ing 3^ inches across the wings, with two black spots towards the 
tips of the forewings, and the sides of the thorax and abdomen 
clothed with fine white hairs, very thick upon the latter, the costal 
nervure of the forewings also mottled with similar pubescence. 
Psaltoda sp. A large black Cicada with an expanse of 4 
inches across the wings, the nervures being tinted with reddish- 
brown; the male has a large patch of bright golden hairs on the 
sides of the third segment of the abdomen, absent in the female. 
Psaltoda sp. A slightly smaller insect, similar in general 
colouration, but the blotch upon the side of the abdomen of a 
bright silvery colour.
