6. Genus CHIONODES Hubner 

 Plate 59, Figubes 6-9 ; Plate C6, Figubes 40-43 



Chionodes Hubner, Verzeichniss bekannter Schmetteiiinge, p. 420, 1816. (Geno- 

 type, Chionodcs luctiflcclla Hiibner, synonym of Tin<:a lugtihreUa Fabricius.) 



Second joint of labial palpus with slightly furrowed brush be- 

 neath ; terminal joint smooth, pointed. 



Fore wings with veins 2 to 6 equidistant. Hind wings with veins 

 3 and 4 connate or short-stalked ; 6 and 7 closely approximate, con- 

 nate or stalked. 



Male genitalia with uncus large, hood-shaped, sometimes divided 

 at apex; gnathos a strong curved hook; harpes very variable, even 

 within the species, and often asymmetrical, upper arm normally long, 

 slender, somewhat enlarged and commonly bifurcate at tip, but some- 

 times, within the same species, reduced, asymmetrical, with the right 

 harpe much shorter than the left, and sometimes (the genotype) 

 rudimentary; lower arms short, stumpy, spiny at apices; acdeagus 

 elongate, with long slender stalk below entrance hole for penis, apex 

 with strongly modified lateral projections. Eighth segment de- 

 veloped into large enveloping upper and lower sheaths. 



Female genitalia with upper part of walls of ductus granulated, 

 bursa large, with upper part of wall spined; signum oval, dentate 

 with stronger teeth along its edges. 



In spite of the diversity of forms and the individual variations in 

 the genitalia, they conform to a general, easily perceived i)attern, 

 and the genus, as restricted, constitutes a natural group, which should 

 not be further subdivided.
