USCAPEM INDIANS. The Uscapem (Iscapan) Indians, who were probably Coahuiltecans, lived on the lower Rio Grande. In the middle eighteenth century their main settlements were east of Reynosa, Tamaulipas. They also foraged and camped on the Texas side of the river, particularly in the area of Cameron and Hidalgo counties.
