The abnormal appearances thus noticed resolved them- 
selves into three. 
1. The curly and nasty condition of the upper foliage. 
2. Dead strips in the older leaves. 
3. Caterpillars in the developing ears, and the same 
boring into the stems. 
To clear up the matter, I visited a maize field near 
Luggage Point, and carefully inspected a blighted crop. 
Here every stem of maize was perforated by caterpillars, 
and it was clearly evident that, the stalks being bored 
extensively, both below the ears and between them and the 
upper flower, they had spoiled all chance of grain develop- 
ment. I reared a number of the caterpillars from these 
bored stalks as well as some from the abortive ears. 
On April 19th I telegraphed to the secretary of the 
Farmers’ Association at Caboolture, asking him to kindly 
examine if all the blighted maize stalks were perforated by 
boring caterpillars, and received the following reply :— 
‘‘On examining the maize, I find a good many affected with 
the boring caterpillar you speak of. They have been more or less 
prevalent in the late maize crops for years. I do not think they 
have much to do with the rust, with the exception of weakening the 
plant, and which is consequently less able to resistthe rust I find 
that maize that has been well worked and kept perfectly clean, 
although badly rusted, will yet mature a fair cob, but even these 
patches of maize are much lighter than they should be for the 
labour bestowed upon them.—G. W. Mattett, Caboolture, 22nd 
April.” 
As this statement gave me no assistance, 1 asked Mr. 
Price Fletcher, of the Queenslander newspaper, to interro- 
gate the farmers he came in contact with, and the replies 
given to him by a number of intelligent observers were to 
the effect that the caterpillars had extensively bored the 
stems of all the blighted crops. The grubs, which I had 
previously collected at Luggage Point, were kept under 
observation, and on May Ist resolved themselves into 
orange-coloured moths with black spotted wings—the same 
that had been found eating the unripe peaches for several 
seasons past.
