ICHNEUMON-FLIES — GELINAE : MESOSTENINI 191 



white and that base of tegiila of male is white, at least in the specimens 

 at hand. Sometimes the femora are red (these specimens resembling 

 T. r. relativus) and sometimes black (resembling T. r. nitschei). 

 There seems to be a tendency for red-femured specimens to occur 

 in the northern part of the range (as in T. r. relativus) and for black- 

 femured specimens to occur in the southern part (as in T. r. nitschei). 

 Judging largely from the distributional data published by Pratt, 

 however, the ranges of both red-femured and black-femured specimens 

 overlap or intermingle to such an extent that it seems inadvisable to 

 keep the two forms as subspecies. 



The type of Cryptus rugulosus is an abnormal, brachytic specimen, 

 with the temple strongly convex and the hind femur only 3.8 as long 

 as deep. On the basis of other characters, however, it belongs here. 



Specimens (17 cT', 209): From Alaska (Eagle); Alberta (Banff); 

 Arizona (Bright Angel Trail in Grand Canyon and Oak Creek Canyon) ; 

 British Columbia (Fort Nelson, Glenora, Hope Mt. at 6,000 ft., 

 Lillooet, Nicola, Pavilion Lake, and Vernon); Colorado (Boulder, 

 Fort Collins, Gothic at 9,500 ft., Longs Peak Inn at 9,000 ft., and 

 Los Pinos); Idaho (Twin Falls and Wendell); New Mexico (Cedro 

 Canon in Bernalillo Co., Farmington at 5,250 ft., Jemez Springs at 

 6,400 ft., and Santa Fe); Oregon (Corvallis and Grant Co.); Utah 

 (Beaver Creek Hills in Beaver Co., Fort Duchesne, Logan, and 

 Zion Park); and Washington (Mill Creek near Walla Walla and 

 Pullman). 



Most collection dates are from May 22 to August 3. Those 

 outside of this range are: May 10 at Zion Park, Utah; May 13 in 

 Oak Creek Canyon, Ariz.; May 19 in Cedro Canon, Bernalillo Co., 

 N. Mex.; August 4 on Bright Angel Trail, Grand Canyon, Ariz.; 

 and October 6 at Farmington, N. Mex. 



This subspecies occurs in the Rocky Mountain and Great Basin 

 areas.
