HYPPA INDISTINCTA Smith. 



Three specimens, July 19, 21 (Bear Lake Mountain). 1 am in some 

 doubt of the determination. Smith described liuUdincta from one 

 male from Mount Hood, Oregon, which ai)peared to him to be and 

 probably was aberrant in markings. He has identitied as this species 

 a female in the National Museum from Easton, Washington (Koebele). 

 The length of the pectinations of the male antemia* was not stated. 

 Later I identitied some specimens from Alaska (llarriman expedition) 

 with the European rectilinea Esper. Recently Smith described l>r>i,t- 

 neicrlsta from Calgary, Alberta, without any refereiu-e to or com- 

 parison with reetllhiea or hidistincta, but with the statement that the 

 male antennal pectinations are longer than in the t^astern .ri/lliionhs. 

 In all that has l)een pu])lished there is nothing tangible to diU'erentiate 

 indldlncta Smith, nctllinai Pyar (not Esper), and hr>in»r!r,'!sfa
