The specimens were collected from December to March, and in 

 June and July. Most of the Euploeines were obtained from January 

 to March, as also the Hypolimnas. 



Danais plexippus kyllene Fruh. (pi. IVa, fig. 2) and Cethosia 

 cydippe insulata Butl. (pi. IVa, fig. 1). 



The resemblance between these two species already noticed is very 

 striking and is interesting on account of the development of white 

 coloration. The white area is confined to a large apical patch on the 

 fore wing ; in both species this patch is larger than it is in any other 

 form of the two genera, excepting in the Danais form laratensis Butl. 

 inhabiting Tenimber, and here the patch is a little larger. There is no 

 mimic of this Danais in Tenimber. It is curious that Cethosia cydippe 

 should be absent from Tenimber, although ranging to Australia and the 

 Bismarck Islands. If it existed before the coming of the Danais, 

 which is a western species, it may have died out. The presence of the
