( 545 ) XXII. Additions and corrections to my Catalogne of the Lepidoptera Rhopalocera of Trinidad (1904). By W. J. Kaye, F.E.S. [Read October 1st, 1913.] Plate XXX. Ten years have nearly elapsed since I published in the Transactions of this Society for 1904 (pp. 159-231), " A catalogue of the Lepidoptera Rhopalocera of Trinidad." In that interval a very large number of additional records have been made, over one hundred and forty fresh species being now added to the list, bringing the total up to four hundred and thirty species. Large as this number is, there will doubtless be some additions yet to be made especially from the southern end of the Island, which has been very httle explored entomologically. Many interest-ing forms remain probably to be discovered in this southern district with its totally different climate to the northern side of the Island. Many of the species found there are not to be taken in the north, such as Heliconius ivaUacei, Heliconius antiochus alba, Papilio sesostris, Papilio belus varus, Helicopis cupido and several others, all of which belong to the Guiana region. It is possible that some intermediate forms, especially in the genus Heliconius, will be discovered which will link up some Venezuelan forms with those of Guiana. Heliconius antiochus salvinii might be expected to occur with the yellow band in the hind-wing in a transitional stage, for the subspecies is an inhabitant of the lower Orinoco. In the dense shore forest of the south coast one might certainly meet with true Heliconiiis melpomene and perhaps some of its very many named forms. The bulk of the additions to the hst are to be found in the Erycinidae and Hesperidae. Many interesting records have been made, however, of some of the larger and more conspicuous species, such as Eunica orphise, E. malvina, the very rare Dynaslor macrosiris, which was taken by Sir Gilbert Carter at Government House; the two new subspecies of Adelpha, A. phylaca trinita, A. velia trinina, TRANS.
