8a. Dolichomitus messor sparsus, new subspecies 



Male: Differs structurally from the male of D. messor perlongus 

 as described in the key. 



Colored like the male of D. messor perlongus except that the scape 

 often lacks the pale spot in front, labial palpus usually has the first 

 two segments brown rather than only the first segment, the fulvous 

 markings are a little more reddish, and the fuscous markings on 

 the hind leg average a little paler. 



Female: Differs structurally from the female of D. messor perlongus 

 as described in the key. In color it differs in having the fulvous 

 coloration a little darker and the fuscous on the hind leg averaging a 

 little less distinct. The wings average a little darker than in the 

 subspecies perlongus and in most specimens from tbe Great Basin 

 they are heavily infuscate.

Paratypes (24 d", 469): From Alberta (Beaverlodge) ; Arizona (near 

 Alpine, Bear Wallow on Mount Lemmon, and Parker Creek in the 

 Sierra Ancha) ; British Columbia (MacGillivray Creek Game Reserve 

 near Chilliwack, 100 Mile House, Robson, and Vancouver) ; California 

 (Antioch, Buck's Lake in Plumas Co., Clarksburg, Convict Lake, 

 Dardanelle, Fish Camp, Hope Valley in Alpine Co., Leevining, Mam- 

 moth, Meadow Valley, San Francisco, Saticoy, Truckee, Vade, and 

 Yosemite); Colorado (Cheyenne Canyon, Mount Harris, and North 

 Cheyenne Canyon) ; Idaho (Coeur d'Alene and Riggins) ; New Mexico 

 (Jemez Springs); Oregon (Alkali Lake, Hood River, Portland, and 

 Seaside) ; Utah (Logan, Provo, Stansbury Island in Tooele Co., and 

 Uinta Co.); Washington (Buckley, Easton, Ellensburg, Loon Lake, 

 Mount Rainier at 4,700 ft., and Puyallup); Wyoming (Yellowstone 

 National Park); and Yukon (Whitehorse). 



Collection dates are mostly in spring, early summer, and fall, with 

 a few records in late summer. The only records between July 19 and 

 September 11 are: August 10 at Seaside, Oreg.; August 11 at White- 

 horse, Yukon; and August 18 at Logan, Utah. Of the 24 males 20 were 

 taken on various dates between April 24 (at Ellensburg, Wash.) and 

 May 26 (at Vancouver, B. C). The other four were taken June 15 

 at Truckee, Calif.; July 3 at Dardanelle, Calif.; July 15 at Fish Camp, 

 Calif.; and July 19 at 4,700 ft. on Mount Rainier, Wash. It may be 

 that the early males represent a first generation and the later males a 

 second generation but the seasonal records for females are not con- 

 sistent with this possibility. Unusually early and late records for 

 females are: March 31 at Antioch, Calif.; May 13 at Bear Wallow, 

 Mount Lemmon, Ariz.; May 16 at Loon Lake, Wash.; May 24 near 

 Alpine, Ariz.; May 26 at Vancouver, B. C; October at Provo, Utah;
