Ilir United States), but in some the female is more reduced than in any 

 other known form of Lepidoptera, and never leaves the cocoon. 



Family 9. TINEID^ffi (somewhat restricted) 



Head usually "with high, rough, bristling vestiture; the vestiture finer 

 and more macro-like in Aeroloplms, and short in a few genera near 

 Amydria which have a strongly bristled palpus. Front often rough 

 and palpus often bristled on side, though but weakly in reduced forms 

 .-iiid not at all in Acrolophus. Maxillary palpus typically five-jointed, 

 folded, sometimes reduced or absent; tongue scaled, or rarely absent; 

 antenna never much longer than wing, but usually more than half as 

 long; often with a pecten, but without an eye-cap; typically with two 

 whorls of scales to a joint, one of them of divergent scales (in Acrolo- 

 phus the antenna is smooth-scaled, with several rows to a segment) ; 

 antenna in our species simple, but pectinate in a few exotic Acrolo- 

 phinas. Fore wing with all veins, or with one vein absent; accessory 

 cell usually present, separated from cell by a long, weak vein; base of 

 media present in lower forms; 2d A frequently forked at base; wing 

 always rather narrow and sometimes lanceolate; hind wing varying 

 from ample (Acrolophus) to linear (fig. 81) ; when broad, with R and 

 M t well separated, but in some genera M x and M 2 stalked ; when nar- 

 row, often with an open cell; with most veins present, but frequently 

 extremely w r eak. No aculere. Hind tibia usually with a mixture of 

 bristles and hair, never smooth-scaled. 



Egg of flat type, oval. Larva with seta? iv and v well separated, 

 otherwise differing in the two subfamilies. Pupa incomplete, with 

 well-marked maxillary palpus; with Adelid prothorax; abdomen with 

 segments 4 to 7 inclusive, free, and 8 in male; but segment 2 fixed; 

 each segment with a single anterior row of spines; tongue shorter 

 than labial palpus. 



The Tineidre appear to furnish the point of origin of each of the 

 higher tineoid superfamilies, and possibly of the macros as well, but 

 the macros seem a little closer to the Yponomeutoids. The two sub- 

 families are not closely related, and could well be treated as families, 

 as they often are.

 posterior tufts; palpus also with deep vestiture, not bristled ( Acrolophinte)
