ing rice bran were covered in places with a thin layer of webs and many 
cocoons were seen around the edges of sacks and in folds of the cloth. The 
larvee had not penetrated more than half an inch into the contents. In a flour 
mill here several partly filled barrels of old corn bran had been infested for 
some time, and the surface material was covered by a layer of hulls and 
matted webs about 2 inches thick, beneath which the larvee did not seem to 
penetrate. They were also found on bags of cottonseed meal and rice bran on 
one of the wharves and in the cracks between the planks at one of the docks 
at New Orleans, La., where they were feeding on the cottonseed meal held by 
cotton lint. 
The adults have been frequently seen mating or at rest in any convenient 
position upon sacks and in other situations in mills and elsewhere. Adults at 
rest have the front edges of the wings curved slightly inward and the wings in 
general held closely around the body instead of spread slightly and flattened 
upon their resting place as with Hphestia kuehniella and especially Plodia 
interpunctella, The moth is rather slow in flight. It remains at rest practically 
continuously during the day unless disturbed, but has often been seen flying in 
dark parts of buildings and at evening. 
LIST OF FOOD MATERIALS. 
In time, as observers become familiarized with this moth, it will 
doubtless be found to have nearly the same omnivorous tastes as the 
Indian-meal moth. The following list of its observed food materials 
is appended : 
Cacao beans or chocolate nuts (7heobroma cacao) ; prepared choco- 
late; tonka beans (Dipteryx odorata); English walnuts, or, more 
properly speaking, Persian walnuts (Juglans regia); pecans; pea- 
nuts or ground nuts (Arachis hypogea) ; figs; chick-pea (Cicer arie- 
tinum) ; wheat flour; rice and rice preparations and bran; Indian 
corn and corn meal and other preparations; hominy; oatmeal; cotton 
seed and meal and cotton-oil cakes; asparagus berries; evaporated 
and dried apples; linseed or flaxseed meal; Corinthian currants (Vitis 
corinthiacw) ; the seeds of Zizyphus jujuba; the fruit of Cecropia 
paulmata; “locust beans” of commerce; wild gallnuts; and dried 
insects. 
Taken all in all, it seemed at one time that it was as an enemy of 
chocolate that this species was most entitled to serious consideration. 
Cacao beans are injured seriously. The beans are often badly dam- 
aged and webbed together with silk and covered with excrement and 
other detritus. Again, a bean may have no visible signs of insect 
work upon it other than the presence of a little hole, sometimes nearly 
closed with silk, but such infested seeds are invaribly lighter in 
weight and when opened are found to be filled with more or less 
webbed-up excrementitious matter which can not be otherwise than 
deleterious when taken as food into the human system. Great quan- 
tities of cacao beans are consumed in the form of confectionery and 
in cake, ice cream, and soda water, and in the beverages called cocoa
