squama elongate lanceolate, with a dense fringe of long oblique 

 bristles on both margins. 



Black. Labrum and mandible except basally reddish brown; 

 under edge of scape, palpi and front tibia brown; tibial spurs pale 

 brown; front tarsus brown; wings faintly tinged with brown; abdom- 

 inal segments 1 and 2 and sometimes the basal part of 3 rufous, the 

 other tergites and sternites often margined with a rufous tinge. 



Female: Forewing 7.0 to 7.7 mm. long; sensillae beginning at basal

longitudinal band of suberect stout hairs of rather uniform length 

 and about 0.5 as long as and much stouter than some scattered long 

 hairs. 



Black. Labrum and apical part of mandible reddish brown; 

 palpi, front tibia, and tibial spurs brown; front tarsus dark brown; 

 wings tinged with brown; abdomen rufous, blackish at the base of 

 the first segment. 



The type of michiganensis agrees externally with congrua as de- 

 cribed here but the squama is less elongate and attenuate apically, 

 and the subgenital plate broader. It may be an aberrant specimen 

 of the present species, but any decision as to its disposition is tentative 

 until better series are available for study.
