NEW BEAUTIES FROM NEAR AND FAR. 



BY B. NEUMOEGEN. 



Parnasshis sDiintheus, \ar. nanus. — Prominent entomologists 

 of both hemispheres arrived at the conchision years ago, that the 

 P. intermedius Men. and the P. sniinthcus Doubl.-Hew. of this 

 country are one and the same insect. Typical specimens from 

 western Siberia, which I possess, do not leave the least doubt as to 

 this fact. The Parnassidae of eastern Siberia, Ochotsk, Kamts- 

 chatka, migrated centuries ago across Behring Straits, settling from 

 Alaska down the Rocky Mountain range as far as the borders of 

 New Mexico. 



P. eversmanni, which was first discovered at Kanska and 

 Ochotsk, was obtained in moderate numbers at Nicolajewsk in the 

 last few years, and is the same insect as the one found in Alaska, 

 especially in the Yukon country. Even its female variations, named 

 P. wosnesenskii by Menetries, and P. thor by Hy. Edwards respec- 

 ti\ely, are synonyms, thus substantiating the migration theory. As 

 the northern and southern climate of our " Rockies" vary consider- 

 ably, some variations of P. smi)ithetis have developed, but they re- 

 main true to our country, and deserve proper denomination. 



One of the prettiest variations in its way, which was found by 

 Capt. Geddes, near Fort Calgarry, some years ago, and lately by 

 the botanists of Dr. Dieck, the owner of the renowned Arboretum 

 at Zoeschen, Germany, at Spence's Bridge, both places being in 

 British Columbia, I have named var. nanus. It is the smallest kind 

 of sndntheiis found in America and exceedingly pretty. 



It is of the sedakovii order, but more pronounced. In the % 

 not a vestige of red is left, either on primaries or secondaries. The
