 eriogoni (Rohwer). Alta., Colo., N. Mex., Ariz.; Mexico (Chihuahua, Coahuila, Zacatecas, 



Durango, Mexico). Ecology: Nests in softer spots of rocky root-shrouded stream banks; 

 apparently nests in pre-existing burrows of other insects and makes a sometimes 

 branched burrow 8-16 cm long; makes up to 3 cells per nest in a small cluster at end of 

 burrow and stores 18-22 prey per cell. Prey: Pipunculidae, Chloropidae, Tephritidae, 

 Empididae, Chamaemyiidae.

 lentus (Fox). Que. west to B. C, Yukon Terr., N. W. T., Alaska south to Fla. and N. Mex., 



apparently not occurring west of Rocky Mts. in U. S. Ecology: Nests in vertical banks 

 of sand and in stony, root-shrouded banks of firm clayey sand; pre-existing burrows are 

 used and new side branches are constructed with clusters of cells located around, off to 

 the side, or at the end of the main burrow; burrows are 7.0-10.5 cm long, linear or 

 branched; up to 12 cells per nest with 5-30 prey per cell, newly captured prey stored at 

 end of burrow, not in cell. Prey: Simuliidae, Chloropidae, Empididae, Ceratopogonidae, 

 Chironomidae, Agromyzidae.

 maculiclypeus (Fox). Newfoundland west to B. C, Yukon Terr., N. W. T., Alaska, south to Pa. 

 and Kans. in the east, and to N. Mex. and Calif, in the west. Ecology: Nests in sparsely 

 vegetated sand, burrows 4.0-11.5 cm long, extremely variable in shape, but main burrow 

 usually enters at acute angle to surface; entrances usually concealed under small sand 

 ledges or leaves, at bases of plants, or in depressions; cells arranged in clusters at the 

 end of or off to the side of the main burrow with up to 9 cells per nest, each cell with 

 5-20 prey; pre-existing burrows are often used but new burrows are begun in small 

 crevices or depressions in sand; newly captured prey sometimes stored in open cell at 

 end of burrow, sometimes at end of burrow in a section only slightly or not at all 

 widened. Prey: Helobia sp., Molophilus sp.; Palpomyia sp.; Cricotopus sp., Hydrobaenus 

 sp., Chironomidae sp.; Bradysia sp.; Drapetis sp., Hilara femorata Lw., Platypalpus
