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 

 chiefl}^ 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- 

 brown edged with black on both sides, all the others black. 

 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 l|i 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
