The family of _Nymphalidæ_ is the sub-typical group of the diurnal Lepidoptera, forming our tribe _Papiliones_. In its own circle it therefore represents the _Feræ_ among quadrupeds, the _Raptores_ among birds, the _Aptera_ among annulose animals, and the _Scolopendridæ_ in the order _Myriapoda_. The analogical representations resulting from this view of the subject are innumerable. * * * * * * [Illustration: TERACOLUS _Sub-fasciatus_.] TERACOLUS sub-fasciatus, _Burchells Yellow._ ---- Family Papilionidæ. Sub-family Colianæ. Genus (?). Teracolus _Nob._ GENERIC CHARACTERS. Antennæ with the club abrupt, and more or less compressed anterior wings trigonal, posterior rounded; Palpi as in _Colias_, but the scales intermixed with hairs. ---- SPECIFIC CHARACTER. _Anterior wings pale yellow, with a terminal orange spot, margined externally with brown, and internally by a short black bar; areola with a black dot; posterior wings yellowish white, both beneath immaculate._ ---- Mr. Burchell was the first who discovered this unpublished species in the interior of Southern Africa, and by his kindness we are enabled to illustrate it. His specimens, unfortunately, are not in the best condition, for he was obliged to preserve many of his insects in books; and these, having been among the number, may probably have had the antennæ more compressed than they were in nature. The form of this butterfly, nevertheless, is perfectly distinct from _Colias_, as may be seen by comparing the nerves of the anterior wings, here given in outline. Not having completed our analysis of the _Colianæ_, we cannot speak with any confidence on the rank or the station of this type; we are inclined to believe it is a _genus_ between those of Colias and Terias, connecting this sub-family with the _Licininæ_. It may, however, be one of the sub-genera of _Colias_, in which case the genus, which it would then represent, is unknown. Fig. 1. represents the anterior wing of _Teracolus_, 2, of _Terias_, and 3, of _Colias_. * * * * * * [Illustration: HELEONA _Fenestrata_.] HELEONA fenestrata, _Australian Burnet_. ---- Tribe Sphingides. Family Anthoceridæ. Sw. (Zyganidæ Auct.) Genus ----? SUB-GENERIC CHARACTERS. Anterior Wings papilioniform, i. e. the exterior margin as long, or longer, than that of the posterior; inferior wings lengthened perpendicularly, but short and rounded; Antennæ pectinate in both sexes. Type _Phalæna militaris_. Lin. Don. _Ins. of China_. pl. 43. ---- SPECIFIC CHARACTER. _Wings hyaline, clouded with irregular waved bars of blue; body, thorax, and macular band round the margin of the inferior wings, orange._ ----
