They also appear to have some relation with Erebus. The original specimen here figured is stated by Mr. Drury to have been in the possession of Captain May, of Hammersmith, when the drawing was made. It is now in all probability destroyed, and cannot be traced. THECLA PAN. Plate XXIII. fig. 3, 4. ORDER: Lepidoptera. SECTION: Diurna. FAMILY: Lycænidæ, _Leach_. GENUS. THECLA, _Fabr._ (Syst. Gloss.) Polyommatus p. _Latr._ Papilio (Pleb. rural.), _Linn. &c._ THECLA PAN. Alis fuscis bicaudatis; subtus fuscescentibus, ocellis duobus anguli ani, externo nigro iride rufâ. (Expans. Alar. 1 unc. 3 lin.) SYN. Papilio (Pleb. rur.) Pan, _Drury_, _App. vol._ 2. HABITAT: Jamaica. _Upper Side._ Antennæ black. Thorax, abdomen, and wings dark brown, or dark hair-coloured; the latter being furnished with two small tails like hairs, the extremities being white. _Under Side._ Palpi white. Breast greyish. Wings nearly the same colour as on the upper side. The posterior having two eyes on each at the abdominal corners; one being black with a red iris, the other grey and faint; above them is a small indented white line, pointing to a spot of the same colour placed at the middle of the anterior edge. Fabricius, without referring to this figure of Drury, described an Indian species of the same genus from Drury's collection, under the same specific name, which must of course be rejected. The French encyclopedists consider the latter as identical with the Fabrician Hesperia Isocrates. PLATE XXIV. [Illustration] EREBUS HERCYNA. Plate XXIV. fig. 1, 2. ORDER: Lepidoptera.
