Noctuidae Catocalinae — VlETTE 
141 
part of the wing is dark, only the apex and 
the costal area are really reddish brown. 
The posterior wings are blackish brown 
with purple tracings, which include a medial 
spot, a spot in the middle of the abdominal 
edge, a submarginal band, and a very narrow 
marginal band between Cun, and A 2 . 
The underside is lighter than the upper 
side. The anterior wings have an indication 
of a dark, transverse band edged with gray. 
The posterior wings have the tracings of the 
upperside well marked. The underside of the 
body is a dirty white. 
Genitalia c T : (Fig. la). The tergite of 
the sixth urite has a middle plate which is 
striped transversely (Fig. lb). The tegumen 
is not much developed dorsally but carries 
laterally large processes which are suddenly 
thinned at their apex and end in a well- 
sclerotized and strongly colored point; the 
uncus is directed downward, it is hairy and 
sharp at its extremity; a scaphium is present; 
the vinculum is not much developed; the 
valvae are long, widened at the end; a small 
angular process is present about the middle 
of the dorsal edge of the sacculus; the juxta 
has almost the shape of a V; the penis is 
asymmetrical without cornuti. 
Genitalia 9 : (Fig. 1 c). Simple, the lobes 
of the oviporus are normal, with posterior 
apophyses; the eighth urite is unsclerotized 
in the medioventral area; the anterior apo- 
physes are present; the ostium bursae is mem- 
branous as is the bursa copulatrix and the 
ductus bursae; the bursa copulatrix is orna- 
mented with unsclerotized folds. 
New Caledonia ( Layard ) : Pouerihouen 
(Quod), Canala (Delacour), Baraoua (Ca- 
tala). 
Loyalty Islands: Lifu (Whitmei). 
New Hebrides (Mathew). 
The species extends from India to Fiji and 
Samoa. 
Genus Phyllodes Boisduval 
Phyllodes Boisduval, 1832, in Dumont d’- 
Urville, Voyage de FAstrolabe, Lepid. 1: 
246; Hampson, 1913, Cat. Lepid. Phal. 
B.M. 12: 389; Gaede, 1938, in Seitz 11: 
470 (type conspicillator Cr.) . 
The proboscis is fully developed; the labial 
palpi are upturned; the second joint strongly 
widened, spatulate; the third joint small, 
normal, and dilated at its apex; the frons is 
smooth with a thick tuft of hairs; the anten- 
nae are filiform, reaching the middle of the 
costa. The thorax is clothed with hairs, with- 
out crest; the anterior wings have a strongly 
arched costa and the apex is slightly pro- 
jected; in the posterior wings the medial cell 
does not extend as much as one third of the 
wing. 
Only one species is of interest here.

Wingspread 159-175 mm.; length of the 
anterior wings 78-80 mm. 
This is one of the most beautiful and larg- 
est of the moths from New Caledonia and 
the New Hebrides. The head, the thorax, 
and the abdomen are abundantly clothed 
with reddish gray hairs, with a light purple 
tint on the head, the patagiae, the inferior 
edge of the tegulae, and the abdomen. 
The anterior wings are very wide, with the 
external margin and the inferior edge de- 
scribing an arc of a circle; the costa is strongly 
arched in its apical part and the apex is 
slightly projected. The background color is 
rusty brown, more or less dark according to 
the specimens, with the variable tracings
