or in the fields, in which they place this paste along with an egg; they 
then close the aperture with earth. 
In some the middle division of the ligula is enlarged at its extre- 
mity, almost cordiform, and folded when at rest.

Sometimes the body is glabrous, and the second and third joints of 
the antennze are almust of the same length. The superior wings pre- 
sent but two complete cubital cells. These Insects, being destitute of 
hairs, collect no pollen, and appear to deposit their ova in the nests of 
other Hymenoptera of this family. They are the HyLaus proper of 
Latreille and Fabricius * 
The others have a hairy body, and the third joint of the antennz 
longer than the second. ‘The superior wings have three complete cu- 
bital cells. The females collect their stores from flowers. I distinguish 
them by the generic name of 
Couueres, Lat. 
Such, for instance, is the 
C. qlutineug ; Apis succincta, Li; or the Abeille dont le nid est 
fait d’espéeces de membranes soyeuses of Reaumur, Insect., VI, xii. 
Small; black, with whitish hairs; those on the thorax, russet ; 
abdomen ovoid, and the posterior margin of its annuli covered 
with a white down, forming bands. The male—Evodia calen- 
daruwm, Panz.—has longer antenne. ‘The female makes a cy- 
lindrical hole in the ground, and smears its parietes with a 
gummy fluid, which may be compared to the viscid and glossy 
slime of a Snail. In this she piles a series of cells composed of 
the same material, resembling a thimble in shape, each containing 
an egg and some of the paste before mentioned fF. 
The other Andrenetze are distinguished from the preceding ones 
by the lanceolate figure of the lhgula. 
In some this ligula is folded against the superior side of its sheath, 
as in ANDRENA f, “and Dasy popa, Lat.§. The first joint of the pos- 
terior tarsi of the females of the latter subgenus is very long, and co- 
vered with long hairs in the manner of a little feather. The superior 
wings in these two subgenera have but two cubital cells.
