(3) Chloridea assulta, Guen. 



Appeared at the same time as the last species, and was not 

 seen in any numbers. 



(4) ClRPHIS LOREYI, Dup. 



Not an abundant insect, and strictly confined to a seasonal 

 appearance. Taken in June 1905, and not again until the 

 same month in 1906. 



(5) Prodenia littoralis, Boisd. 



Abundant on all the islands, on the wing most plentifully 

 in May and June. The larva feeds on a multitude of low- 

 growing plants. This very widely distributed species is found 

 on Christmas Island. 



(6) Spodoptera mauritia, Boisd. 



Several specimens were taken in June 1905, but in June 

 1906 it did not appear again. 



(7) Leocyma sericeata, Hmpsn. 



Not abundant ; appears in June and again in November. 

 The larva is pale green and bears a few scattered hairs ; it 

 feeds on the leaves of the Waru {Hibiscus iiliaceus, Linn.). 

 Not on Christmas Island, though its genus is represented by 

 L. tibialis, Fabr. 



(8) Ophiusa coronata, Fabr. 



Only one specimen taken, and a few more seen, in June 

 1905. Occurs on Christmas Island. 



(9) Ophiusa melicerta, Dru. (Plate xxi. Fig. 3.) 



This is one of the most plentiful of the atoll insects, 

 being found wherever the bushes of Pemphis acidula, (native 

 name Kayu burung) are growing. It is on the Y^ing practically 

 all the year round, but is most common from June to Sep- 

 tember. The larva bears a wonderful resemblance to the 

 twigs of the Pemphis acidiila or the Picinus on which it feeds. 

 It has a habit of dropping from its twig when disturbed, but 

 it always manages to get a fresh hold of a lower twig, on the
