272 Dr. G. B. Longstaff on It should be noted that the specimens bear particulars as to the localities and exact dates of capture; but at present I have no information as to the circumstances under which they were taken, or the plants with which they were associated.

The first thing that struck me on looking at the collection was that it bore internal evidence of being a fair sample of the fauna,* inasmuch as, among others, such a comparatively obscure insect as Pinacopteryx venata was represented by a series of nine specimens, as compared with four Danaida chrysippus, one Teracolus proiomedia and one Terias brigitta. On the other hand, that the collector had not confined his attentions to the more sluggish insects was proved by the presence of six Eronia leda.

The collection had been previously critically examined by my friends, Dr. F. A. Dixey Pierinae, Dr. H. Eltringham Nymphalidae, and Mr. G. T. Bethune-Baker Lycaenidae and Hesperiidae, who all very kindly placed their notes at my disposal.

In order to make the comparison of the two papers as easy as possible, I have dealt with the insects in the same order as in the paper referred to. Each species has a serial number, the same in the two papers ; where a species occurs in this paper not dealt with in the first, letters are added to the last numeral, la, lb, etc., the interpolated species being put in what seemed to be suitable places.

The very numerous quotations from these three authorities, as well as those from Mr. Willis's letters are within inverted commas. The old plate of the map in the earlier paper has been used again with a few additions.
