1. Carria dreisbachi, new species 



Figures 174,b; 182,i 



Front wing 3.5 to 5.0 mm. long; combined face and clypeus 1.4 to 

 1.7 as wide as high, with coarse subadjacent punctures and centrally 

 with a tendency to transverse wrinkling between the punctures; 

 outer face of mandible weakly convex, its upper and lower edges not 

 margined, about 2.55 as long as wide; thorax about 2.0 as long as 

 high; third lateral area of propodeum sub vertical ; opening of propodeal 

 spiracle approximately circular; median dorsal carinae of first tergite 

 ending at about 0.4 to 0.65 its length; abdomen depressed basally, 

 apically subcylindric in male, somewhat compressed in female; 

 second abdominal tergite 0.90 to 1.25 as long as wide. 



Black. Apical half of mandible more or less ferruginous; palpi pale 

 fulvous; tegula yellowish to fulvous; legs light ferruginous, their 

 coxae partly blackish and the femora and tibiae sometimes more or 

 less infuscate. 



There are three subspecies, as keyed and described below: 



1. Hind femur ferruginous with a weak infuscation to strongly infuscate, uncom- 



monly clear ferruginous; hind coxa entirely black or with the apex ferrugi- 

 nous, uncommonly with as much as the apicoventral third ferruginous; 

 range: Mountains of Colorado, Arizona, and New Mexico. 



lb. dreisbachi montana, new subspecies 

 Hind femur clear ferruginous; hind coxa almost entirely black to mostly fer- 

 ruginous 2 



2. Second abdominal tergite about 0.90 as long as wide; range: Alleghenian and 



Carolinian faunas la. dreisbachi dreisbachi, new subspecies 



Second abdominal tergite about 1.1 as long as wide in male, about 1.2 as long 

 as wide in female; range: Sierra Nevada of California. 



lc. dreisbachi californica, new subspecies 



la. Carria dreisbachi dreisbachi, new subspecies 



Second abdominal tergite about 0.90 as long as wide; outer face of 

 mandible with moderately coarse punctures. 



Legs light ferruginous. Middle coxa sometimes more or less blackish 

 basally and above, but always ferruginous beneath; hind coxa varying 

 between having the basal hind part infuscate and all but the ventro- 

 apical third infuscate.
