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. 



Fig. 271. — Wings of Tlascala reducttlla. 



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 III4 and III 5 separate, vein Ills arising 



from the discal cell (Fig. 272). p. 230 Pyraustid;e. 



CC. Fore wings with veins III4 and Ilia united at base (Fig. 277). 



p. 232 PyRALIDIDjE. 



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

 ve : n 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 PHYCiTlDiE.
