1. BACTRA LANCEOLANA (Hnbner) 



(Figs. 44, 342)

Pierce's figures of the genitalia fix the concept of this species to 

 a form with broad, roundly arched incurvation on lower margin of 

 harpe between sacculus and cucullus. In furfurana^ which is very 

 close in genitalia, pattern, and general habitus, the lower margin of 

 harpe is angulate and there is no incurvate or definable neck area 

 (comp. figs. 44, 45). European and American workers have fre- 

 quently confused the two species, identifying suffused and Aveakly 

 marked furfurana as lanceolana. The latter occurs here, but is quite 

 rare. All the American specimens I have seen under the name are 

 referable elsewhere, some few to Tnaioi'ina, but the greater number to 

 furfurana or verutana (var. alhipuncta) . The majority of the 

 European specimens in our collections under lanceolana (and so 

 labeled by European workers) are also furfurana. 



Male genitalia figured from specimens in National Collection from 

 British Columbia (E. H. Blackmore, "60, F-13-VIII-20"). 



This is the only authentic American specimen I have seen.

A common species throughout the United States. The characters 

 given in our key will distinguish the more strongly marked speci- 

 mens (that is, those with complete basal patch, and median bar 

 extending to costa) ; but the species is quite variable and specimens 

 marked like typical lanceolana are not uncommon. In fact these are
