AET. 11 COMMOKT OLD WORLD SWALLOWTAIL BUTTERFLY — CLARK 7 



lower border of the orange anal spot is thicker, encroaching more 

 on the spot itself. 



On the wider side the submarginal yellow spots of the fore wings 

 are rather small, well rounded, and entirely separated from each 

 other by black veins, the row of spots occupying less than half the 

 width of the black border itself, whereas in P. m. aliaska this row 

 of spots is represented by a broad yellow band, quite continuous or 

 with indicated interruptions at the veins, which occupies more than 

 half the width of the black border. 



On the hind wings the inner margin of the dark border is more 

 regularly curved, the black lines forming this margin being only 

 slightly discontinuous between veins K, and R3 and R3 and Mi, 

 whereas in P. m. aliaska the black lines in these interspaces are very 

 widely separated from the corresponding lines above; the dark 

 border is less heavilv washed with blue and olive scales: the sub- 

 marginal lunules are smaller; the black border of the orange anal 

 ocellus is very narrow laterally, sometimes even almost completely 

 interrupted, but posteriorly is broadened into a conspicuous black 

 oval spot deeply excavating the posterior portion of the ocellus; 

 and there is no orange scaling between the cell and the dark border 

 between veins R2 and R3, and R3 and Mi, or above the orange anal 

 spot. The black border of the anal ocellus above is narrow, as in 

 P. m. macliaon^ and beneath it is a narrow crescent of blue scales. 



The dark markings above are dark brown, not intense black as in 

 P. m. aliaska^ giving the insect a rather washed-out appearance. 



Type specimen. — U.S.N.M. No. 34478, female, from Kettle Rapids,. 

 Nelson River, Manitoba, on the Hudson Bay Railway, July 8, 1914 

 (William Barnes collection).

 and one male from Hymers, Ontario (on the northwestern shore of

 boundary), July 8, 1915 (Barnes collection). 



Other records. — Rupert House, on the southeastern shore of James 

 Bay (Edwards, 1868, 1882, 1883; Scudder, 1869; Holland, 1931); 

 Labrador (Weidemeyer, 1863 ; possibly based on the specimens from 

 Rupert House) ; peninsula of Labrador, on the eastern shore of 

 Hudson Bay (Holland, 1931 ; possibly one of the specimens recorded 

 by Edwards from Rupert House) ; Nagagami River, north of Lake 

 Superior (Wilson, 1904). 



Range. — From Kettle Rapids, near Port Nelson, at the mouth of 

 the Nelson River on the western shore of Hudson Bay, to Rupert 

 House at the southeastern extremity of James Bay, and Hymers, 

 Ontario, on the western shore of Lake Superior a few miles north of 

 the Minnesota boundary. This form inhabits low and largely 

 forested country.
