APOROPRYLA AUSTRALIS. 65 



most gaily coloured of the Noctux, is one inch and five- 

 eighths in length, rather stout and cylindrical, slightly 

 tapered towards the anal tip. 



The ground colour is now a very brilliant yellow- 

 green, or, in some individuals, greenish-yellow; the 

 head green, freckled with reddish ; a red unpolished 

 semicircular plate on the back of the second segment. 

 On the back of each of the other segments is a red 

 diamond, the front part of which for about a third of 

 its length is black, through which runs the flesh- 

 coloured or pale pinkish dorsal line, edged with red, 

 thus cutting what would be a black triangle into two 

 black wedges pointing forwards. In the centre and 

 sometimes in the hinder portions of the red diamonds 

 the dorsal line often becomes suffused with their colour. 

 The subdorsal line black, but only at the beginning of 

 each segment. The spiracles white, placed in semi- 

 circles of black, and the space between them and the 

 subdorsal line thickly freckled and streaked with deep 

 red, appearing like a broad band of red along the side ; 

 the subspiracular stripe very pale primrose-yellow, its 

 lower edge softened a little into the ground colour, and 

 followed below by a blotch of red or pinkish on each 

 segment ; the prolegs tipped with the same colour ; the 

 ventral surface pale yellowish-green. 



Yar. 1. The ground colour a rather deep reddish- 

 pink on the back and sides. The freckled side band 

 and dorsal diamonds of darker purplish-red, with all the 

 other details as in the preceding. 



Yar. 2. Ground colour of the whole surface olive- 

 green, but appearing on the back only at the beginning 

 of each segment as a transverse narrow band, in which 

 can be seen the pinkish- white dorsal line and the black 

 wedges, though much shortened ; the rest of each seg- 

 ment is covered by a broad, transverse, dark purplish- 

 brown band extending to the spiracular region and 

 hiding all other marks, each white spiracle in a large 

 black blotch connected with a narrower blackish- 

 brown transverse band on the ventral surface of each
