Cremastor viewed from ai)ovo very long and slender, tapering a little, twice as long as Its medium brcadtli, rather broadly and deeply channeled as far as the terminal ridge; viewed laterally it is cipial, a little enlarged at the very tip, slightly curved; the apical Held of hool^lets nearly circular, a little i)rodnced at the anterior outer surface. Anal booklets not very long, moderately slender, tlii l)asal half straight and equal, tlie apical lialf but not greatly, curved Into something like a semicircle, tlic apex bent a little more and directed toward tlie liase, tlie tip bluntly pointed. The buttei-flics of this genus are siiread over iieurly the whole north tem- perate zone, hut tlieir metropolis is im(piestionai)ly North Ameriea.* Only tlu'ee species distinct from American forms are known to occur in the Old World and these are all representatives of North American species ; one of them is confined to southern Europe and western Asia; a second occurs fiuther south in Chimi; wiiilc the third extends from ocean to ocean. One more species which has been identified with our progne, but which will more likely [ to l)e its representative zejihyrus Edw., has been found in the extreme north east of Siberia.
