presumably represent those which Spinola had before him. One, 
labelled simply “Brasil”, is here designated lectotype of gastricus on 
the basis of the remarks quoted above. Since there are no specimens 
in the Berlin Museum clearly from the Klug or Spinola collections, 
it seems probable that this is the true type. The second specimen, 
labeled “Chili, Gay” has broad temples and clearly belongs to 
chilensis n. sp., while the female from Brazil has narrow temples 
characteristic of gastricus as here interpreted.
