together for a short distance beyond the cell, after which 

 they are again separate 

 (Fig. 270). In some gen- 

 era these two veins do 

 not actually coalesce, but 

 extend very near to- 

 gether for a short dis- 

 tance (Fig. 271). The 

 two types, however, are 

 essentially the same. 



This superfamily in- 

 cludes seven families, 

 which can be separated 

 by the table given below. 

 The Plume -moths are 

 placed last in the series, 

 as we believe that they 

 depart more widely from the primitive type than do any 

 of the other families. 



A. Wings not fissured. 



B. Hind wings without a fringe of hairs on the basal part of vein 

 VII. Care must be taken not to mistake scattered hairs on the 

 anal area of the wing for such a fringe. 

 C. Fore wings with veins III 4 and III 5 separate, vein III 6 arising 



from the discal cell (Fig. 272). p. 230 PYRAUSTID^E. 



CC. Fore wings with veins III 4 and III 5 united at base (Fig. 277). 



p. 232 PYRALIDID.E. 



BB. Hind wings with a fringe of long hairs on the basal part of 

 vein VII. 

 C. Radius of fore wings five-branched. 



D. Maxillary palpi more or less developed, but not triangular 



as in the next family, p. 233 GALLERIID^E. 



DD. Labial palpi long, straight, projecting forward ; maxillary 

 palpi well developed, strongly dilated at tip with scales, ap- 

 pearing triangular when viewed from the side. p. 234. 



CRAMBID/E. 



CC. Radius of fore wings four-branched, veins Ills and III* 

 coalescing to edge of wing (Fig. 281). p. 235 PHYCITID.E.
