Varying in size from upwards of six inches across 

 the wings to nearly four and a half. The sur- 

 face is of a greyish white, with the nervures and 

 posterior horder black ; the latter sinuated inter- 

 nally, and divided by a series of large spots of a 

 whitish colour, and generally an oval shape; be- 

 tween each of the nervures, and beyond the middle 

 of the wing, is a longitudinal bkok stripe: the 

 primary wings are moreover marked rather before 

 the middle with four irregular black spots, the an- 

 terior one on the costa, the other three forming an 

 abbreviated arched band. The under side does not 

 differ materially from the upper, but the black 

 stripes are rather broader, and there is a large irre- 

 gular pateh in the discoidal cell. The body is 

 whitish with a black line along the back, the thorax 

 having two black central lines and two short trans- 

 verse ones at their extremity : the breast is marked 

 with oblique black lines, and a row of dusky points 

 runs along each side of the abdomen: antenna? 

 black. 



The insect is a native of Java, Amboina, and 

 other Asiatic islands.
