5. Gelechia, Z. 



Head smooth ; ocelli present ; tongue well-developed. An- 

 tennaB f of forewings, in male filiform, simple or pubescent, 

 basal joint moderately elongate, without pecten. Labial palpi 

 moderately long, recurved, second joint thickened with appressed 

 scales, rough beneath, terminal joint as long or nearly as long 

 as second, moderately slender, acute. Maxillary palpi short, 

 appressed to tongue. Posterior tibhe clothed with hairs above. 

 Forewings with vein 1 furcate, 2 from about f of cell, 7 and 8 

 stalked, 7 to costa, 11 from about middle of cell. Hmdwings as 

 broad as forewings or rather broader, trapezoidal, apex pointed 

 or round-pointed, hindmargin shallowly emarginate or hardly 

 perceptibly sinuate, cilia f— 1^ ; veins 3 and 4 from a point, 5 

 from rather near 4, and 7 from a point or approximated 

 towards base. 



The variation in the form of hindwings and length of cilia is 

 used by Heinemann to characterise two groups, Gelechia and 

 Lita, as separate genera ; but these shade so imperceptibly into 

 each other, that I am of opinion tbat the distinction cannot be 

 advantageously maintained : most of the following species are 

 of an intermediate character, and might be ranked almost equally 

 well with either group. As thus limited, the genus is very 

 large, especially predominating in Europe and North America.
