 Alberta and northern British Columbia south to Colorado, Utah and 

 central California. 



Host: Zelleria haimbachi Busck. 



IV. ATROCOXALIS GROUP 



A separate group is established for atrocoxalis because of the 

 unique ovipositor structure as described in the key. Apart from this 

 character the species might be included in the hispae group.

Female: Front wing about 4.3 mm. long; antenna with 21 segments; 

 ocelli rather small, lateral ocellus with diameter 0.63 times distance 

 from ocellus to eye; cheek about 0.27 breadth of mandible at base; 

 temple, as seen from above, strongly rounded and about 0.7 times as 

 long as eye; thorax and propodeum moderately stout; propodeum 

 rather evenly convex, with dorsomedial carina distinct on basal 

 0.66; sides of propodeum and region between and on either side of 

 carinae more or less finely rugulose; hind femur 4.4 times as long as
