1. Tineoids nr Stctnipteriiijiii. 



These iire Tiiieoid forms with iiiaiiy vestiyes of areliaic features, iistiiilly with narrow wings, 

 of (lull hues or with luetallie. bars, or with hi.niily specialized scales, and spot"^, and the venation 

 generalized in tlie earlier forms. The maxilhe are sometimes aborted (wholly so in Ilepialidai); 

 l)ali)i either well develoi)ed, more or less reduced, or wanting; ni;iudil)les rarely 0(;(uirring as 

 minute vestiges; the thorax iieuroptt'roid; in the more primitive forms, becoming shorter, and the 

 segments fused together in the later or more sjjecialized groups. 



The pnpa,' are incomplete; the more prinutive forms with the eye collar; labial jialpi visible; 

 paraclypeal pieces distinct; abdomen (d'ten in the most piimitive forms with no creniaster. 



LarviB with one-haired tubercles, the four dorsal ones arranged in a trapezoid on abdominal 

 segments 1-8; usually a prothoracic dorsal plate; the abdominal legs sometimes wanting in certain 

 uduing forms and Cochliopodid;e; larv;e often case-bearers or borers; crochets on the abdominal

legs in the primitive types arranged in two or more complete circles; in the lowest forms a well- 

 marked spinneret. 



From the generalized types many offshoots or lines of descent arose whose position is difficult 

 to assign until we know more about the pupa^, as well as the venation, so that the following 

 grouping is entirely provisional; the more generalized forms are evidently archaic and very 

 primitive, and the members of the groups may be briefly called for convenience Tineoids, from 

 their general resemblance to the Tineina. 



Remarks oh the Tineina. — It must now be very obvious that we need to reexamine and revise 

 the Tineina, and espec'ially their pupre and imagines, particularly those of the more generalized 

 forms, such as the Tineid;e (Tinea and lilabophanes) and the Tahei)ori(he, comprising all those 

 ancestral forms with broad wings and generalized venation, which may have given rise to the 

 neolepidopterous families. 



Then careful studies should be made on the Adelida^, Choreutid;?, arid Nepticulidse, and other 

 families and genera in which the mandibles have pei'sisted (though in a vestigial condition),.
