446 PICIDA. 
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 Apaché 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.
