wu Aconfiderable opening, or perforation under 
the penis, and at the bottom of, and be- 
tween the divifions of, the little horny bone. 
already fo often taken notice of. The Bee’s 
feed iffues copioufly at this opening. 
i IsGe lV. 
x The head of the peniform particle, which, 
however, has no opening, and affords no 
paflage to the feed.

The genital parts of the greater Hydrocantharus, 
or Water Beetle. 
a ‘The penis. 
&b The horny part of the penis, ferving to 
faften it on each fide. 
ce The root of the penis, | 
d The other tefticle in its natural fituation. 
e The tefticle {tripped of its air tubes, fo as to 
exhibit its internal ftructure.

gg The thickeft part of the faid veffes. 
bbhbbhbs Seven blind vefiels rooted in the pe- 
nis, and anfwering perhaps the purpofe of

The fpinal marrow of a male Bee, feen through 
the microfcope.

bb 1234567 Sevennodules, formed by the 
faid organ in its progrefs, and the nerves 
iffuing from the faid nodules. 
ecce Some nerves which {pring not from the 
nodules, but from the branches themfelves 
of the fpinal marrow. 
dadd, &c. Clefts, or longitudinal perforations 
in the fpinal marrow. 
e That part of the fpinal marrow, which lies 
in the head and neck. 
J That part which lies in the thorax. 
& That part which lies in the particle joining 
the thorax and abdomen. 
6 The abdominal part of the marrow. 
71 ‘Two confiderable nerves diftrubuted to the 
jaw bones, and other parts. 
&k ‘Two nerves running to the probofcis. Thefe 
are perhaps the infect’s guftalory nerves. 
ZI! Two other nerves, adminiftering to the 
guftatory nerves of the probofcis. 
mm “Iwo nerves, perhaps the optic ones; but 
I advance this with diffidence.

nital parts.

working Bees, as it appears, when infpected 
Jrom above, divided into tts regular hexagonal 
jections. This defeription could not be accu-

Some artificial lines.

Four cells of the working Bees, Separated from 
the other cells. 
a Three cells joined fide by fide to each other, 
and forming by the union, or meeting of 
their bafes, a cavity exadtly fitted to re-

6 The bottom of a fourth cell, in cafe the Bees 
fhould build one. Thus it may be feen, in 
what manner three cells, built one clofe to 
another, form by the fides of their bottoms 
a foundation for fupporting the bottom of 
another cell, to be built a contrary way. 
c¢ Part of a triangular foundation floping down- 
wards, and of the cell built upon the faid 
foundation. This is formed by the meeting 
of the fides of two cells. 
dd Two pretty long, or longer and unequal 
angles, or corners, formed by the hexagonal 
fides of the fame cell, and uniting with the 
former part c, fo as to form the foundation 
of another cell.

foundation is cut away. One fegment of 
this foundation remains united at one fide
