Perigonia lusca, the half-blind sphinx or coffee sphinx, is a moth of the family Sphingidae. It was first described by Johan Christian Fabricius in 1777.

Distribution: It is found from the northern tip of South America, through most of Central America, and northward to Florida in the United States.

 The wingspan is 55–65 mm.
