The ochraceous hue of this species is brightest on the body and on 

 the basal part of the wings. 



Moreton Bay. 



38. MIGRATTACUS LEBEDOiDES. Mas. Cinereo-ferrugineus, ro- 

 bustus, antennis late pectinatis, abdomine lanceolate basi riigro alas 

 posticas superante fasciculo apicali longo, pedibus validis pilis longis 

 dense vestitis, alis linea submarginali cinerea subundulata, alis anticis 

 falcatis linea postmedia ferruginea obliqua subrecta, lineis nonnullis 

 ferrugineis indistinctis spatio marginali antico nigro margine exteriore 

 undulato, alis posticis latis abbreviates. 



Male. Cinereous-ferrugineous, stout. Antennae broadly pectinated. 

 Abdomen tapering, black at the base, extending somewhat beyond the 

 hind wings ; apical tuft long. Legs stout, densely clothed with long 

 hairs. Wings with a cinereous slightly undulating submarginal 

 line. Fore wings strongly falcate ; an oblique ferruginous post- 

 medial nearly straight line, which diverges from the submarginal 

 line to which it is approximate on the costa; some indistinct interior 

 ferruginous lines ; space along the fore part of the exterior border 

 black ; exterior border slightly undulating. Wings beneath with two 

 postmedial oblique hardly undulating brown lines. Hind wings broad, 

 short. Length of the body 10 lines ; of the wings 20 lines. 



39. DIRPHIA SEXFASCIATA. Mas. Fulva, antennis pallide citrinis 

 subpectinatis, thorace pilis pallidioribus longis erectis dense vestito, 

 abdomine ochraceo cylindrico atro sexfasciato fasciculo apicali longo 

 spisso, pedibus nigris rufescente dense pilosis, alis subhyalinis fusco 

 venosis striga discoidali fusca, alis anticis linea exteriore albida obliqua 

 fusco marginata. 



Male. Tawny. Antennae pale lemon-colour, slightly pectinated. 

 Thorax thickly clothed with long erect paler hairs ; fore border black. 

 Abdomen ochraceous, cylindrical, very little shorter than the interior 

 border of the hind wings, with six deep black bands ; apical tuft 

 thick, composed of long hairs. Legs black ; femora and tibiae densely 

 clothed with long reddish hairs. Wings slightly hyaline ; veins 

 brown ; a brown streak across the end of the areolet, most distinct in 

 the fore wings ; the latter with an exterior oblique whitish line, which 

 is bordered with pale brown on the outer side and extends from the 

 middle of the interior border to three-fourths of the length of the 

 costa, near which it is dilated. Length of the body 16 lines; of the 

 wings 50 lines. 



It is most allied to D. quadricolor, from which it may be dis- 

 tinguished by the line and the spot on the fore wings.
