Between the specimens caught in the wet and in the dry season no difference 

 is to be observed. 



It is a quarrelsome animal, the cf at least ; I once saw such a butterfly chase 

 away a big Xylocapa from a flower and pursue it in its flight and attack it several 

 times. Once I was also in the opportunity to observe the copulation. When the ^ 

 had been flying for some time around the 9 which sat on a leaf with closed wings, 

 this latter one flew up and sat down again in the same position on another 

 leaf Then the cf sat down beside the $, also with closed wings after which 

 both sideways stretched forth to each other the tip of the abdomen and thus 

 the copulation came about. Then the butterflies flew up united and sat down 

 again on a leaf at some distance. 



The caterpillar is gold-coloured or more or less dark orange, from each 

 segment project on the back two long white or yellow subdorsal hairs, and on 

 the sides there is a small bundle of the same short hairs. Head, anal segment 

 and prolegs black. It is much attacked by Tachiinae. It feeds on the leaves 

 of the already mentioned plant Loranthus Pentandrus L. and is for this 

 reason also often found on all sorts of plants, on which the Loranthus lives 

 as a parasite, which has led to the erroneous belief that it eats those leaves ; 

 the pupae also are sometimes found fastened against the under-side of such 

 leaves. The young caterpillars are pale yellow with a black head and gnaw 

 the surface only of a Loranthus leaf, beginning at the point and ending at 

 the stem, while their excrements remain lying on the part which has been 

 gnawed already. First they are pressed close together, but as soon as the 

 leaf is broad enough, they march in line, the black heads showing in this way 

 as a black streak. 



The chrysalides have the Pieris form and are more or less bright yellow 

 with black dots, especially on the numerous appendages and at the extremity ; 

 most times there is also a black streak on the wing-cases. In consequence of 

 the great difference in the quantity of the black on the pupae in which the 

 separate spots seem to turn little by little into a general black colour, we may 

 suppose that here also It is a question of colour-evolution in which a suchlike 

 increase of the black pigment is a normal phenomenon. The evidently constant 

 direction which reveals itself in this, and the great difference between the 

 minimum and the maximum in that accretion, do not permit us to consider 

 this a matter of variation only. One may compare what is going to be said 

 about the caterpillars of Callidryas Pomona F. 



The head of the chrysalis ends in a nail-like projection. On it are still to 

 be seen a subdorsal row of short spines; the foremost pair of these which 

 are also the smallest, are just on the edge between thorax and abdomen.
