bushes in Piilii Tikiis, but I did not meet with them on any 

 other islands. 



Sphingid^. 



(14) Macroglossa pass ALUS, Dru. 



By no means common, and more frequently seen as a larva 

 than as an imago. On the wing in September. Larva green, 

 with fine bright pink side-stripes ; feeds on Morinda citrifolia, 

 Linn., native name Mngkudu. The pupa is a mottled yellowish 

 brown. 



(15) Cephonodes hylas, Linn. (Plate xxi. Fig. 4.) 

 Common on Pulu Tikus, but not often seen on the Southern 



islands. Frequents the flowers of the Papaia by day, and is 

 evidently the source of the error that bees are common in the 

 islets. When hovering in front of the food-plant, in the act of 

 laying its eggs on the leaves, the long hairs of the extremity 

 of the body stand out like a fan. Most abundant in June and 

 September, but stragglers may be taken in almost any month. 

 Larva feeds on the leaves of Guettarda speciosa, Linn., native 

 name Melati. When first hatched they are quite black, and 

 they only become green in their penultimate and ultimate 

 skins. They are subject to endless variation, and if bred in the 

 dark, very striking larvae, coloured yellow and black, can be 

 produced ; the imagines resulting from these larvae are normal. 

 This insect occurs on Christmas Island. 



(16) Herse convolvuli, Linn. (Plate xxi. Fig. 5.) 



Not a very common insect. Found most plentifully on 

 Pulu Selma. The larva is either green or brown, and it feeds 

 on Convolvulus parviflorus, Vahl. In the atoll this is the moth 

 specially named Bama rama, although in the Straits that word 

 is the general name for all moths. 



(17) Ch^rocampa vigil, Guer. (Plate xxl Fig. 6.) 



The perfect insect is rarely seen, but the larva is very 

 abundant in September. It feeds on the leaves of Pisonia
