2. Subinterrupta (partly interrupted). Builds underground. 
General colour black; the front of the thorax and belt (sometimes 
broken or interrupted) on the front of the abdomen yellow; the 
extremity pale red. This and the first described species builds under¬ 
ground, may be observed, at the commencement of spring, frequenting 
the flowers of the Crocus, and afterwards those of the Gooseberry. 
3. Hortorum (garden humble bee). General colour black; the 
front and back of the thorax and front of the abdomen bright yellow; 
the extremity white. There are two varieties of this species—one 
instead of yellow has hair of a dark buff colour, like faded yellow hair ; 
the other variety is smaller in size, and altogether darker in colour. 
This bee, as its name implies, is abundant in most gardens ; builds 
underground. 
4. Muscorum (Moss humble bee). The adult female has the 
thorax of a bright fulvous or yellowish red ; the hair of the abdomen, 
paler and rather thin, leaving each segment, and the dark colour of the 
body, distinctly visible. The young bees are paler in colour according 
to age ; this species is about the same size as that last described ; it 
forms its comb on the ground, and covers it with moss ; it makes its 
appearance in the spring, at the time that the Violet comes into blossom. 
5. Floralis (floral). This species differs from the preceding, chiefly 
in size, being a full third less; it also has the hair on the abdomen 
brighter, and the segments more clearly marked. There are one or two 
other species or varieties, which are with difficulty distinguished from 
the above ; they all form their comb on the ground, and cover it with 
Moss. 
6. Tunstallana (Tunstall’s bee). General colour black; the front 
and back of the thorax tawny, and the end of the body (except the 
extreme point), white. Some few specimens, instead of tawny, have 
yellow hair on the parts above mentioned; builds underground; this 
bee is attracted by the blossoms of early Beans. 
7- Sylvarum (the wood bee). The body and front of the head are 
covered with whitish hair, except the thorax between the wings, which 
is black, and the end of the abdomen, which is tinged with rusty red ; 
on the abdomen the hair is thin, leaving its segments distinctly visible ; 
builds underground. This bee is partial to the blossoms of the mallow 
tribe. 
8. Vestalis (the vestal bee). This is a fanciful name derived from 
the priestesses, who guarded the sacred fire of Vesta, amongst the 
ancient Romans. General colour black, with a broad band of tawny 
yellow on the front of the thorax ; the top of this, and two-thirds of 
the abdomen, are naked and shining ;—the other third is covered with 
white hairs, margined at the top by a narrow interrupted line of bright 
yellow; these white and yellow hairs have suggested, I suppose, the 
idea of fire and an altar. This is a rare bee, but may be seen occasion¬ 
ally on the flowers of the Hollyhock. 
9. Campestris (bee of the plains). General colour black. The 
front of the thorax is marked with a belt of tawny yellow, and its back 
with a patch a shade darker in colour ; the abdomen, towards its 
extremity, is ornamented on each side with a semi-circular tuft of pale
