Fig. 12.— Head of pupa of 
Tegeticida yuccasella. 
With her maxillary tentacle, so wonderfully modified for the purpose, she collects the pollen in large pellets and 
holds it under the neck and against the front trochanters. In this manner she sometimes carries a -mass tlirico the 
«ize of her head (fig. a, Ih, mi.). 
Ill Eiley’s figure of Tegeticuia (Prouuba) maeulafa this organ is repre- 
sented as arising from the same joint (pal- 
pifer) as thb maxillary palpi 5 it is jointed 
and bears stout bristles, and would naturally 
bo regarded as the maxilla itself, but Eiley, 
in his diagnosis of the family Prodoxida*, 
says: Maxillary palpi long, elbowed, five- 
jointed, the basal joint either protuberant 
(Prodoxus) or modified into a prehensile 
tentacle” (Tegeticuia). It is evident that 
this structure needs further examination 
to establish its real nature or homology. 
Indeed, I am disposed to regard the so-called “maxillary tentacle” 
as the maxilla itself, and perhaps the “maxilla” of Eiley is the 
lacinia or inner lobe of the maxilla, but have had no material for 
examination to settle this point. If this should prove to be the case 
it would cany the famil}' down among the Lepidoiytera laciniata. 
Another striking feature of the imagines of this family is the 
long ovipositor, which is very “ extensile, the terminal joint 
horny, in one iiiece, and adapted 
to piercing and sawing.” (Eiley.) 
The family evidently is a 
more primitive one than the 
Hepialidie, although the larva 
in one genus is entirely apodous 
and thus much modified. 
Family Tineidw. — This group comprises generalized forms of 
Tineina. The larva? are sack-bearers, but 
have five iiairs of abdominal legs; the wings 
are rather broad and the venation is gener- 
alized, that of Tinea biseliiella showing no 
red action in the number of A'eins. The max- 
illary palpi are five and six-jointed. The 
pupa (fig. IG, Tinea iapetzella) has well-devel- 
oped maxillary palpi j).); the maxilla? 
are short, indeed not so long as the labial 
palpi (»u;. p,); the abdominal segments 4-7 
are free; there is no true cremaster, though 
a pair of terminal idates. As regards Elabophanes (fig. 17), Spuler^ (p. G27) 
remarks that the differences in venation . between this and Tinea are so 
much greater than usual within the limits of a single family that a more 
isolated position should perhaps be assigned to this genus. 
The succeeding families of genuine Tineina may i^rovisionally be arranged 
in the following ascending order, beginning with A, the more generalized,

lary palpi in moth. Larva of Adela with numerous dorsal piliferous plates, 
those of Simmthis being similar; those of Xeinatois (fig. 8) being confined to the thoracic segment.
