herbage it has closely imitated. The male, on the other hand, 

 flies strongly and is not often seen fluttering near to the 

 ground. 



(5) Vanessa Keeshawi, McCoy. (Australian.) 



Only four examples of this species were met with in fifteen 

 months, and since all were observed between May 15 and 

 17, 1906, it is probable that they were waifs. Two rather 

 worn specimens only were captured on Pulu Tikus. 



(6) Danais (LiMNAS) CHRYSiPPUS PETiLiA, Stoll. (Australian 

 and Christmas Island.) (Plate xxi. Fig. 2.) 



Common on Pulu Luar and Pulu Tikus, but not so often 

 met with on the other islands. The larva is pale green, 

 banded with yelloAV and black. The food-plant is Asde2nas 

 curassavica. The pupa is suspended by the tail, and is pale 

 green or buff with small golden dots. The average stay in the 

 pupa is only 135 hours.

Arctiad^. 



(1) Utethesa pulchelloides, Hmpsn. 



A very abundant insect on all the islands. It mostly 

 frequents the seaward side, for there the food-plant, Tournefortia 

 argentea, Linn., lives most luxuriantly. The perfect insect, and 

 the larvae, are to be seen at all times of the year, and season 

 appears to make no difference to its numbers. 



NOCTUID^. 



(2) Chloride A obsoleta, Fabr. 



No specimens were taken during 1905, and the insect only 

 became at all plentiful in June 1906.
