“Testa _varicibus_ æqualibus longitudinalibus, &c.” is an incorrect reading of Professor Gmelin. If we examine the Linnæan description of the Museum of the Queen of Sweden, _Mus. Lud. Ulr._ to which Gmelin refers, we shall find it to be as might be naturally expected, “testa _costis_ æqualibus;” for it is the ribs, and not for veins that Linnæus intended. Linnæus refers to the 10th edition of his Systema Naturæ, which is not mentioned by Gmelin, and here we again meet with the same reading “testa _costis_ æqualibus, &c.” We have been the more explicit in pointing out this error, because we observe that one Conchologist, not long since, in the absence, doubtlessly, of the moment, has translated literally the Gmelinian text in describing Buccinum Harpa.

Donovan, Simpkins & Marshall, June 1.^{st} 1822._ ] ------------------------------------------------------------------------ ENTOMOLOGY. PLATE IX. PAPILIO PSAMATHE. PSAMATHE BUTTERFLY. LEPIDOPTERA. GENERIC CHARACTER. Antennæ elevated or thicker towards the tip, and generally terminating in a knob. Wings erect when at rest. Fly by day. * Danai Cand. SPECIFIC CHARACTER AND SYNONYMS. Wings entire, white; tip of the anterior pair black spotted with white, lower ones beneath greenish with two darker bands, the anterior one incurvate. PAPILIO PSAMATHE: alis rotundatis integerrimis albis: anticis apice nigris albo maculatis; posticis subtus virescentibus; fasciis duabus obscurioribus; anteriore incurva. _Fabr. Spec. Ins. T. 3. p. 1. 207._ * * * * * A native of America and nearly allied to Papilio Phronima, represented in plate 153 of the work of Cramer. It differs in having only the tip, and not both the base and tip, black, as in Phronima. Our present species is also distinguished further by having two white spots on the black tip of the anterior wings, in the apex of the anterior wings being destitute of any black spot beneath, and in the anterior band on the lower wings beneath being incurvate. This species has not been represented by any author. Fabricius described it from the drawings of the late Mr. Jones, and it is from that matchless series of designs and MSS. that the present figures are copied. ------------------------------------------------------------------------ [Illustration: _10_ _London.
