INSECTA. 
the two first are arcuated, and finally in the piece carrée which 
has neither palette nor silken brush. Their sexual organs re- 
semble two horns, partly of a reddish yellow, accompanied by 
a penis terminated en palette, and some other parts. If these 
organs be forcibly protruded the Insect dies instantly. 
The interior of the abdominal cavity of the females and la- 
bourers presents two stomachs, the intestines, and poison sac. 
A tolerably large aperture situated at the superior base of the 
proboscis, under the labrum, and closed by a little triangular 
piece called /angue by Reaumur, the epipharynx of Savigny, 
transmits the aliment and leads to a slender esophagus that tra- 
verses the interior of the thorax, and thence passes to the an- 
terior stomach, or rather crop, which contains the honey. The 
following stomach, according to Reaumur, contains the pollen 
or wax-like matter, and has its surface marked by annular and 
transverse ruge, in the manner of hoops. This abdominal ca- 
vity in the females contains two large ovaries composed of nu- 
merous sacculi, each of which encloses from sixteen to seventeen 
eggs. Each ovary terminates at the anus, near which it dilates 
into a pouch, where the egg is arrested, and receives a viscid 
humour furnished by a neighbouring gland. According to the 
observations of Huber, Jun., the inferior semi-annuli of the abdo- 
men of the labourers, the first and last excepted, have each, on 
their internal surface, two pouches in which the wax is secreted 
and moulded into laminz, that afterwards ooze out through 
the intervals between the rings. Under these pouches is a par- 
ticular membrane formed of a very small network, with hexa- 
gonal meshes, that unites to the lining membrane of the abdo- 
minal cavity. 
These observations on the internal anatomy of the Bee, with 
the exception of some few modifications, will apply to the Bom- 
bi properly so called(1). Wax, according to the experiments 
of the same naturalist, is nothing more than elaborated honey, 
and the pollen mixed with a little of that substance only serves 
as food for these Insects and their larve. 
M. Huber distinguishes two kinds of labourers or working 
Bees. The first, which he calls ciriéres, collect provisions and 
all the materials requisite for building, and employ the same. 
The second, or the nouwrrices (nurses), smaller and weaker, are 
formed for retirement, and their functions are almost re-
