114 INTERNAL ANATOMY OF INSECTS. 
pkord). In the only two that appear to have been ex- 
amined, Rhynchites Bcluleti and Cryptorhynchus Lapullti, 
that canal is moderately long, the stomach partially 
shaggy, and the small intestine inversely claviform ; but 
in other respects they differ materially a . In the former 
there is no crop or gizzard, the stomach is fringed on 
each side, except at its upper extremity, with a series of 
small civca or shags, and there are three pairs of bile- 
vessels b ; while in the latter the gullet is dilated into a 
crop which includes a gizzard in which the skill of a 
Divine artist is singularly conspicuous: — though so 
minute as scarcely to exceed a large pin's head in size, 
it is stated to be armed internally with more than 400 
pairs of teeth, moved by an infinitely greater number of 
muscles c . A transverse section of this gizzard represents 
two concentric stars, with nine rays each d : the object of 
this structure is, the comminution of the timber which 
this beetle has to perforate and probably devour °. The 
stomach is very slender, but dilates in the middle into a 
spherical vesicle f , and there are only two pairs of bile- 
vessels g . In the Capricorn beetles, the part we are con- 
sidering varies much : in general we may observe that it 
is more than double the length of the body, that the sto- 
mach is long and slender, and usually naked, that the 
gullet terminates in a crop without a distinct gizzard, 
and that there are three pairs of bile-vessels h . In the 
Herbivorous beetles {Chrysomela, Cassida, &c.) the canal

the size of the insect, it appears that the gizzard could scarcely have 
been of greater diameter. d lbid.f. 2.
