I will now refer to some cliaracters of the Hei)ialidm which further show that they are 
colossal Tiueoids, and should be placed very near the base of the order, though still in’oving, in 
their boring larval habits and in the rediiced maxillary and labial palpi, the entire absence of a 
haustellum and of mandibles, that the family (at least Hepialus and Sthenopis) has undergone a 
considerable degree of modification, compared with the Micropterygidm.

Beginning -with tlie larva, that of the Australian O^icopera intricaia, when compared with 
the larva of the colossal Tineoid moth, Maroga nnipunctcirUi, 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 setm are smaller and shorter, and the same complete circles 'of crochets ou all the^ 
abdominal legs.
