and the base of inner margin, the costa being wholly ochreous ; it is also 
the largest species of the group. It most resembles C. diplorrhous and 
C. dicrenellus, but in both of these there is a clear white costal streak. 
Arthur's Pass, from 9,000 to 4,500 feet ; common in January, appearing 
to frequent rather damp places. 
25. Cr. enchophorus, n. sp. 
Male, female.—29—-338 mm. Head white, behind eyes brownish-ochreous, 
centre of face somewhat ochreous. Palpi very long, brownish-ochreous, 
above and internally white. Antenne dark fuscous, in male rather stout, 
dentate, moderately ciliated. Thorax light brownish-ochreous, with a white ' 
. central longitudinal stripe. Abdomen whitish. Legs pale brownish- 
ochreous, posterior pair whitish. Forewings very elongate-triangular, nar- 
row towards base, costa slightly arched, apex round-pointed, hindmargin 
oblique, nearly straight, rounded beneath ; dull light brownish-ochreous ; a 
slender white line immediately beneath costa from base to middle ; veins on 
posterior half of wing suffused with white and obscurely margined with dark 
fuseous; a whitish suffusion towards inner margin throughout, towards 
base defined and margined above with dark fuscous ; a rather narrow nearly 
straight white median streak from base to middle of hindmargin, unevenly 
margined with blackish throughout, posterior half slightly curved upwards ; 
a curved transverse row of black dots towards hindmargin, and a hindmar-

ochreous-tinged. 
Allied to C. callirrhous, in which species the male has similar dentate 
antenne (not mentioned in my description) ; but larger, with white markings 
(except median streak) considerably suffused, whilst C. callirrhous is specially 
characterized by their definiteness ; distinguished also by the posterior and 
hindmarginal rows of black dots, and by the uppermost white line being dis- 
tinctly subcostal, not costal, towards base. | 
Castle Hill, on dry slopes from 2,500 to 4,000 feet, in January ; rather 
common, but apparently local. 
26. Cr. diplorrhous, n. sp. : 
Male, female,.—81-84 mm. Head whitish-ochreous, becoming white on 
crown. Palpi very long, light brownish-ochreous, above and internally 
white. Antenne fuscous, in male subdentate, moderately ciliated. Thorax 
pale ochreous, with a suffused white central stripe. Abdomen whitish. 
Legs light ochreous, tarsi dark fuscous, posterior legs whitish. Forewings 
very elongate-triangular, narrow, not much dilated, costa slightly arched, 
apex round-pointed, hindmargin slightly sinuate, rather oblique, rounded 
beneath ; pale brownish-ochreous, brassy-tinged, towards inner and hind
