(2) CutoripEA opsoLera Fabr. 
No specimens were taken during 1905, and the insect only 
became at all plentiful in June 1906. 
(3) CHLORIDEA AssuLTA Guen. 
Appeared at the same time as the last species, and was not 
seen in any numbers. 
(4) Crrpuis LoREY! 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) PropEnta LirroRALs 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) SpopopreRA MAURITIA Boisd. 
Several specimens were taken in June 1905, but in June 1906 
it did not appear again. 
(7) LeocymaA sERIcEArA 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 Waroo (Hibiscus tiliaceus Linn.). Not on Christmas 
Island, though its genus is represented by Z. tebialis Fabr. 
(8) Opuiusa coronata Fabr. 
Only one specimen taken, and a few more seen, in June 1905. 
Occurs on Christmas Island. 
(9) OpHrusA MELICERTA Dru. 
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 wing practically all the year 
round, but is most common from June to September. The larva 
bears a wonderful resemblance to the twigs of the Pemphis acidula 
or the Ricinus 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 way down, although it appears 
to be falling to the earth. It pupates in a few leaves spun 
together at the ends of the twigs; the pupa is covered with a fine 
bloom. Fourteen days are passed in the pupal state.
