of Buprestide and Elateride. 
BUPRESTIDA. 
Six Malpighian vessels, of 
which the ends are fixed to the 
angle of the intestine. 
The folliculi testium very long, 
tubular, at the base elliptically 
dilated ; the ends of all the folli- 
culi in each testis twisted into a 
spiral ; each testis furnished with 
its own enclosing membrane. 
Two pairs of vesicule semi- 
nales,—one thick, pear-shaped ; 
the other long, tubiform, closely 
twisted. 
Spermatheca very simple, elon- 
gated, club-shaped, without ac- 
cessory gland *. 
The ventral cords of the ner- 
vous system separated in their 
entire length. 
The ganglia of the mesothorax 
and metathorax coalesced. 
Five abdominal ganglia ; only 
the last three in the abdominal 
cavity. The first abdominal gan- 
glion distinct from the metatho- 
racic ganglion.

ELATERIDA. 
Four Malpighian vessels, with 
free ends. 
The testes free; the folliculi 
short, more or less round, mutu- 
ally free. 
Three pairs of vesicule semi- 
nales, of which two pairs vary 
exceedingly in structure. 
Spermatheca of extremely vary- 
ing, often very complicated struc- 
ture, with large ramified acces- 
sory gland. 
The ventral cords of the ner- 
vous system separated only as far 
as the metathoracic ganglion. 
All thoracic ganglia sepa- 
rate. 
Eight abdominal ganglia; the 
last six situated in the abdominal 
cavity. The first abdominal gan- 
glion united with the metathora- 
cie ganglion.

The investigations of which we have given the results in the 
preceding pages prove that the mutual relation of these two 
families is very different from what was formerly supposed. 
With regard to development, structure, and habits of life, they 
appear as widely separated as two families can be, within the 
boundaries of the same principal division of animals. Amongst 
Serricornia, Buprestidze occupy, in all stages of life, the same 
place as Cerambycidze and, more particularly, Lamini (Lamia, 
Saperda, &c.) amongst the phytophagous or cryptopentamerous 
Coleoptera. Hlateridze, on the contrary, ave carnivorous as larve, 
and in that stage of their life very like the larve of Carabide, 
from which it follows (on account of the influence of the genera- 
tive life on the structure) that also in their perfect state Elateridz 
* In the paper above quoted on the anatomy of Buprestidae, the bursa 
copulatrix is erroneously represented as spermatheca, and the true sperma- 
theca as accessory gland—an error which was easily rectified by the use of 
a better microscope.
