2. GELECHIA Hiibner 



(Cirrha Chambers; (Eseis Chambers; Pseudochelaria Walsingham ; 

 Teleia Heinemann; Lit a Treitschke) 



Palpi with second joint rough-scaled; most often with a divided brush or tuft 

 which is sometimes very large; third smooth, more slender than in Gnorimoschema. 

 Fore wing (fig. 155) normal, oblong or pointed, variable in breadth; M 3 and Cuj 

 sometimes stalked in G. bosquella; hind wing never much narrower and usually 

 rather broader than fore wing, typically trapezoidal, strongly sinuate below apex 

 in subgenus Lita; R and M t sometimes stalked, M 3 and CUj connate or short- 

 stalked; M, approximate to M 3 . 



(Eseis Chamhers includes the species with very heavy palpal tuft; Teleia those 

 without ocelli, and otherwise normal. This is a somewhat heterogeneous genus, 

 which should be subdivided. It includes forms transitional to several other 

 genera, notably Anacampsis, Gnorimoschema (or rather, the primitive aberrant 

 Gnorimoschemas which are themselves transitional to Phthorimoea) Telphusa, and 

 Duvita.

 5. A fascia also at two-thirds way out. 



6. A triangular white spot at middle of costa 9. viduella. 



6. No spot at middle of costa 8. lugubrella. 



5. No fascia two-thirds way out 2. coloradensis. 



4. No such streak.

1. Ground color not black or blackish with pale markings. 

 2. A contrasting brown-black bar or patch at basal angle. 



3. An oblique light bar a third way out; patch larger 30. walsinghami. 



3. No< such bar; patch smaller 31. pennsylvanica. 



2. No black patch at basal angle. 



3. A black or contrastingly dark oblique bar running to costa near base; 



the ground before it pale fuscous, luteous, or cream white. 



4. Bar diffuse on outer side ; no decided outer fascia .... 29 mediofuscella. 



4. Bar sharply denned on outer side; a similar black postmedial fascia. 



5. Outer margin heavily edged with powdery black; the orbicular a 



black point, well separated from the outer fascia . . 28. pseudofondella. 



5. Outer margin without definite black border; orbicular large and fused 



with outer fascia, or at least with reniform 27. fondella.
