A REVISION OF THE AUSTRALIAN COSSIDAE ( LEPIDOPTERA ) . 49 
3. Catoxophylla cyanauges n.sp. 
Kvavavyrjs, with dark blue sheen. 
$ , 80-90 mm. Head and thorax dark fuscous with dark blue 
sheen; thorax with collar, lateral aspect, and inner edge of tegulae 
white. Palpi dark fuscous, beneath white. Antennae blackish; pec- 
tinations in male 8. Abdomen blackish; on posterior half edges of 
segments and a median line white. Legs dark fuscous. Forewings 
very narrow, costa straight, sinuate beyond middle, apex acute ; 
fuscous with coarse transverse blackish strigulae arranged in longi- 
tudinal rows between veins; some small white dots in apical and 
terminal areas. Hindwings with termen strongly concave, apex very 
acute; dark fuscous becoming blackish in basal and tornal areas; a 
white costal streak to three-fourths; cilia white. 
West Australia : Toodyay in August ; Bencubbin ; two specimens. 
3. Gen. XYLEUTES Hb. 
Verz. p.195. 
Palpi short or moderate, slender, closely appressed to face. 
Antennae of male bipectinate, becoming simple near middle. Thorax 
and abdomen hairy. Tibiae without spurs. Forewings with areole 
long and projecting strongly posteriorly, 7 and 8 stalked, 9 connate or 
stalked with them, 11 from areole near its base, median cell present. 
Hindwings with median cell, all veins separate. Type X. strix Cram, 
from Archipelago and India. 
This large genus is found in the Indomalayan, African, and 
Neotropical regions, but the species are more numerous in Australia 
than elsewhere. Their discrimination is difficult, for they often show 
varietal differences, especially in the development of the markings of 
the forewings. Sexual differences are not uncommon, and the range 
of size in any species may be large. For their identification careful 
and detailed descriptions are necessary, and these must be carefully 
studied. No help would be given by the construction of a key, such 
as is useful in many other cases. 
4. Xyleutes zophospila n.sp. 
£ o(/)og7t iAo?, dark-spotted. 
Head white with an ochreous line between antennae. Palpi one- 
half; fuscous, lower surface white. Antennae white; pectinations in 
male 5, dark fuscous. Thorax white with two pairs of blackish dots; 
small anterior and posterior crests and posterior edge of patagia 
ochreous. Abdomen white; blackish rings with ochreous apices on five 
terminal segments^ tuft ochreous. Forewings narrow, costa slightly 
arched, apex obtusely pointed, termen rounded, oblique ; white 
with numerous blackish spots ; a costal series more or less transversely 
elongate; a similar dorsal series; others irregularly dispersed in disc; 
three obliquely transverse series in lines at three-fourths, subterminal 
and submarginal; a terminal series; cilia white. Hindwings white with 
some blackish spots in apical area only; cilia white. It differs from 
the two following species in the white hindwings. 
West Australia : Edmond Station near Carnarvon in June 
(J. C. Carmody) ; one specimen. Type in Queensland Museum.
