pepsinae: tribe macromerini 163 



infuscate, especially in the female. See the keys for a more exact 

 comparison. Specimens from New Mexico, Arizona, and northern 

 Mexico tend to be intermediate between this and the typical sub- 

 species. 



Specimens (43 cf, 1339): From British Columbia (Kaslo, Midday 

 Valley at Alerritt, Salmon Arm, Steelhead, Vernon, and Victoria); 

 California (Antioch, Berkeley, Brentwood, Carmel, Davis, El Dorado 

 County, Fairfax, Forest Home in San Bernadino County, Lafayette 

 in Contra Costa County, Leavitt Meadows in Mono County, Mar- 

 tinez, Menlo Park, Mill Valley, Mokelumne HiU, Morgan Hill, 

 Murphys, Niles Canyon in Alameda County, Oaldand, Patterson, 

 Quincy, San Francisco, Santa Anna, Santa Clara, Saticoy, southern 

 Sonoma County, Tomales Bay, Tracy, Ventura, Westley, and Weston 

 in San Joaquin County); Montana (Lake Roman in Lake County); 

 Nevada (Reno) ; New Mexico (Beulah and Cloudcroft) ; Oregon 

 (Baker, Brookings, Colestin, CorvaUis, Eugene, Grave Creek in 

 Josephine County, Hillsboro, Hood River, Lake of the Woods, and 

 Siskiyou Pass in Jackson County); and Washington (Pialschie and 

 Wawawai) . 



Most dates of capture are from May to early in October. Unusu- 

 ally early and late dates are: Mar. 27 at Berkeley, Calif.; Apr. 23 at 

 Corvallis, Oreg. ; Apr. 24 at Berkeley, Calif. ; Oct. 9 at Corvallis, Oreg. ; 

 Oct. 10 at Whittier, Cahf.; Oct. 15 at Davis and Fairfax, Calif.; 

 Oct. 16 at Carmel and Ventura, Calif.; and Oct. 27 at Antioch, Calif. 

 Biological data associated with these specimens are: 9 with prey 

 (a salticid cT), Lafayette, Contra Costa County, Calif., Sept. 9, 1948, 

 E. G. Linsley; and 9, bred from Pseudotsuga taxifolia, Pialschie, 

 Wash., H. E. Burke. 



This subspecies occurs west of the Rocky Mountains, intergrading 

 with the subspecies archiiectus in Colorado, Arizona, New Mexico, 

 and northern Mexico. 



9b. Aiiplopus architectus architectus (Say) 



Plate 2, figure 30 



Pompilus architectus Say, 1836, Boston Journ. Nat. Hist., vol. 1, p. 302 (Leconte 

 edition, vol. 2, p. 744), 9 . Type: ? , Ohio (destroyed). 



Biology: Walsh and Riley, 1869, Amer. Ent., vol. 1, pp. 132, 163.— Wickham, 

 1898, Ent. News, vol. 9, p. 47. 



This subspecies differs in averaging a little larger, with paler iri- 

 descence, more long erect hairs, and the wings nearly hyaline. (See 

 the keys for a more exact comparison.) 



Say's description of architectus includes a description of the nests 

 and the places these are found. These biological notes fit the present 

 species very closely and show that the name^should be applied here 

 rather than to nigrellus or caendescens.
