June, 1903.] Coleman: Coccid.e of the Conifer.1v. 71 



Newly born laiVce were found on the white fir {Abies cotico/or), 

 at Shasta Camp, Aug. 19, and on the red fir {Fseiniotsiiga iaxi/o/ia), 

 in the Stanford arboretum, Dec. 15, 1901. 



At nearly all stations where studied the young we found in all 

 stages of development. It would seem from this that there is no well- 

 defined breeding season and that breeding goes on throughout the 

 year, the abundant season varying with the elevation and climate. 



Distribiitiou. — The first specimens were found by the author, on 

 the red fir (^Pseudotsuga taxifolia), near Saratoga Summit, Sierra 

 Moreno Range, about twenty-five miles south of Stanford University, 

 July 6, 1900. These specimens were sent to the Division of Ento- 

 mology, U. S. Dept. of Agriculture, where Mr. Pergande identified 

 them as a Leucaspis, sp. Since this first date I have found them on 

 the red fir as follows : Mountains West of Napa City, Napa Co. , 

 June 17, 1901 ; Cobb Mt. and hills about it, Lake Co., June 21, 

 1901 ; mts. near Blue Lakes, Lake Co., June 25, 1901 ; from the 

 head of Big River, Mendocino Co., all through the Coast Range to 

 near Mendocino City, thence northward and throughout a forest of 

 this species about thirty miles in width, in the northeast part of Hum- 

 bolt Co., in June, 1901, and near Dunsmuir, Siskiyou Co., August 

 25, 1901. 



I have also found this scale on Abies ic^rainiis, near Casper and 

 Rockport, Mendocino Co. ; on Abies eoneolor near Salmon Forks, 

 Siskiyou Co., and at Shasta Camp, Mt. Shasta ; in Stanford arboretum 

 and on some herbarium specimens of Abies magnijica from La Porte, 

 Pulmas Co., and from "Trail to Sentinel Dome," Yosemite : on the 

 Shasta fir {Abies shasfensis), near the east side of the summit of 

 range, west of Salmon Forks, Siskiyou Co., California. 



Evidently the scale is not confined to Pseiuiotsuga faxifo/ia although 

 it seems to be most abundant on that species.
