I will now refer to some characters of the Hepialidie wliicU further show that tliey are- 

 colossal Tineoicls, and should be placed very near the base of the order, though still proving, in 

 their boring larval habits and in the reduced maxillary and labial palpi, the entire absence of a 

 haustellum and of mandibles, that the family (at least Hepialus and Stheuopis) has undergone a 

 considerable degree of moditication, compared with the Micropterygida;.

Beginning with the larva, tliat of the Australian Oncopcra inlHcata, when compared with 

 the larva of the colossal Tineoid moth, Maroga ui^ipunctaria, of South Australia, is the same in 

 structure, though less specialized in the colors of the tubercles and in the sculpturing of the 

 head, but it has the same shape of the body, the same arrangement of the one-haired tubercles, 

 though the setie are smaller and shorter, and the same complete circles of crochets on all the- 

 abdominal legs.
