the second Australian species has, as I anticipated, been satisfactorily 
proved to be also, like the first, a species of wide range, occurring through 
many Pacific Islands, and consequently not attributable to the true Austra- 
lian fauna, which therefore includes no endemic species of this genus. 
91. Cr. catacaustus, n. sp. 
Male, female.—292-26 mm. Head and thorax dark ochreous-fuscous. 
Palpi rather long, dark fuscous, mixed with greyish-ochreous beneath. 
Antenne dark fuscous, in male very shortly ciliated. Abdomen dark fus- 
cous, hairy beneath towards base. Legs dark fuscous, coxæ densely hairy 
beneath, posterior legs ochreous-whitish. Forewings moderate, We 
posteriorly somewhat dilated, costa slightly arched, apex obese, d 
margin not oblique, rounded beneath ; ochreous-brown, sometimes slight y 
reddish-tinged ; costal edge narrowly whitish-ochreous in male, ochreous- 
white in female, except near apex; a straight moderately broad ochreous- 
white central streak from base to hindmargin slightly above middle, hardly 
narrower at extremities, more or less indented obtusely on both magus " 
little beyond middle, suffusedly margined above and beneath with dark 
fuscous: cilia shining grey, tips white. Hindwings dark grey, posteriorly 
still darker, pectinations grey-whitish ; cilia ochreous-white, with a shining 
grey basal line. 
This species aud C. tritonellus appear to differ from all the other New 
Zealand species of the genus by the hairy coxæ and undersurface of thorax, 
and probably mark the developmental connection with Orocrambus. c. 
catacaustus, although marked quite as in typical species of the genus, hon a 
different superficial appearance from the much stouter build, the forewings 
much broader anteriorly and therefore more oblong, and the deep colourmg, 
especiàlly of the hindwings. 
Arthur's Pass, taken commonly in swampy places at from 8,000 to 
4,000 feet, in January ; flies with much activity. 
22. Cr. tritonellus, n. sp. 
Female.—22 mm. Head ochreous-white. Palpi, thorax, and abdomen 
ochreous-white mixed with dark fuscous; palpi rather long. Antenn® 
whitish-grey. Legs whitish, coxe hairy beneath. Forewings elongate- 
triangular, costa almost straight, apex rounded, hindmargin straight, 
oblique; pale greyish-ochreous, somewhat mixed with fuscous; costal 
edge obscurely whitish, posteriorly rather broadly suffused with whitish ; 
inuer margin narrowly white towards base, margined above by a strong 
dark fuscous streak from base to 4; a rather broad white central streak 
from base to middle of hindmargin, attenuated towards base, margined 
beneath from base to middle with dark fuscons, and cut by a faint 
greyish-ochreous line from near base of upper margin to beyond middle of 
lower margin; veins on posterior half marked with strong dark fuscous
