10 MR. A. G. BUTLER ON NEW [Jan. 5, 
yellow streak of abdomen replaced by a beautifully shaded, apparently 
overlapping, series of pyriform yellow and orange spots ; wings below 
altogether redder, the dark areas more restricted and paler, the yel- 
lowish markings less vivid, and varied with red; palpi, prothorax, 
and sides of abdomen irrorated with red. Expanse of wings 3 inches 
4 to 6 lines. 
Haiti (Tweedie). Type, B.M. 
Easily distinguished at a glance by the colouring of the abdomen. 
19, CHHROCAMPA IGNEA, n. sp. (Plate I. fig. 4.) 
@. Allied to C. scrofa, but primaries and body dull reddish 
chocolate instead of blackish grey ; primaries with all the markings 
less prominent ; wings below bright reddish all over instead of only 
on basal half of primaries, the outer margins broadly clouded with 
brownish ; body red-brown instead of greyish; palpi and legs varied 
with white, as in C. scrofa. Expanse of wings 2 inches 8 lines. 
Moreton Bay (Gibbons). Type, B.M. 
Although nearly allied to C. serofa, I believe that this species 
will prove to be constant and therefore distinct; I consider the 
most important difference to be the coloration of the under surface 
of the primaries. 
Genus AMBULYX, Walker. 
20. AMBULYX MOoREI (Boisduval, MS.). 
Q@. Primaries above dark clay-colour; outer margin broadly 
brownish, bordered internally by a diffused ochreous line deeper 
externally than internally, becoming silver-grey towards apex, and 
limited on internal margin by a brown spot (decreasing upwards, 
excavated on both sides), and on second and third median branches 
by indistinct brown dots; a nebulous, oblique, pale brownish sub- 
apical streak ; several very ill-defined, sinuated, transverse, ochreous 
lines across and beyond the cell; a geminate, grey, white-pupilled 
discocellular spot ; secondaries testaceous, clouded with clay-colour, 
especially towards anal angle; costa and abdominal margin creamy ; 
a greyish streak across the end of the cell ; an arched discal series of 
six red-brown lunate spots; outer margin red-brown: body bright 
clay-coloured ; crest, metathorax, and a bar across pterygodes red- 
brown: wings below ochreous, becoming tawny externally ; primaries 
with the outer margin grey, with a white external and brown internal 
line ; an indistinct discocellular brown litura; several very indistinct 
brownish transverse lines beyond the cell; secondaries with the outer 
margin brown ; an indistinct discocellular litura and sevaral ill-defined 
spots beyond the cell pale brown; body below bright ochreous, 
becoming tawny towards head. Expanse of wings 3 inches 11 lines. 
Java (Horsfield). Type, B.M. 
Most like A. strigilis in appearance. 
21. AMBULYX MARGINATA, 0. sp. 
Primaries above whity brown, with a pink tinge; base, two
