IX. On the Pyralidina of the Hawaiian Islands. 
By HE. Meyricx, B.A., F.E.S. 
[Read May 2nd, 1888.] 
I am indebted to the Rey. T. Blackburn for the material 
which forms the subject of this paper. He has been 
good enough to make over to me the bulk of the col- 
lection of Heterocera formed by him during six years’ 
residence in the Hawaiian Islands, and the exceptional 
position of these islands renders the accurate knowledge 
of their fauna a subject of great interest. Many of the 
species have, indeed, been described by Mr. A. G. 
Butler, but his work has not been of a character to 
throw much light upon their systematic classification 
and affinities. I am bound to add that, after com- 
parison of the named types in the British Museum with 
the descriptions drawn from them, I find the latter 
frequently so inaccurate that Iam unable to reconcile 
the differences. I have therefore found it necessary to 
re-describe all species not sufficiently described elsewhere. 
Mr. Blackburn furnished me with no notes on any of the 
species, and I have therefore added nothing on this 
head, except in the case of those few insects which I 
took myself during a day spent at Honolulu some years 
ago. ‘The following remarks are a summary of the 
results obtained for this group on the questions of 
development and geographical distribution. 
Of Hawaiian Pyralidina, 56 species are at present 
known. Of these the genera Asopia, Zinckenia, Hro- 
mene, Ephestia, and Achroa, including 7 species in all, 
have undoubtedly been introduced through the direct 
agency of man in recent times, and form no part of the 
native fauna. The single species of Paraponyx, though 
apparently unlikely of introduction, is extremely widely 
distributed, and, as hereafter explained, probably entered 
in the same way. Platyptilia cosmodactyla is probably 
also imported. The remaining 47 are, so far as is
