This is an inquiry directed to any Lepidoptera taxonomist who might be closely acquainted with the taxonomic works of Frederick Moore who wrote in the 1800's. IN an 1877 paper he refers to wing measurements as "Exp." Does anyone by any chance have sufficient familiarity with Moore's publications to definitively know whether that refers to wingspan or wing length? If so I would be pleased to hear from them.
