NORTH AMERICAN LASPEYRESIINAE AND OLETHREUTINAE 27 



Derived from Laspeyresia. Is well represented in Europe and 

 North America. On the ocelloid patch it divides into what appear 

 to be two natural groups. I do not think however that these deserve 

 generic rank, since there are no characters other than the ocelloid 

 patch on which to separate them. 



KEY TO THE SPECIES GKAPHOLITHA 



1. Ocelloid patch of foi-e wing a pair of vertical metallic bars, well separated 



and inclosing one or more black dots or longitudinal streaks 2. 



Ocelloid patch a single vertical bar, or two closely appressed vertical 

 metallic bars scarcely separated by a vertical line of darker scaling 13. 



2. Fore wing with one or more distinct white geminate marks on mid dor- 



sum . 3. 



Fore wing with pale dorsal markings obscure or absent 6. 



3. Fore wing with a faint, scattered dusting of white scales at base, on disk, 



and along termen (10) imitativa. 



Fore wing without such white dusting 4. 



4. Ocelloid patch containing six unbroken longitudinal black streaks; white 



dorsal geminations broad (8) fana. 



Black longitudinal markings of ocelloid patch irregular, broken, and less 

 than six ; white dorsal geminations narrow 5. 



5. Hind wing distinctly paler than ground color of fore wing; post median 



area of fore wing darker than basal area .- (11) lunatana. 



Hind wing dark, nearly concolorous with ground color of fore wing; post 

 median area of fore wing no darker than basal area. 



(9) conversana (part). 



6. Hind wings hyaline white toward base ; broadly margined with dark 



fuscous at apex (12) eclipsana. 



Hind wings sometimes pale toward base but never hyaline white 7. 



7. Fore wing with white dusting on fore wing forming an obscure, angulate 



pale median fascia (7) vitrana. 



Fore wing without such a pale median fascia 8. 



8. Fore wing longitudinally streaked on disk and well dusted toward apex 



with rusty ocherous scales (4) prunivora. 



Fore wing without such ocherous scaling 9. 



9. Fore wing with six or more distinct white geminations on costa 10. 



Fore wing with costal geminations obsolete or distinguishable only as very 



faint, minute streaks 11. 



10. Costal geminations evenly spaced (5) angleseana. 



Apical pair of costal geminations well separated from the preceding four. 



(6) caeruleana. 

 (9) conversana (part). 



11. Fore wing fully half as broad as long; costa appreciable arched toward 



apex (1) molesta. 



Fore wing somewhat less than half as broad as long ; costa straight toward 

 apex 12. 



12. Male with heavy black scaling on hind wing (3) packardi. 



Male without sex scaling on hind wing (2) lihertina. 



13. Four geminate white streaks on mid dorsum of fore wing 14. 



Two geminate white streaks on mid dorsum of fore wing 15. 



14. Entire palpus white (17) tristrigana. 



Palpus strongly dusted with fuscous toward apex (15) lana (part).
