in a mutilated condition, and I had the misfortune to injure my 

 own, I am therefore compelled to adopt the course I have done,

21. Halictus subfasciatus, 



H. ater, griseo-subpubescens, abdomine mtidissimo, segmentis

 Halictus subfasciatus, Nyland. Ap. Boreal, p. 200. 



Female. Length 3 lines. Black, the apical portion of the 

 flagellum fulvo-piceous beneath ; the disk of the thorax finely 

 and closely punctured, subopake ; the metathorax truncate, at 

 the base an enclosed portion which has on each side a slight 

 ridge, and terminates posteriorly at the verge of the trun-

Male. Length 3 lines. Black, the flagellum beneath pale ful-

 the species is found in Sweden, Finland, and Lapland. 



22. Halictus fulvicornis. 



H. niger ; antennis thorace longioribus, subtus fulvescentibus, 

 supra subfuscis ; abdomine nitido, segmentis intermediis basi
