 on a short collecting trip in Japan. 



Key to the Nearctic species of Laufeia 



1. Propodeum with distinct median longitudinal carinae; first tergite with median 

 longitudinal carinae distinct on the basal 0.7 ± ; hind tibia with broad apical 



and subbasal fuscous bands (fig. 332,1) 1. slossonae (Davis) 



Propodeum without median longitudinal carinae; first tergite with median 

 longitudinal carinae distinct on the basal 0.3 ±; hind tibia with indistinct 

 apical and subbasal infuscation (fig. 323, a) .... 2. navajo, new species

 Type: ? , Mount Washington, N. H. (Philadelphia). 



Front wing of male 2.9 to 5.8 mm. long, of female 3.2 to 5.8 mm. 

 long; body and legs moderately robust; lateral longitudinal carina of 

 propodeum distinct except basally; median longitudinal carinae of 

 propodeum distinct on basal 0.7 of propodeum; petiolar area of pro- 

 podeum more or less distinct; propodeum with short transverse rugulae 

 between its lateral and pleural carinae and long transverse rugulae 

 near base of its petiolar area; first tergite about 1.87 as long as wide in 

 male, about 1.65 as long as wide in female, its median longitudinal 

 carina distinct on its basal 0.7 ±. 



Black or blackish brown. Face of male except narrow lateral and 

 ventral margins, spot of variable size on face of female below each 

 antennal socket (the spots sometimes united to make a large whitish 

 blotch in upper part of face), sometimes part or all of clypeus of male, 

 palpi, scape and pedicel except above, more or less of lower part of 

 propleurum and lower corner of pronotum, tegula, hind corner of 

 pronotum, and ground color of legs, ivory, the femora of female usually 

 pale fulvous; flagellum dark brown, paler below, stramineous basally 

 below; mesosternum, lower 0.6 to all of mesopleurum, often the meta- 

 pleurum, and often more or less of mesoscutum fulvous; scutella ivory 

 to fulvous; very narrow apex of front femur and moderately narrow 

 apex of middle femur infuscate; front tibia with weakly infuscate 

 subbasal and apical bands; front tarsus with a faint apical infuscation 

 on each segment; middle tibia and tarsus with infuscate markings as 

 on the front tibia and tarsus but a little darker; hind femur infuscate 

 basally and apically and usually with a weak longitudinal infuscate 

 stripe on its front side connecting the basal and apical bands; hind 

 tibia with broad apical and subbasal fuscous bands ; apex of first four 

 segments of hind tarsus fuscous; fifth segment of hind tarsus fuscous, 

 its base pale.
