Or. torrentellus n. $p. 



15" 151". Head ochreous, with a small whitish spot on crown, 

 and a pale line above each eye ; collar whitish. Labial palpi more 

 than twice as long as head, ochreous, at apex fuscous, beneath 

 white towards base ; maxillary palpi ochreous. Antennae 

 fuscous, basal joint ochreous. Thorax ochreous-brown, with a 

 broad silvery-white stripe on each shoulder. Abdomen pale 

 ochreous. Anterior and middle legs fuscous, posterior legs 

 ochreous. Forewings elongate, moderately broad, hardly dilated, 

 hindmargin very oblique, rounded ; very pale ochreous, towards 

 apex and at base suffused with brownish -ochreous, and very 

 slightly on disc ; a very narrow silvery-white costal streak 

 from middle of costa to apex, sometimes produced further 

 towards base, much attenuated at extremities ; very broad 

 straight silvery-white median streak from base to hindmargin, 

 continued also quite through cilia, strongly but irregularly 

 margined on both sides with blackish scales, least distinctly on 

 disc, very broadly and strongly towards apex, especially on upper 

 margin ; sometimes the upper margin of this streak tends 

 slightly to be produced upwards on hindmargin : cilia, except 

 on the white streak, fuscous-grey, with a rather darker parting 

 line. Hindwings white, in ? slightly suffused with greyish 

 towards apex ; cilia white. 



Differs from preceding by the longer palpi, paler colour, and 

 median streak produced through cilia, as well as the absence of 

 any distinct apical tooth ; from allied European species l)y its 

 large size, and the very great breadth of the median streak. 

 Hitherto only from neighbourhood of Duaringa, Queensland ; 

 two specimens in Sydney Museum, sent by Mr. Greo. Barnard.
