This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1886 edition. Excerpt: ...the cell; submarginal spots black and white. Under surface as in S. achatina. Expanse of wings 56 millim. Shillong, Assam. Nyctipao exterior.
