ties ; but as this is not the case in any other instance with which
T am acquainted, I do not think it at all probable.
Subfamily THYRETINX.
Autenns always more or less strongly pectinated, more strongly
iri the males than in the females, neuration and coloration fre-
quently partaking of the character of the preceding subfamily ;
aual scgmcnt of the males terminally slightly pilose.
Genus HYDI~USA, Walker.
This genus is most nenrly allied to Syntomio, the antenns of
the males in thc typical group being armed with rather short
pectinations, aud the females with mere serrations.
1. IIYDRUSA CINGULATA, n. sp.
Nearly allied to H. annulnta, but smaller, the head narrower, of a
brighter orange colour, the crvst more narrowly banded with orange ;
primaries with the spot at end of eel1 smaller, narrower than long,
the subapical spot bifid, much more elongated, the discal bifid rpot
subtriangular, no pale tawny dot connecting the discal and subapica
spots ; secondaries with tlie base more narrowly orange (the orange
area only occupying the brsal third of the wing), discal oval spot
smaller, less distinctly divided : body below brighter in colour, abdomen
banded with orange down to the anus ; wings below nearly as
above : espnse of wings 37 millims.
Moreton Hay (Gihbons). Type, B.M.
The type of H. annulafa is in the Baoksian cabinet, and agrees
with an oxampla which we have from Sidney.
We have two examples, registered “ N. E. coast of Australia,”
which scem to be referable to If. cingulafa.
1. 11. IIUMERALIS, n. sp.
Allied to the preceding species, but smaller; head orange, with a furrate
spot on the crest ; thorax blackish, tegulae orange ; abdomen orange,
the segments edged with blark ; primaries as in the preceding spe-
cies; secondaries with the basal half pale orange, apical half blark-
brown, a large bitid subapical pale orange spot scarcely separated from
the basal area : wings below as above ; expanse 2!) millims.
N. Australia (Elsy). Type, B.M.
3, 11. NIGIIICEPS, n. sp.
Nearly nlliecl to 11. annalata, same size and general appearance ; head
entirely black above, frons oranxe ; thorax black, abdomen blnck nar-
rowly hHntlrd nitli ornngr : mlllFS blrck, spotted with pale tnany
