In the Diplodomidse (winged females, triangular cases) the female 

 antenna appear to have complete scaling, with no area reserved to 

 hairs, and in two complete circles. In the male the lower surface 

 is free from scales and covered with hairs, which are, however, some- 

 what aggregated in a thickened base of each segment. 



In the Talajporidse (araneiform females, triangular cases). The 

 female antenna; are, as in all the families that are more specialised, 

 degenerating, and have practically lost all hairs and scales, not as a 

 specialisation, but as a step towards the disappearance of the 

 antenna altogether. 



In the male the scales are definitely confined to the dorsum, the 

 hairs to the ventral aspect of the antenna;. The scales appear to be 

 always in two rows, easily distinguished, but the hairs, which are 

 long, as in typical Psychids, and abundant, are sometimes uniformly 

 distributed, Solenobia tnconspicieelia, vianuii, etc., group, alpestrelia, 

 etc. ; and in others are aggregated basally, or into two groups, 

 Talcp-poria {pseudobombycelld) and Bankesia {conspurcatdla). 



Dissoctena granigerella belongs to a group separate from any of 

 these, but not very far separate from Melasina. It is essentially a 

 Melasina with apterous female. Though apterous, the female has made 

 none of the progress downwards of the Talaeporiad^e ; it has acquired 

 the long ovipositor required for placing the eggs in the larva case, 

 but it retains a very complete hair clothing of the whole surface, 

 and the antennse are completely scaled in two rows of scales to a 

 segment. The antennal characters, therefore, are those of Melasina^ 

 and appear nowhere else in the whole superfamily. The male antenna 

 is grandly pectinated with pectinations dorsally scaled. 



In the Luffiadae (Z. lapidella and B. sepiuni) with pupal and other 

 characters intermediate between Taljeporiadae and Fumeida;, the 

 antennae have four rows of scales across the dorsal aspect of each 

 segment, and pectinations which, with the ventral aspects of the 

 segments, are clothed with sense-hairs on all aspects. 



In the Fumeidae there are two very distinct sections, both follow 

 the Luffiadae in having four transverse rows of scales to a segment, 

 but already the aligment is beginning to vary and become obscure. 

 In the Proutiid section {betulina, etc.) the hairs affect all aspects of 

 the pectinations • in the Fumeid {sensu strtcio), the dorsal aspects 

 of the pectinations are scaled to the tips. 



The two higher groups of Psychids follow the Proutiids and 

 Fumeids respectively in antennal structure. 



The Epichnopterygids {Epichnopieiyx \pi//ia, sapho, etc.), Bijugis 

 \bo)nhycella^ etc.]) have antennal pectinations, with sense-hairs on all 

 surfaces and without scales. 



The Psychids (restricted) have the antennal sense-hairs confined 

 to the inner aspect of the segments and pectinations. 



They divide into two very definite groups, viz. those that retain 

 the dorsal scaling of the pectinations (Psychini) and those that lose 

 it (Acanthopsychini) ; the latter may at once be known from the
