532 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 antennse 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 j)lace 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.
