From the very close analogy that prevails between this and several other species of the same tribe, it would, no doubt, have been a matter of considerable difficulty at this time to determine the Fabrician species Papilio Hippodamia with precision, if we had not possessed the means of reference to the Fabrician manuscripts, and the drawings in which it is delineated; for it has remained to this period unfigured by any author. It will be observed that Fabricius does not refer for this species to the Collectanea of Mr. Jones, as in many other instances. The cause of this omission will admit of a very easy explanation; Fabricius had seen the insect in the first instance in the cabinet of M. Mauduit, at Paris, to which he has referred. But subsequently when in England he found a drawing of the insect in the collection of Mr. Jones, and inscribed the name and character of the species upon the drawing, as it afterwards appeared in his Entomologia Systematica; and it is upon this authority that we are enabled to speak with certainty upon a species which, but for this circumstance, would be now involved in ambiguity. The figures in our plate are copied from the drawings of Mr. Jones, inscribed with the hand-writing of Fabricius. At the time Fabricius described this species its _habitat_ was unknown: we have lately met with it in a collection of Brasilian insects, and entertain no doubt of its having been brought with the rest from that part of the globe. ------------------------------------------------------------------------ [Illustration: _32_ _London.
