450 CLASS INSECTA. 



sents no peculiar prominence, and the crooks of the tarsi are 

 always simple. The anterior tarsi are often wanting in many, 

 either from their birth or through decay. 



The alimentary tube is always very long, and this length 

 is even sometimes {Copris lunaris), ten or twelve times more 

 considerable than that of the body. The chylific ventricle, 

 occupying the major part, is bristling with conoid papillae, or 

 in the form of nails, very much folded upon itself, and sus- 

 tained in this state of agglomeration by numerous trachean 

 bridles. The intestine is filiform, and terminated by an in- 

 flation. The testicles of the coprophagi, dissected by M. 

 Dufour, appeared to hira to be composed of six spermatic 

 capsules, orbicular, a little depressed, usually united by some 

 tracheae into a packet, each carried on a tubular pedicle, tole- 

 rably long, and which leads to a deferential canal of no great 

 length. There is but one pair of vesiculae seminales ; they 

 are filiform, very long, and very much folded. 



This first section corresponds to the third division of the 

 genus Scarabaeus of Olivier, or to that of Bousier {Copris), 

 but adding some Scarabaei {Aphodus) of this naturalist. 



Some have the two intermediate feet much more separated 

 at their origin than the others. The labial palpi are very 

 hairy, with the last articulation much smaller than the others, 

 or even very indistinct. There is either no scutellum, or a 

 very small one, and the anus is uncovered. 



Some Coprophagi of this division, proper to the ancient 

 continent, with rounded body, usually depressed above, or 

 but little gibbous, similar, or but little different, and without 

 horns in the two sexes ; in which the antennae with nine ar- 

 ticulations are terminated in a foliated knob, without scu- 

 tellum, or any sutural hiatus indicating its place ; in which 

 the four posterior limbs, usually furnished, as well as the 

 tarsi, with fringes of hairs, or lashes, are slender, elongated, 

 little or not at all dilated at their extremity, truncated
