Other references

[Xylorycta leucophanes] Nearest to orectis, Meyrick. (Lower, 1892).

[Xylorycta homoleuca] Between orectis, Meyr., and leucophanes, Lower. From the former it differs in absence of orange costal edge, &c.; and from the latter by the absence of blackish costal edge, color of hind wings, and shape of forewings. (Lower, 1894).

[Xylorycta homoleuca] This is certainly very near X. orectis, Meyr., differing only in the total absence of ochreous tinge on head, thorax, and costal margins and the fuscous colouration of legs. (Turner, 1894).

[Xylorycta amphileuca] Nearest orectis, Meyr., but differs from that and the allied species by the absence of orange on head and fuscous hind-wings. (Lower, 1902).
