Kirby : Both species are allied to A. disco/or, Proc. Acad. Nat. 

 Sci., Phil, 1873, 326. The foregoing discussion seems to warrant the 

 following synonymy : — 



Agabiis disco/or, Harris, Massachusetts, (seemingly unknown). 

 A. phceopterus, Kirby, British America ; lat., 54°. 

 A. Lecontei, Crotch; disco/or,\\LQC.;p/icEOpterus, \\ Mann. California, 

 San Francisco, Vallecitas ; ? Alamosa, on the Rio Grande, at 

 7,600 feet, (differs in being less oval and more parallel, Leconte); 

 Alaska, Peninsula of Kenai, Island of Afnognak. 

 A. obliteratus, Lee; Kansas, Ft. Laramie, Lawrence ; Colorado, 

 Leavenworth Valley at 10-1,1000 feet; Southern Colorado; 

 Northern New Mexico ; Wyoming, Lake Como. 

 A. bicolo7\ Kirby. — A single specimen was taken by the Richardson 

 expedition at lat. 54°. It likewise occurred in Alaska on the peninsula 

 of Kenai. — Mannerheim. While in Europe Dr. Leconte examined $ 

 and % types, giving brief descriptions of each (Proc. Acad , 1. c). This 

 appears to be a good species and, ^^x^Xx phceopterus, should have a place 

 in our catalogues. 



Phceopterus^ Leco/itei, and bicolor seem very close, and their separa- 

 tion by the various descriptions without the presence of examples could 

 not prove very satisfactory. 



CERURA SCOLOPENDRINA, Boisd. 

 I think I have satisfactorily identified this species. I captured a speci- 

 men at Yosemite, California, on June 5th, 1891, that bears out Boisduval's 

 description. The specimen, however, is Centra aquilonaris, Lintn., and 

 these names will have to be considered as referring to the same species. 

 I have also received a specimen from Mr. C. A. Wiley, of Miles City, 

 Montana, so the species probably occurs from the Atlantic to the Pacific. 

 The synonymy will stand as follows : — 



CeRUR.A. SCOLOPENDRINA, Boisd. 



1S69 — Boisduval, I-ep. de la Cal, p. 86. 

 Aquilonaris, Lintn. 



1877 — Lintner, 30th Rept. N. Y. State Mus., p. 197. 



1891— Thaxter, Can. Ent., Vol. XXIIL, p. 34. 



It is unfortunate that the rule of priority will not allow us to retain 

 Prof. Lintner's name for this species, since his characterization of it is so 

 careful and exact as to render its recognition easy, which is not the case 

 with Boisduval's description. Harrison G. Dyar.
