Type data. — Perty originally reported the type (now in the Zoo- 

 logisches Museum, Munich) as "Habitat in Provincia Piauhiensis," 

 Brazil. 



Discussion. — Costa Lmia (1940) reported that this species damaged 

 tomatoes and pimentos in Argentina and was of economic importance 

 in Brazil, 



Personal examination of Perty's type has left no doubt in the 

 author's mind that this is the correct application of the name castaneus. 

 The literature records for specimens from Cuba, Trinidad, and 

 Venezuela are certainly questionable, and in the present paper such 

 specimens have been transferred to divergens, new species.
