Type: 9, "on fir logs," Robson, B. C, Sept. 25, 1938, H. R. Fox- 

 lee (Washington, USNM 63691). 



Para types (639) : From Alberta (Banff) ; British Columbia (Kaslo, 

 Robson, Sugar Lake, and Trinity Valley) ; California (Fallen Leaf and 

 Placerville) ; Colorado (North Cheyenne Canyon); Idaho (Burke, 

 "Krassel R. S.," Potlatch, and Wallace); Maine (Bar Harbor); 

 Montana (Flathead Indian Reservation, Lake Macdonald in Glacier 

 National Park, and Thompson Falls) ; Nova Scotia (Kentville) ; 

 Ontario (Fairy Lake) ; Oregon (Detroit and Government Camp on 

 Mount Hood) ; Quebec (Laniel) ; and Washington (Kent and Metaline 

 Falls). 



Collecting dates are from spring to late in the fall but about 60 

 percent of the specimens were taken in September and October. 

 Unusually early and late seasonal records are: April 24 at Robson, 

 B. C; May 15 in Trinity Valley, B. C; June 1 at Kentville, N. S.; 

 October 6 and 9 at Potlatch, Idaho; October 1, 6, 16, 21, 22, and 25 at 

 Robson, B. C; and October 18 at Wallace, Idaho. 



Thirteen of the specimens are labeled "on fir logs," which in this 

 case probably means Pseudotsuga taxifolia. One specimen is labled 

 "on Abies concolor," one labled "Pinus ponderosa," one labeled "on 

 Pinus montana," one labeled "Pinus scopulorum," one labeled "Pseudo- 

 tsuga taxifolia," and there are more exact biological records as follows:

 drumm,ondi and Semanotus ligneus, Kent, Wash., Burke. 9, ovi- 

 positing in log of Pseudotsuga taxifolia infested with Melanophila 

 drummondi, Flathead Indian Reservation, Wash., Sept. 10 to 14,
