above, and appears much narrower than those preceding 

 it; skin soft, and sufficiently transparent for the 

 working of the internal organs to be seen through it. 

 Ground colour bright pale green, the head with a 

 slight yellow tinge ; dorsal stripe clear white, as are 

 also the narrower subdorsal stripes ; spiracular stripes 

 also white, but having a faint yellowish tinge which is 

 wanting in the other stripes, and above them, in one 

 of the specimens, is an irregularly defined stripe of 

 dark green, which, on the second, third, and fourth 

 segments, takes the form of black streaks ; the large 

 round spiracles are white, enclosing an intensely black 

 spot, and immediately over, but touching each spiracle, 

 is another considerably smaller white spot, which also 

 encloses a minute but equally black dot ; the rather 

 small tubercular spots are white. Ventral surface and 

 pro-legs uniformly light green ; the anterior legs on the 

 outside are black, ringed with whitish. 



In a few days the larvse spun rather loose cocoons 

 under the leaves or moss at the bottom of their cage, 

 and two moths emerged on July 1 9th and 22nd respec- 

 tively. (G. T. Porritt, May 11th, 1889 ; E.M.M., XXV,
