COLEOPTERA. 377 



bristled, at least in several species, with pointed setae variously di- 

 rected,but arranged in eight longitudinal bands separated by smooth 

 intervals. The intestinal canal is very long, particularly in the Ne- 

 crophori and Necrodes. Its surface, in the latter, as well as in the 

 Silphae, is thickly studded with salient and granular points. It opens, 

 either laterally or directly, into a smooth enlargement, which, ac- 

 cording to Dufour Ann. des Sc Nat., Octob. 1824 may be com- 

 pared to a caecum. To the side is appended, a pediculated oval or 

 oblong bursa which constitutes a part of the excrementitious appa- 

 ratus. There are four biliary vessels, slender, extremely long and 

 very flexuous, each of which is separately inserted round the extre- 

 mity of the chylific ventricle. Dufour, lb., July 1825. From the 

 figure of the alimentary canal of the Necrophorus vespillo, given by 

 Randohr, it appears that the great intestine, instead of being covered 

 with granular papillae, is furnished with transverse muscular fillets, 

 forming annular plicae. 



N. vespillo; Silpha vespillo, L. ; Oliv., Col. II, 10, i, 1. From 

 seven to eight lines in length; black; three last joints of the 

 antennae red; elytra with two orange, transverse and indented 

 bands; coxae of the two posterior legs armed with a strong 

 tooth; the tibiae are curved. 



N. mortuorum, Fab.; Panz., Faun. Insect. Germ., XLI, 3. 

 Smaller; antennae entirely black; the second transverse orange 

 band of the elytra observed on the vespillo, usually forming a 

 large lunated spot. Found in woods, and frequently in mush- 

 rooms. 



N. germanicus, Fab.; Oliv., lb., 1, 2, a, b. More than an inch 

 long; all black; external margin of the elytra fulvous; aferrugi- 

 neous yellow spot on the front. 



N. humalor, Fab.; Oliv., lb. i, 2, c. Always smaller than the 

 germanicus, and differing from it in the orange hue of the an- 

 tennal club. 



North America produces several species, one particularly 

 N. grandis, Fab. that surpasses all others in size(l). 

 This genus seems to be confined to the northern districts of 

 Europe and America. 



Necrodes, Wilk. Silpha, Lin. Fab. 



The antennae manifestly longer than the head, and terminated by 

 an elongated club of five joints, the second of which is larger than 

 the third. The body is an oblong oval, with an almost orbicular
