These records were obtained in an open-air insect ary at Honolulu. 
The moths were confined in open-wire cages, which contained an 
inch or more of moistened, sterilized soil. Beet or Amaranthus 
leaves, upon which the eggs were to be deposited, were placed in the 
cages and food was supplied the moths by putting in wads of ab- 
sorbent cotton, which had been saturated in molasses and water. 
This food was evidently greatly relished. The moths were very 
" wild " and flew about very actively whenever the cages were ap- 
proached. Copulation evidently took place at night, as during the 
several months that the species was kept under daily observation, in 
the insectary and field, no mating pairs were observed. Owing to the 
failure to obtain mating pairs and to the fact that it is difficult to 
distinguish the sexes when the moths are fluttering wildly about in 
the cages, no individual egg-laying records were obtained. In one 
case three newly, emerged and unfertilized female moths were placed 
in a cage and supplied with molasses as food. They livecl 10 days, 
and during this time deposited 300 eggs. Such *a record is not con- 
clusive, but it indicates that each female is capable of depositing at 
least 100 eggs. This is doubtless far short of the actual number of 
eggs that one female could deposit under normal conditions.
