Fig. 12 Head of pupa of 



Ti'ffeticida ynccasella. 



"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 thrice the 

 size of her head (fig. a, 7b, mt.). 



Ill Eiley's figure of Tcf/eticula (Pronuba) maculata this organ i.s repre- 

 sented as arisiug from tlie same Joint (pal- 

 pifer) as tlie maxillary palpi; it i.s jointed 

 and bears stout bri.stles, and would naturally 

 be regarded as the maxilla itself, but Riley, 

 in Ids diagnosis of the family Prodoxidie, 

 says: "Maxillary palpi long, elbowed, five- 

 jointed, the basal joint either protuberant 

 (Prodoxus) or modified into a prehensile 

 tentacle'' (Tegeticula). 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 Riley is the 

 lacinia or inner lobe of the maxilla, but have had no material for 

 examination to settle tliis point. If this should prove to be the case 

 it would carry the family down among the Lep'ulopiera laciniata. 



Another striking feature of the imagines of this family is the 

 long ovipositor, which is very " extensile, the terminal joint 

 horny, in one piece, and adapted 

 to piercing and sawing." (Riley.) 

 The family evidently is a 

 more primitive one than the 

 HepialidiC, although the larva 

 in one genus is entirely apodous 

 and thus much modified. 

 Fumihj Tineidce. — This group comprises generalized forms of 

 Tineina. The larvic are sack-bearers, but 

 have five pairs of abdominal legs ; the wings 

 are rather broad and the venation is gener- 

 alized, that of Tinea hiseUidla showing no 

 reduction in the number of veins. The max- 

 illary palpi are five and six-jointed. The 

 pupa (fig. 10, Tinea tapeizeUa) has well-devel- 

 oped maxillary jjalpi {mx. p.); the maxillre 

 are short, indeed not so long as the labial 

 palpi (mx.2)-); the abdominal segments 4-7 

 are free; there is no true cremaster, though 



a pair of terminal plates. As regards Blabophanes (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 provisionally be arranged 

 in the following ascending order, beginning with A. the more generalized, 

 and ending with B, the most modified forms.
