GENUS PAMPHILA 239 



been known for half a century, it has never been figured either in 

 Europe or America up to this day. The type locahty is given in 

 the books as Napa County, Cal., but I place no great dependence 

 upon the localities noted in those early days, for usually the name 

 "California" was sufficient to cover a multitude of places. For 

 myself I have never taken a Ruricola in Napa County, but have 

 found them further at the north, most of them bear the data 

 Sisson.

 This species, and the next, Viridis, are the largest of the West- 

 ern Pamphilas, and they are very robust and vigorous, fond of 

 feeding on flowers, and that is the time to take them, for their 

 flight is very rapid, so that you do not see them until they halt 

 to feed on the blossoms of some favorite plant. There are some 

 differences in the markings on the upper side of the female, but 

 the most prominent species-mark is on the underside of hind wing, 

 the inner third of which is buffy, blank. The square white spots 

 are more or less connected together.

 This is the largest of all the Western Pamphilas ; it is a moun- 

 tain species, and not seen on the lowlands at any point. Viridis 

 is a shade darker on upper side than Juba, and the black discal 

 dash in middle of fore wing is not broken, as it is in Juba ; and on 

 underside of hind wing the color is greenish ; it was on account of 

 this greenish color that Viridis was separated from Juba. But 

 it seems to me that the broken dash on fore wing is a more im- 

 portant feature, for sometimes the green color is scarcely to be 

 depended upon.
