646 The American Naturalist. - [July, 
These are Tineoid forms with many vestiges of archaic fea- 
tures, usually with narrow wings, of dull hues or with metallic 
bars, or with highly specialized shapes of scales and spots, and 
the venation generalized in the earlier forms. The maxille 
are sometimes aborted (wholly so in Hepialide); maxillary 
palpi either well-developed, more or less reduced, or wanting ; 
mandibles rarely occurring as minute vestiges; the thorax 
neuropteroid in the more primitive forms becoming shorter and 
the segments fused together in the later or more specialized 
groups. 
The pup. are incomplete; the more primitive forms with 
the eye-collar and labial palpi visible; paraclypeal pieces dis- 
tinct ; abdomen often with no cremaster in the most primitive 
forms. 
Larve with one-haired tubercles, the four dorsal ones ar- 
ranged in a trapezoid on abdominal segments 1-8; usually a 
prothoracic dorsal plate; the abdominal legs sometimes want- 
ing in certain mining forms (and Cochliopodide) ; larve 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. 
Remarks on the Tineina.—It must now be very obvious that 
we need to re-examine and revise the Tineina, and especially 
their pup and imagines, particularly those of the more gen- 
eralized forms, such as the Tineide (Tinea and Blabophanes), 
and the Taleporide, comprising all those ancestral forms with 
broad wings and a generalized venation which may have given 
rise to the neolepidopterous families. 
Then careful studies should be made on the Adelidæ, Cho- 
reutidee and Nepticulide, and other families and genera in 
which the mandibles have persisted (though in a vestigial 
condition), and also those with functional or vestigial maxil- 
lary palpi, such as Tineidw, Gracilariide, Elachistide, etc. 
It is evident that the classification of the Tineina will have 
to be entirely recast; instead of placing the Tineide, with 
their broad wings and generalized venation at the head of the 
Tineina as done in our catalogues and general works, they 
should go to the base of the series, not far from the Microptery-
