Lepidoptera Rhopalocera of Trinidad (1904).

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 little 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 wallacei, 
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 lnk 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 
Heliconius melpomene and perhaps some of its very many 
named forms. 
The bulk of the additions to the list are to be found in 
the EHrycinidae and Hesperidae. Many interesting records 
have been made, however, of some of the larger and more 
conspicuous species, such as Hunica orphise, E. malvina, 
the very rare Dynastor macrosiris, which was taken by 
Sir Gilbert Carter at Government House; the two new 
subspecies of Adelpha, A. phylaca trinita, A. velia trinina,
