B. variegatum Say.— Trans. Am. Phil. Soc. 1823, II, p. 89. 
A very variable species. As defined by me, it includes patruele 
Dej. and conspersum Chaud., there being apparently no constant char¬ 
acters for their separation. 
Habitat: The greater part of the United States and Canada from 
the Atlantic to the Pacific. 
B. nigripes Kirby— Faun. Bor. Am. 1837, IV, p. 57 ( Notaphus ). 
Capable of but feeble distinction from the preceding. The legs are 
dark piceous or black, and the form is rather less elongate, while the 
size averages somewhat smaller. 
Habitat: Anticosti and the Gulf of the St. Lawrence, the Lake 
Superior region, Manitoba, Alberta, the Rocky Mountains, Oregon, 
Washington, British Columbia and Vancouver Island. 
B. intermedium Kirby. — Faun. Bor. Am. 1837, IV, p. 58 
{Notapkus). 
Habitat: Illinois, Manitoba, Montana, Nebraska, Kansas, In¬ 
dian Territory, Mississippi, Texas, Colorado, New Mexico, Arizona 
and southern California. 
B. timidum Lee .—Ann. Lyc. 1848, IV, p. 460 ( Ochthedromus). 
Habitat: Lake Superior region, Manitoba, Colorado, Utah, 
Nevada and along the Pacific Coast from California to British Columbia. 
B. versicolor Lee.— Ann Lyc. 1848, IV, p. 460 {Ochthedromus). 
Habitat: The greater part of the United States and Canada. 
B. constrictum Lee.— Ann. Lyc. 1848, IV, p. 462 ( Ochthe¬ 
dromus r). 
Habitat : The Atlantic Coast, extending westward to the Rocky 
Mountains and Texas. 
B. contractum Say. —Trans. Am. Phil. Soc. 1823, II, p. 85. 
Closely allied to the preceding, but differs, in addition to the char¬ 
acters above given, by its more slender and elongate form. 
Habitat : The Atlantic States from Massachusetts to Florida and 
westward to Ohio and Tennessee. 
B. morulum Lee. —New Species Coleopt. 1863, pt. i, p. 19. 
Habitat: Hudson Bay Territory. 
B. mutatum G. & H. —Cat. 1868, I, p. 416. 
Habitat: Hudson Bay Territory, Mt. Washington, N. H., Lake 
Superior region and high altitudes in the Rocky mountains.
