marked preference for the Pittosporum trees. Though I caught 
numbers, I could obtain no females until the 24th of November, 
three weeks after the first males appeared, but after that date 
they were nearly as plentiful as the other sex. 
There is a yellow variety of this species, which is popularly 
called the " Yellow Monday;" the only difference that I can find 
is in the colour, but they are nothing like as common as the 
green one. 
Macrouistria angularis, Germ. ("The Union Jack"). 
Expanse of wings 5 inches, width of shoulders 9 lines, length 
of body If inches. Wings hyaline, the nervures pale ochreous- 
yellow, close to the shoulders reddish-brown, the nervures form-

line of black on both sides, giving the wings a slightly mottled 
appearance. General colour of the insect black, with the front 
of the head, mesothoracic band, and the apex of the metathorax 
dark ferruginous; three patches in a line between the eyes with 
another behind them, a row of three elongate spots in the centre 
of the prothorax, and a row of four slender transverse spots along 
the middle of the metathorax pale ochreous-yellow; colour of the 
ventral surface ferruginous mottled with black; in the males the 
drums are rather small and do not project on the sides. 
This Cicada does not appear about Sydney every year, but 
during this last season it was comparatively numerous; it is never 
found about the gardens, but I found it more numerous where 
the smooth-stemmed gums ( Eucalyptus sieberiana and E. hcemas- 
toma ) were common, generally upon the main trunk. 
Psaltoda mcerens, Germ. ("The Floury Miller"). 
Expanse of wings inches, width of shoulders 8 lines, length 
of body inches. Wings hyaline, nervures of the fore wings 
black, with the edges of several forming a W near the tip of the 
fore wing, and those forming the apex and sides of the lower row 
of cells edged on either side with black, giving them a thickened
