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, l^ut 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-

PsALTODA MCERENS, Germ. ("The Floury Miller"). 



Expanse of wings 4J inches, width of shoulders 8 lines, length 

 of body H 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
