I just got an email announcing a couple of scholarship opportunities. They do not apply to Spanish or Portuguese majors specifically, but do apply to those of you who have a secondary major with SBS:

Cole Undergraduate Research Award
Supports an undergraduate student who is working as research assistant
with a UMass Amherst faculty member in the College of Social and
Behavioral Sciences, preference goes to candidates who are conducting
original research that has the potential to address current social
problems.

SBS Spring Study Abroad Award
Provides approximately 20 scholarships to SBS undergraduate students
who plan to study abroad in Spring 2014. Average award = $1,000
