 name tomentosa to a species that he described in contradiction to 

 Linnaeus' " elytris subtomentosis " as having the " elytra in rostro

 description of to'rnentosa with a question. The locality this time 

 was given as " in Africa aequinoctiali " (not, as Harold stated, 

 "America aequinoctiali"). In 1787, Fabricius again published the 

 same short description of glahrata.^ without mentioning Linnaeus'
