I will now refer to some cliaracters of the llepialid:e which further show that they are 

 colossial Tineoids, and sliould be ph\ced very near the base of the order, though .still proving, iu 

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

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

 considerable degree of modification, compared with the Micropterygida;.

Beginning with the larva, that of the Australian Oncopcrii iii1ric<it<t, when compared with 

 the larva of the colossal Tiueoid moth, Maro;/a nnipunctaria, of South Austi-alia, is the same iu 

 structure, though less specialized iu 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 .set;e are smaller and shorter, and the same complete circles of crochets on all the 

 abdominal legs.
