We have selected as paratyiies a series of fourteen males and 
twenty females bearing the same data as the type. This serii's, 
as a wlioU', is relatively uniform in size, and in the features of the 
sjieeies. The wing liar shows some variation in intensity and 
solidity, in giuieral its thud nation is solely one of intensification 
or reci'ssion, and its aiaai remains the same and its margins as 
lacking in sharp definition. 
Material of the specie's from Bill Williams Mountain, Flag- 
staff, San I'h’ancisco Mouidains and Dewey is unilorm in charac- 
ter, of similar geiu'i'al jiroportions, wing structures and patte'rn.
