Revision of the hitherto known species of the genus CHIONOBAS in North 



America. 



BY SAMUEL II. SCUDDER. 



I Co7nmunicated June 12th, 1865.) 

 Having long- been de^iirous of comparing the species of Clu'onohas 

 described by Say under the name of Hijipan-hta srmidca. of which I 

 have seen a large- number of specimens, with the subarctic species of 

 the same genus indicated or described by authors as living in the cokler 

 regions of this continent, no specimens of which have hitherto found 

 their way into the museums of this country, it was with great satisfac- 

 tion that I was given the opportunity of examining an interesting col- 

 lection of this genus made by my friend and fellow student Dr. A. S. 

 Packard. Jr.. on the coast of Labrador, near the northern extremity 

 of the Straits of l]eilo Isle, and as far north as the mission station of 

 Hopedale ; it comprised all but one of the species hitherto described or 

 figured, or in any way indicated as coming from that region — that ex- 

 ception was made good to me through the favor of 3Ir. W. H. Edwards, 

 to whom I have been so frequently indebted for the gift and loan of 

 specimens desired by me in my studies, and for many useful notes upon 

 them; frf)m him also I have received specimens from Labrador ticketed 

 by Moschler, the latest reviser of the Pjuropean species, which have 

 been of great service to me, and also a specimen of the only species yet 

 described or figured from the western portion of our continent. With- 

 out doubt other .species will be added so soon as that region is explored, 

 which will not be long hence, we may be sure. Already another spe- 

 cies is indicated from that region, obtained ly Mr. Lorquin. In the 

 meantime it has seemed to me a useful undertaking to attempt to .scru- 

 tinize the relations of the species already known on this continent, and 

 to understand what this and that author have meant by Oeno, A/so.
