With licr 111.1 xillary tentacle, so womlerrnlly iiiodilied for the purpose, slie collects the jiollen in large pellets and 

 liold.s it nnd<'r the neck and against the front trochanters. In this inanuer she sometimes carries a mass thriel^ the 

 size of her head (fig. a, 1h, mi.). 



Ill Riley's figure of Tri/ciirula (Promiba) maculatn this orsan i.s repre- 



iseiited a.s arising Iroiii the same Joint (pal- 

 pifer) as, the maxillary palpi; it is Jointed 

 and bears stout bristles, and would naturally 

 be regarded as the maxilla itself, but liiley, 

 iu his diagnosis of the family Prodoxida', 

 says: "Maxillary palpi long, elbowed, five- 

 jointed, the basal Joint either protubei-ant 

 (Prodoxus) or modified into a prehensile 

 ieutacle" (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 Kiley is the 

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

 examination to settle this poiut. If this should prove to be the case 

 it would carry the family down among the Lepidoptera luciniata. 



Another striking feature of the imagines of this I'amily is the 

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

 horny, in one piece, and adapted 

 to iiiercing and sawing." (Kiley.) 

 The family evidently is a 

 more primitive one than the 

 Hepialidie, although the lai'va 

 in one genus is entirely apodous 

 and thus much modified. 

 Fdmily Tlneklcc. — This group comprises generalized forms of 

 Tineina. The larvib are sack-bearers, but 

 have five pairs of abdominal legs ; the wings 

 are rather broad and the venation is gener- 

 alized, that of Tinea bisellieUa showing no 

 reduction in the number of veins. The max- 

 illary palpi are five and six-Jointed. The 

 pupa (fig. IG, Tinea tapetzella) has well-devel- 

 oped maxillary palpi {m.v. p.)- the maxillie

palpi (m.r.p.); the abdominal segments 4-7 



are free; there is no true cremaster, though 



a pair of terminal plates. As regards IJlabophanes (fig. 17), Spuler' (p. (127) 



remarks that the ditterences iu veuation between this and Tinea are so 



much greater than usual within the limits of a single family that a mo;e 



isolated position should perhaps be assigned to this genus. 



The succeeding families of geuuineTiueina may provisionally be arranged 

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

 and ending with 2>, the most modified forms.
