remain in all their natural beauty. In the same way the sea- 

 lions are kept as an attractive feature of the harbor. 



If, as is supposed, seviidea is a remnant of the Arctic fauna 

 of the ice age, it is fully as interesting, in its way, as the big 

 trees or Palisades, and is as much entitled to protection as thej'^ 

 are. 



Of course there is a demand for semidea among collectors, 

 but can't the demand be met without exterminating the spe- 

 cies? I think it can. Collectors who work at the White 

 Mountains can do a good deal towards preserving the species 

 by careful collecting. Although I think no true collector 

 would do, some collectors (?) are fond of getting every butter- 

 fly in sight if they can, and it is from such as these that I 

 would have the species protected by law. If certain sections, 

 in which the food plant is abundant, could be set apart as 

 places in which all collecting is illegal, a good deal would be 

 done towards the desired end. 



What does some one else think about protecting our little 

 colony of Arctic exiles ? 



Prosopis Ziziae. 



By John H. Lovell. 



In the March number of Ent. News, Mr. Robertson states 

 that the name Prosopis zizice Robt. is incorrect, and that it 

 should read P. zizia Ckll. He writes, " I have not described 

 any species under the name P. zizice, and have never used that 

 name." But in the Can. Ent., May, 1896, p. 136, after giv- 

 ing the characters of P. affinis Sm., he says, "I think that 

 there is no question but that this is the P. affi7iis of Smith, 

 but the male described by him probably does not belong to it. 

 If, however, this should prove to be distinct from P. afiiiis, 

 the name Prosopis zizicB is proposed for it." Mr. Robertson 

 was, then, the first to write and the first to publish the name 

 Prosopis zizia. As the name is not required it certainly would 

 have been better had it never been proposed. 



In the Entomologist, Prof. Cockerell writes : ' '/*. affinis
