INTERNAL ANATOMY OF INSECTS, 107 
least the Staphylinide and Silphida, there is little or no 
crop —the gizzard is hidden: in the former, the whole 
length of the intestinal canal is not twice, while in the 
latter it is more than four times that of the body*. In 
these also the intermediate portion of the large intestine 
is singularly annulated>. In the Lamellicorns the sto- 
mach is usually longer than all the rest of the intestines 
together, and often convoluted: in the cockchafer the 
whole intestinal canal is nearly jive times the length of the 
body, four parts of which is occupied by the stomach‘. 
In the grub the canal scarcely exceeds the length of the 
animal’. In Lampyris the stomach exhibits a remark- 
able appearance, having on each side a series of spheri- 
cal folds or vesicles®. Have these any thing to do with 
the secretion of its phosphoric matter? Tenebrio has a 
gizzard armed internally with calluses, and a shaggy sto- 
mach, and Blaps does not differ materially; their entire 
canal is more than twice the length of the body’. In the 
vesicatory beetles (Cantharis, Meloe, &c.) there is no giz- 
zard, and the canal is less than twice the length of the 
body &. Little is known with regard tothe alimentary canal 
of the beetles distinguished by a rostrum (Curculio L.). 
In the only two that appear to have been examined, Afte- 
labus Betuleti and Cryptorhynchus Lapathi, that canal is 
moderately long, the stomach partially shaggy, and the 
small intestine inversely claviform ; but in other respects 
they differ materially», 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 ca@ca or 
shags, and there are ¢hree pairs of bile-vessels'; while
