the granules becoming uniseriate midway on disk, first interspace 
much narrower than others; declivity with first interspace narrow, 
convex, with small, rather sparse serrations; second interspace wider 
than first, flat, closely, finely punctured, without serrations; third 
interspace elevated and armed with a row of dark-colored, pointed 
serrations or granules; entire declivity clothed with moderately 
abundant, flat, scalelike hairs. 
Type locality Chiricahua National Monument, Ariz. 
Additional localities —Oak Creek Canyon, Santa Catalina Moun- 
tains, Gila Valley, Ariz.; and Cuchuta, Sonora, Mexico. 
Host.—Cupressus arizonica Greene. 
Additional hosts —Cupressus glabra Sudworth, Juniperus pachy- 
phloea Torrey. 
Type material.—Holotype, allotype, and 21 paratypes, U.S.N.M. 
No. 55407. 
Remarks.—The holotype, allotype, and four paratypes were taken 
from Cupressus arizonica at Chiricahua, Ariz., by D. DeLeon; five 
paratypes from Cupressus in Oak Creek Canyon by DeLeon; one 
paratype from Juniperus pachyphloca Torr., Santa Catalina Moun- 
tains, by M. Chrisman; six paratypes from C. arizonica, Safford, 
Ariz., by Rex King; and two paratypes from cypress, Gila Valley, 
Ariz., by H. B. Wales. 
The two species Phloeosinus cristatus (LeConte) and P. chiricahua, 
new species, are rather closely related, and their distribution over- 
laps to a certain extent in Arizona. P. chiricahua seems to be more 
numerous in extreme southern Arizona, and the writer has seen no 
specimens of true cristatus from the Chiricahua and Oak Creek 
Canyon areas, while in the Gila Valley cristatws is much more 
abundant than chiricahua; and the two species may occasionally be 
found in the same material.
