On the occurrence of Cochineal in the Northern United 

 States. — In the northwestern part of Nebraska and the adjacent part of 

 Dakota, are large areas thickly covered with several species of Cactaceae, 

 on which I was surprised to find Cochineal in considerable quantities. As- 

 red paint is a favorite article of use among the Indians, I inquired of sev- 

 eral men who were familiar with the Indians of the plains, both Sioux and 

 Pawnees, if the Indians made use of the cochineal, but none of them had 

 ever seen or heard of its use. 



At that time the fact of the occurrence of this insect in such high lati- 

 tudes was quite new to me, nor have I since seen any statement in print of 

 its occurrence in the United States, except in Southern California, though 

 I have learned from collectors that it is not uncommon in Kansas and 

 southwards. I have therefore thought a brief notice of the fact might be 

 acceptable. 



The occurrence of this insect in such a region suggests a possible indus- 

 try at some future time, when the Great West shall be settled up, as in this 

 region very little can be cultivated, and if cochineal can be produced it 

 may be worth trying. E. P. Austin.
