446 PICID^. 



The most northern record of this species is reported by Mr. Ridgway, who says * that 

 Lieut. H. C. Benson, of the U.S. Army, when scouting in the Apache country, found 

 C. imperialis to be common in the Sierra Madre, in Sonora, fifty miles south of the 

 frontier-line in the pine-forests, A head only was brought home, sufficient, however, 

 to render the determination of the species certain. 



Whether C. imperialis crosses the frontier into United States Territory or not has 

 yet to be determined. The probability of its doing so depends upon the continuity of 

 the great pine-forests which clothe the sierras of these districts. The political 

 boundary is quite arbitrary so far as any physical features of the country are 

 concerned.
