have, and transfer all references of Apis Virginica^ previous to that of 
Olivier, to Xylocopa^ and place the discovery of Bomhus Virginicus to 
the credit of Olivier, who gave the first indication with which we are 
able to separate it from the Apis Virginir.a of Drury, Linnaeus and 
Fabricius. Therefore, I offer the following as, probably, a more correct 
view of the synonymy of the latter species. 
Xylocopa Virginica. 
Apis Virginica. Dvmyj , Illust. Exot. Ins. i, p. 96, pi. 43, f. 1 (1770): Linn. Mant. 
Plant, p. 540. (1771); G-melin, ed. Linn. Syst. Xat. p,'2784 : Fabr. Syst. 
Ent. p. 380. (1775); Ent. Syst. ii, p. 318. (1793). 
Centris Carolina Fabr., Syst. Piez. p. 357. (1804). 
Xylocopa Carolina Say, Post. Jour, i, p. 412. (1837); St. Farg., Hym. ii, p. 
207. (1841); Smith, Brit. Mus. Cat., Hym. ii, p. 363. (1854). 
Xylocopa Virginica Westw., edit. Drury, Illust. Exot. Ins. i, pi. 43. fig. 1. 
(1837); Smith, Brit. Mus. Cat., Hym. ii, p. 362. (1854). 
2. B. impatiens. 
Bomhus impatiens Harris, Cat. Ins. Mass. 2d edit. 
Male. Head black, with a mixture of yellowish hairs below the 
antennae and on the cheeks and vertex. Thorax pale yellowish. Wings 
hyaline. Legs black, with pale hairs at base of the femora beneath. 
Abdomen with the first segment above pale yellow) remaining segments 
black. Beneath sparsely clothed with yellowish hairs. Length 7 lines. 
Female and teorher not seen. 
Seven specimens. Can., Conn., Pa., Ill., Mo. (Coll. Ent. Soc. Phil., 
and E. Norton.) 
The coloration of this species is so much like that of B. Virginicus., 
that, at first, I supposed it to belong to that species, but the males above 
described are so different from what I have taken for the males of 
B. Virginicus that they can scarcely be of the same species. A speci¬ 
men in the collection of Mr. Norton, labelled B. impatiens^ was com¬ 
pared with specimens so named in the Harris collection, and the above 
description made from it. It may be that this species and the males 
of B. Virginicus are mixed up, but until we have more conclusive evi¬ 
dence of their identity, it is probably best to keep them separated. 
3. B. Marylandicus. 
Apis Marylandica Fabr. Ent. Syst. Suppl. p. 273.
