RESTRICTION OF THE GENUS GELECHIA— BUSCK 577 



of species Pierce and Metcalfe ^' suggest that a new genus is required, 

 but the transition from the typical form of signum with the t»vo 

 transverse ridges and surrounding scobinate plate, which by them- 

 selves form a rectangle, seems natural, and I include all these species 

 (genus 20 of Pierce and Metcalfe) in Bryotropha.

9. FRUMENTA, new genus 

 Plate 60, Figure 14 ; Plate 68, Figueb 49 



Second joint of labial palpus with well developed, slightly fur- 

 rowed brush on under side ; terminal joint shorter than second, thick- 

 ened with scales in front, apex acute. 



Fore wing with vein 2 well before angle of cell; 3, 4, and 5 equi- 

 distant at base, nearly parallel from end of cell; vein 6 approximate 

 to stalk of 7 and 8. Hind wing broader than fore wing, termen but 

 slightly sinuate, apex not produced ; veins 3 and 4 short-stalked, vein 

 5 cubital, but distant from and nearly parallel to 4 ; 6 and 7 separate. 



Male genitalia Avith large hood-shaped uncus; gnathos a large flat- 

 tened, spoon-shaped liook; harpes simple, robust, with rounded apex 

 bent downward. Vinculum large with tAvo short, stout, hairy proc- 

 esses posteriorly ^° and with a long slender process anteriorly. 

 Aedeagus slender, nearly straight, with bulbous base. 



Female genitalia with ductus bursae moderately long, narrow, 

 slightly twisted; bursa long elliptical; sigmim a single, straight, 

 robust spine with blunt apex. 



In the character of the palpi, scaling, and aedeagus this genus is 

 similar to Gnorimoschenia and is probably correlated with or derived 

 from it. 



Genotype, Gelechia nundinelU Zeller." This is the only species at 

 present included. 



" Genitalia of the tineid families of Lepidoptera of the British Islands, 1035. 



15 This part of the genitalia, including the bases of the harpes. is stronirly sclerotized 

 and fused, and it is debatable whether the two short posterior processes actually belouK to 

 the vinculum or should be considered the lower branches ol' the haipes ; but coinparisoD 

 with other forms in which both branches of the harpes are clearly developed, and in which 

 similar processes are found on the vinculum at the same time, Indicates that the present 

 conception is correct.
