Hah. Jalapa, Mexico. Mr. J. Akhurst. (Coll. E. Nortpn.) 
This is the handsomest species of Bomhus known to me, and were it 
not for the rufous color on the second and third segments of the abdo¬ 
men, which is very conspicuous, I should have considered it as the B. 
ephippiatus of Say, but he mentions no such color in his description.

Bomhus violaceus St. Farg. Hym. 1, p. 473. 
“ Black. Feet black; hairs of the under part of the tibiae and tarsi 
rufous. Wings fuscous, with a violet reflection. Female. Length 13 
lines. Worker.^ like the female. Length from 5 to 7 lines. North 
America.” 
I have not seen this species, and doubt very much that it occurs in 
North America. The British Museum have specimens of it from South 
America. 
In addition to the species above described, the following European 
species have been mentioned as found in North America:— 
B. hortorum Linn. Smith, Entom. Annual. 1857, p. 30. Lake Winnepeg. 
B. Derhamellus Kirhy, Faun. Bor.-Amer. 4, p. 273. Arctic America. 
B. hyperboreus Dahlh. Schiodte, in Etzel’s Gironland., p. 611. Greenland. 
B. balteatus -Z)a^^5. Schiodte, ^ 
In the collection of Mr. Norton, there is a single specimen, a worker, 
collected in New Jersey, by Mr. J. Akhurst, which answers so well to 
the description given by Mr. Smith of that sex of B. pratorum., a 
European species, that I do not feel justified in separating them.
