2. The Occurrence of Heliothis obsoleta (Fabricius) in North 



Queensland (Lep.). 



Early in April, 1912 (April 10), I hastily examined a field 

 of corn near Nelson (Cairns District), North Queensland, 

 Australia, and found it badly infested with the cotton boll- 

 worm of the Southern United States and elsewhere. The 

 injury to the ears was characteristic and such larvae as were 

 found could not be mistaken by one familiar with the young 

 of the species. Several eggs were also found on the silk. The 

 occurrence is worth recording, since the insect, I believe, has 

 never been recorded from this region, though known years 

 since to occur in the southern portions of the state. The 

 caterpillars found were in stadia II and IV. Most of the 

 corn was about half mature, referring to the ears, the plant 

 long since grown. A week later, the insect was observed 

 in another field of Indian corn growing among sugar cane, 

 five miles nearer Cairns. It is well established in North 

 Queensland, evidently, but I did not see it in a cotton field 

 visited for a short while. 



3. Fragments on Icthyura inclusa var. palla (Lep.). 

 Colonies of the caterpillars of this species at Blacksburg, 

 Virginia, were obtained from willow, June 28, 1902. The 

 nests containing a colony usually surrounded two slender 

 twigs with their foliage. The colonies were combined and fed, 

 all in one rearing-cage. On July 9, after several days of ne- 

 glect, all of the caterpillars attempted to pupate, though most 

 were certainly not fullgrown. The action was obviously an 

 adaptive one. The cocoons were constructed between two 

 leaves or else merely in the web of the nest. Very few of the 

 larvae succeeded in changing themselves. On July 19, the 

 moths commenced to appear and they were transferred to 

 another cage in order to mate them. On July 21 a pair were 

 observed mating, the female above, hanging from the top of 

 the cage by her conspicuous fore legs, the male hanging head 

 downward from the tip of the abdomen of the female, the
