the second Australian species lias, 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. 

 21. Cr. catacaustus, n. sp. 



Male, female. — 22-26 mm. Head and thorax dark ochreous-fuscous. 

 Palpi rather long, dark fuscous, mixed with greyish-ocbreous beneath. 

 Antennas dark fuscous, in male very shortly ciliated. Abdomen dark fus- 

 cous, hairy beneath towards base. Legs dark fuscous, coxaa densely hairy 

 beneath, posterior legs ochreous-whitish. Forewings moderate, oblong, 

 posteriorly somewhat dilated, costa slightly arched, apex obtuse, hind- 

 margin not oblique, rounded beneath ; ochreous-brown, sometimes slightly 

 reddish-tinged ; costal edge narrowly whitish-ochreous in male, ochreous- 

 white in female, except near apex ; a straight moderately broad ochreous- 

 whife central streak from base to hindmargin slightly above middle, hardly 

 narrower at extremities, more or less indented obtusely on both margins a 

 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 and G. tritonellus appear to differ from all the other New 

 Zealand species of the genus by the hairy coxae and undersurface of thorax, 

 and probably mark the developmental connection with Orocfambus. C. 

 catacaustus, although marked quite as in typical species of the genus, has a 

 different superficial appearance from the much stouter build, the forewings 

 much broader anteriorly and therefore more oblong, and the deep colouring, 

 especially of the hindwings. 



Arthur's Pass, taken commonly in swampy places at from 3,000 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. Antennae 

 whitish-grey. Legs whitish, coxae hairy beneath. Forewings elongate- 

 triangular, costa almost straight, apex rounded, hindmargin straight, 

 oblique ; pale greyish-ocbreous, 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 J ; a rather broad white central streak 

 from base to middle of hindmargin, attenuated towards base, margined 

 beneath from base to middle with dark fuscous, 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
