The utility of the kelep will depend, therefore, upon the answer of 
the remaining question, whether the kelep can survive and multiply 
under conditions of climate, soil, and food supply to be found in the 
United States. In structure, habits, and instincts it is wonderfully 
adapted to the work of destroying the cotton boll weevil. 
It is, in short, a new and efficient insectivorous animal, in all prob- 
ability capable of being utilized for the protection of cotton and other 
crops In many tropical and subtropical regions, whatever may be 
the results of the present effort to naturalize it in Texas. 
It is still impossible to predict the fate, in a new country, of an 
insect which has so recently become an object of scientific study, but 
whatever the experiments may ultimately show regarding its ability 
to become established and thrive in the United States, it seems certain 
that the social organization of the species does net disqualify it for a 
future of agricultural utility. To prejudge its prospects by refer- 
ence to the habits of the true ants would be the same kind of error as 
to discredit the honeybee on the ground that the bumblebees and 
wasps are worthless and undesirable insects. 
Recent advices from Texas, received just as this paper is being com- 
pleted, seem to indicate that the colonies which have been left out in 
the open ground of the cotton fields, without care or food, will not 
survive the winter, though they have lived long enough to show that 
low temperature alone is not fatal, thus confirming the result of a 
cold-storage experiment made in Washington last August (1904). As 
already explained in the present paper, the colonies of the first 
importation were far too small to make the experiment a fair one, 
and they were planted in Texas after the middle of July (1904), 
much too late in the season. A knowledge of the social organization 
of the insect will permit these and other obstacles to be avoided in the 
importations to be made in the coming spring (1905), and it is hoped 
that a satisfactory and conclusive test will result.
