BRITISH LEPIDOPTERA. 



Subfam. : luffiinae. 

 Tribe : luffiidi. 



With regard to the tribe in which Luffia and Bacotia are placed, it 

 may be pointed out that it offers in its genera considerable differences 

 from the Taleporiids and Fumeids, with which, in different ways, it 

 appears to be most closely allied. The general characters already dealt 

 with, such as the difference of the larva3, pupse and imagines, may be 

 supplemented by differences in the genera themselves. Thus we find 

 the following difference of neuration : 



Luffia. — Forewing : lc present. Hindwing : transverse nervure 5-7 straight. 



Bacotia. — Forewing : lc absent, Hindwing : transverse nervure 5-7 angled. 



Not only do the $ antennae of the Lufnids differ markedly from 

 those of the allied families, but they differ much inter se, agreeing with 

 those of Whittleia reticella, in having the 1st joint of flagellum (3rd of 

 antenna) without pectinations and in the pectinations being free from 

 scales. The antennas of the two genera, however, differ considerably 

 inter se, as may be seen from the following : 



1. Luffia (lajnddla). — 1st segment ^short, thick (but smaller than in F. casta), 

 and not globular ; 2nd segment short, thick, square ; 4th segment with short 

 pectinations (one-half the length of the segment) ; 5th-12th segments, pectinations 

 rather longer than segments ; 18th-19th segments (final two) without pectinations. 

 Scales on dorsum of segments long, one from base of segment nearly as long as 

 segment, one from apex extends halfway along the next segment. Pectinations 

 apparently scaleless, hairs pale (more numerous and shorter than in F. casta), about 

 one-fourth length^of (sayjhe"9th)~segment. 



2. Bacotia (sepium). — 1st segment large, rounded, wingshaped ; 2nd segment 

 large, square ; 3rd segment belongs to flagellum, short, square, without pectina- 

 tions ; 4th segment short, square, without pectinations ; longest segments about 

 10th-14th ; pectinations longer than segments, broad and flat at about two-thirds 

 of their length ; terminal joints shorter, last two very short, but wide and spathu- 

 late, the last one without pectinations. Scales on dorsum of segments in two rows, 

 two-thirds length of segments. Pectinations scaleless.
