which are hyaline, faintly stained with fuscous. The second segment of the ab¬ 
domen above has some short yellowish or yellowish-brown hairs in the middle of 
the anterior margin, and the hairs on the middle of the first segment are some¬ 
times shaded with brown. In 110 specimens before me of B. Virginicus 9 > 9 
and , there is not the least change in the color of the hairs on the first seg¬ 
ment of the abdomen which are always yellowish-white, and there is no mix¬ 
ture of yellowish hairs on the second segment. The description of this species 
(ibid. p. 87) should be altered to read as follows :— 
“ Bombus Virginicus, Oliv. 
‘‘Female. Head black, clothed more or less with yellowish hairs above the 
antennae. Thorax above and on the sides yellowish-white, somewhat mixed 
with black between the wings. Legs blac^c, except the base of the femora be¬ 
neath, which is sometimes slightly clothed with yellowish hairs; tarsi brown, 
basal joint rufous on the inner side. Abdomen with the first segment above 
yellowish-white, the hairs less dense in the middle of the segment; remaining 
segments black. Beneath black. Length 9—12 lines. 
<< Worke7\ Differs from the female only in size. Length 5—7 lines. 
“ Male. Colored like the female and worker, except that the face below the 
antennae, the cheeks, vertex, femora and abdomen beneath more or less clothed 
with yellowish hairs, those on the face below the antennae entirely yellowish. 
Length 4 :-}—7 lines. 
‘‘To the list of synonyms of this species (ibid. p. 87), add Bombus impatiens 
Harris, Cat. Ins. Mass. 2d edit. Cresson, Proe. Ent. Soc. Phil, ii, p. 90^^. 
“Since writing my remarks on the Apis griseocollis DeGeer, (ibid. p. 88), I 
am rather inclined to think that the males and workers described by him, be¬ 
long, not only to two different species, but to different genera. His description 
of the worker is probably that of Bombus Virginicus Oliv., but his description 
of the male, seems to refer to the male of Xylocopa Virginica, — the ‘large’ 
size, ‘with large eyes which cover almost the whole of the head,’ the ‘yellow 
upper lip,’ and the ‘blue shade of the abdomen and legs,’ are conspicuous cha¬ 
racters in the male of the latter species, but not in B. Virginicus, or any other 
species of Bombus known to me. It is probable that M. Acrelius may have 
captured males of X. Virginica in the vicinity of the nest where he found the 
worker of his griseocollis, and from the similarity of the coloration, he, as well 
as DeGeer, may have thought that they belonged to the same species.’’
